The term "and/or" refers to and includes any and all possible combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present invention provides a vehicle-mounted KTV control method, including:
and S10, carrying out voice suppression processing on the initial audio signal to obtain a first audio signal. The voice suppression comprises voice elimination and voice weakening, and the initial audio signal is a vehicle-mounted multimedia audio signal.
Referring to fig. 2, the initial audio signal V10 is an unprocessed multimedia audio signal, in which the human voice ratio is greater than the accompaniment ratio. The first audio signal V11 is a multimedia sound signal of the original audio signal V10 subjected to a vocal suppression process, wherein the accompaniment ratio is greater than the vocal ratio, and is suitable for being used as the audio signal of the K song.
The voice suppression process includes a voice elimination process and a voice weakening process. The voice eliminating process is to reduce the voice proportion of the initial audio signal to zero, and the voice weakening process is to reduce the voice proportion of the initial audio signal to be lower than the accompaniment proportion, so that the voice of the user is harmonious with the accompaniment in the K song.
In one embodiment, the initial audio signal V10 may be an audio file stored on the vehicle-mounted smart internet terminal or an audio file obtained in real time through wireless communication or the like. The first audio signal V11 can be stored temporarily or for a long time at the vehicle-mounted intelligent internet terminal, so as to provide accompaniment for the user to K songs.
In one embodiment, the vehicle-mounted intelligent networking terminal comprises a multimedia system, such as a multimedia player and a display, wherein the multimedia player is used for playing audio files, and the display is used for displaying multimedia files.
And S20, picking up the audio signals of the environment in the vehicle and carrying out echo cancellation and voice positioning processing to obtain at least one initial voice signal. Wherein the ambient audio signal comprises a first audio signal, a human voice signal and a noise signal.
The current K singing system needs a mobile terminal and an additional microphone system for supporting, a receiver of the mobile terminal is used for collecting voice, then the voice is sent to the microphone system through Bluetooth or NFC, then the voice and music of the mobile terminal are processed by the microphone system to generate a third audio signal, and the third audio signal is sent to a vehicle machine in an FM mode to realize the function of K singing. However, when FM channels conflict, the karaoke system cannot realize 2-or multi-person chorus. And this embodiment need not to adopt the FM mode to send to the car machine, does not have the condition of FM channel conflict, has realized the function of many people K singing simultaneously.
Specifically, when picking up sounds, in addition to the user's voice, the accompaniment and noise played in the car are also picked up. Therefore, by performing echo cancellation on the in-vehicle environment audio signal, noise and echo can be cancelled, and then by the human localization processing, for example, distinguishing whether the sound is emitted by the main driver, the sub-driver or the rear row, the sound source can be determined. Thus, a relatively pure initial human voice signal is obtained.
In a certain embodiment, the vehicle-mounted intelligent internet terminal further comprises a microphone, and when the vehicle enters a karaoke mode, the microphone starts to pick up an in-vehicle environment audio signal. Since the microphones in the car usually comprise multiple branches, the multiple microphones are operated simultaneously. Taking 2 to 4 branches as an example, one microphone is used as one input.
When multiple persons simultaneously sing K exist in the vehicle, the initial personal sound signals of all the members in the vehicle can be obtained by processing the environment audio signals in the vehicle. Referring to fig. 2, assuming that 4 members in the vehicle are in karaoke at the same time, step S20 may output 4 initial vocal signals, i.e., initial vocal signals V20, V21, V22, and V23, respectively.
Referring to fig. 3, in one embodiment, the step S20 includes the following sub-steps:
and S21, picking up the environment audio signal in the vehicle.
And S22, performing echo cancellation processing on the environment audio signal according to a preset echo cancellation algorithm. Among them, echo cancellation algorithms include an echo suppression (acoustic echo suppression) algorithm and an acoustic echo cancellation (acoustic echo cancellation) algorithm.
The echo suppression algorithm was an earlier echo control algorithm. Echo suppression is a non-linear echo cancellation that compares the level of sound intended to be played by a loudspeaker with the level of sound currently picked up by a microphone by a simple comparator, and if the former is above a certain threshold, then it is allowed to pass to the loudspeaker, and the microphone is turned off to prevent it from picking up the sound played by the loudspeaker and causing a far-end echo. If the sound level picked up by the microphone is above a certain threshold, the loudspeaker is disabled for echo cancellation purposes.
Acoustic echo cancellation Algorithms (AEC) are based on the correlation of the loudspeaker signal with the multipath echoes it generates, creating a speech model of the far-end signal (s (n)), using it to estimate the echo (e' (n)), and continuously modifying the coefficients of the filter so that the estimate more closely approximates the true echo (e (n)). Then, the echo estimation value is subtracted from the input signal of the microphone, so as to achieve the purpose of eliminating the echo.
And S23, carrying out voice positioning processing on the environmental audio signal after the echo cancellation according to a preset sound source positioning algorithm to obtain at least one initial voice signal. The sound source positioning algorithm includes a Time-Delay Estimation (TDE) algorithm and a generalized cross-correlation (GCC) Time-Delay Estimation algorithm.
Sound source localization is the spatial arrangement of microphones in a geometric array to receive sound field information of the noise of an object, and the azimuth information of the object is determined by detecting or calculating the time delay of the signal measured by each microphone. In this example, the positions of the multiple microphones may be determined.
The time delay estimation algorithm utilizes time delay estimation caused by different signal propagation distances among sensors or sensor arrays to finish combined direction finding and distance measuring of a target; if the time delay value existing between the arrival of the sound wave at each array element can be accurately estimated, and the parameter estimation quantity of the target position can be calculated according to the geometric relationship of the microphone array arrangement.
The GCC method is a conventional TDE method. Since there is a certain correlation between signals from the same sound source, the TDE value can be estimated by calculating the correlation function between signals received by different microphones. However, in practical environments, due to the influence of noise and reverberation, the maximum peak of the correlation function is weakened and sometimes multiple peaks occur, which make the actual peak detection difficult. The GCC method weights the signal in the power spectrum to emphasize the relevant signal portion and suppress the noise-disturbed portion, so as to make the peak value of the correlation function at the time delay more prominent.
And S30, carrying out sound modulation on the first audio signal and the initial human voice signal to obtain a target audio signal.
Mixing (Audio Mixing) is a step in music production, where sound from multiple sources is integrated into a Stereo (Stereo) or Mono (Mono) soundtrack. These original sound signals may come from different musical instruments, voices or orchestras, respectively, which are recorded in live performance (live) or recording rooms. In the process of sound mixing, the frequency, dynamics, tone quality, positioning, reverberation and sound field of each individual original signal are independently adjusted to optimize each sound track, and then the sound tracks are superposed on a final finished product. In this embodiment, the first audio signal and the initial human voice signal are subjected to sound modulation, so as to obtain a mixed target audio signal.
The Mixing device can be a synthesizer (Sound Module), an audio Processor (Signal Processor) and a Mixing Console (Mixing Console), or Mixing software, so as to complete complex Mixing operation. In this example, by processing with a preset mixing algorithm, when the first audio signal and the initial human voice signal are input to the mixing device or mixing software, mixing processing is automatically performed, and a mixed target audio signal is output. The mixing step includes, but is not limited to, rail aligning, modifying, noise reduction, excitation, tooth sound removal, equalization, and compression.
In one embodiment, the vehicle-mounted intelligent internet terminal further comprises a DSP audio processor, and the DSP audio processor is configured to perform sound modulation on the first audio signal and the initial human voice signal to obtain the target audio signal.
Referring to fig. 4, in one embodiment, the step S30 includes the following sub-steps:
and S31, performing gain adjustment processing on the first audio signal and the initial human voice signal to obtain a first audio signal after gain and the initial human voice signal after gain.
In order to amplify the first audio signal and the initial human voice signal so that the output audio signal meets the requirement of karaoke, the first audio signal and the initial human voice signal need to be subjected to gain adjustment processing.
With reference to fig. 2, taking 4 initial voice signals as an example, the initial voice signals V20, V21, V22, V23 and the audio file V11 are subjected to gain adjustment, so as to sequentially generate the initial voice signals V200, V210, V220, V230 after gain and the first audio signal V110 after gain.
And S32, performing sound mixing processing on the first audio signal after the gain and the initial human voice signal after the gain to obtain a target audio signal.
And S40, outputting the target audio signal.
The current K singing system needs a mobile terminal and an additional microphone system for supporting, a receiver of the mobile terminal is used for collecting voice, then the voice is sent to the microphone system through Bluetooth or NFC, the voice and music of the mobile terminal are processed by the microphone system to generate a third audio signal, and the third audio signal is sent to a vehicle machine in an FM mode to realize the function of K singing. However, the initial voice is transmitted in the FM mode after being transmitted by bluetooth and the like, the distortion is serious, and the initial voice signal of the embodiment is not subjected to redundant modulation, so that the high-quality karaoke effect is ensured.
In a certain embodiment, the vehicle-mounted intelligent internet terminal further comprises a power amplifier and a loudspeaker, wherein the power amplifier is used for amplifying the output target audio signal, and the loudspeaker is used for converting the amplified target audio signal into an acoustic signal, so that a user can hear the audio-mixed target audio signal, and the vehicle-mounted K song function is realized.
This embodiment is through predetermined KTV control strategy, at first carry out the voice to initial audio signal and restrain the processing, obtain the first audio signal who is used for accompanying, when the user need carry out the KTV operation in the car, through picking up car internal environment audio signal and carry out echo cancellation and voice positioning and handle, obtain at least one initial voice signal, then carry out the sound modulation to first audio signal and initial voice signal, obtain the target audio signal of audio mixing, output target audio signal at last. Therefore, the invention utilizes the existing software and hardware resources of the vehicle-mounted intelligent network terminal, such as a microphone, a multimedia player, a DSP audio processor, a loudspeaker and the like, and does not need to utilize an additional singing K microphone system or a mobile terminal, thereby not only realizing the function of high-quality K songs in the vehicle, but also realizing the function of simultaneously K songs by a plurality of people in the vehicle, and greatly improving the vehicle using experience.
Referring to fig. 5, in an embodiment, step S30 further includes:
and S33, performing sound quality optimization processing on the target audio signal.
The tone quality optimization processing includes modulating the volume, sound effect, tone color and the like of the input audio signal. The tone quality optimization processing is carried out on the target audio signal, and the target audio signal can be modified, so that the output target audio signal is more audible, and good karaoke experience is provided.
In a certain embodiment, on-vehicle intelligent networking terminal still includes DSP audio adjuster, and DSP audio adjuster is used for carrying out tone quality optimization to target audio signal to make the target audio signal of output better listen, thereby provide good K and sing and experience.
Please continue to combine fig. 2, taking the 4 people in the car singing at the same time as singing K as an example, the initial human voice signals V200, V210, V220, V230 after the gain and the first audio signal V110 after the gain are input to the DSP audio adjuster, the DSP audio adjuster modulates the audio, the timbre, etc. of the initial human voice signals V200, V210, V220, V230 and the first audio signal V110 after the gain to generate the mixed audio signal V300, and the mixed audio signal V300 is amplified by the power amplifier to generate the target audio signal V400, so as to directly push the speaker to sound.
Referring to fig. 6, in one embodiment, before the step S20 of picking up the audio signal of the environment in the vehicle, the method further includes:
and S60, judging whether the Karaoke mode is triggered or not.
If yes, triggering the function of picking up the environment audio signal in the vehicle according to the Karaoke mode.
The karaoke mode comprises parameters such as a human voice suppression ratio, gain adjustment, sound effect modulation and the like. The user can trigger the karaoke mode through the intelligent internet terminal display according to the user requirement, and the default karaoke mode of the system can be changed on the intelligent internet terminal display. When the vehicle-mounted intelligent internet terminal detects that the Karaoke mode is triggered, the function of S20 is triggered according to the current Karaoke mode. And when the vehicle-mounted intelligent networking terminal detects that the Karaoke mode is not triggered, the function of S20 is not triggered. So, the user can select the function of singing according to the demand in the car, also can set up corresponding K and sing the mode according to the K custom of singing of oneself, and the K sings in the car and experiences well.
In one embodiment, a KTV control application program is also preset in the vehicle-mounted intelligent internet terminal and serves as a desktop application for providing interaction for entering and exiting a Karaoke mode, setting a human voice suppression ratio, adjusting gain and setting audio effect of audio for a user.
Compared with the prior art that the lyrics of the K song can only be displayed on the mobile terminal and cannot be synchronized to the screen of the vehicle-mounted multimedia host because the current K song system needs the support of the mobile terminal, the KTV control application program in the embodiment synchronizes the multimedia player and the display, so that the synchronization of the vehicle-mounted lyrics is realized, and the vehicle-mounted K song experience is further improved.

Wherein the ambient audio signal comprises a first audio signal, a human voice signal and a noise signal.
The current K singing system needs a mobile terminal and an additional microphone system for supporting, a receiver of the mobile terminal is used for collecting voice, then the voice is sent to the microphone system through Bluetooth or NFC, then the voice and music of the mobile terminal are processed by the microphone system to generate a third audio signal, and the third audio signal is sent to a vehicle machine in an FM mode to realize the function of K singing. However, when FM channels conflict, the karaoke system cannot realize 2-or multi-person chorus. And this embodiment need not to adopt the FM mode to send to the car machine, does not have the condition of FM channel conflict, has realized the function of many people K singing simultaneously.
Specifically, when picking up sounds, in addition to the user's voice, the accompaniment and noise played in the car are also picked up. Therefore, by performing echo cancellation on the in-vehicle environment audio signal, noise and echo can be cancelled, and then by the human localization processing, for example, distinguishing whether the sound is emitted by the main driver, the sub-driver or the rear row, the sound source can be determined. Thus, a relatively pure initial human voice signal is obtained.
When multiple persons simultaneously sing K exist in the vehicle, the initial personal sound signals of all the members in the vehicle can be obtained by processing the environment audio signals in the vehicle. Referring to fig. 2, assuming that 4 members in the vehicle are in karaoke at the same time, step S20 may output 4 initial vocal signals, i.e., initial vocal signals V20, V21, V22, and V23, respectively.
Referring to fig. 8, in one embodiment, the initial human voice signal obtaining module 21 includes an environmental audio signal pickup module 211, an echo cancellation processing module 212, and a human voice positioning processing module 213.
The environment audio signal pickup module 211 is used for picking up an environment audio signal in the vehicle.
The echo cancellation processing module 212 is configured to perform echo cancellation processing on the environmental audio signal according to a preset echo cancellation algorithm.
Among them, echo cancellation algorithms include an echo suppression (acoustic echo suppression) algorithm and an acoustic echo cancellation (acoustic echo cancellation) algorithm.
The echo suppression algorithm was an earlier echo control algorithm. Echo suppression is a non-linear echo cancellation that compares the level of sound intended to be played by a loudspeaker with the level of sound currently picked up by a microphone by a simple comparator, and if the former is above a certain threshold, then it is allowed to pass to the loudspeaker, and the microphone is turned off to prevent it from picking up the sound played by the loudspeaker and causing a far-end echo. If the sound level picked up by the microphone is above a certain threshold, the loudspeaker is disabled for echo cancellation purposes.
Acoustic echo cancellation Algorithms (AEC) are based on the correlation of the loudspeaker signal with the multipath echoes it generates, creating a speech model of the far-end signal (s (n)), using it to estimate the echo (e' (n)), and continuously modifying the coefficients of the filter so that the estimate more closely approximates the true echo (e (n)). Then, the echo estimation value is subtracted from the input signal of the microphone, so as to achieve the purpose of eliminating the echo.
The voice positioning processing module 213 is configured to perform voice positioning processing on the environmental audio signal after the echo cancellation according to a preset sound source positioning algorithm to obtain at least one initial voice signal.
The sound source positioning algorithm includes a Time-Delay Estimation (TDE) algorithm and a generalized cross-correlation (GCC) Time-Delay Estimation algorithm.
Sound source localization is the spatial arrangement of microphones in a geometric array to receive sound field information of the noise of an object, and the azimuth information of the object is determined by detecting or calculating the time delay of the signal measured by each microphone. In this example, the positions of the multiple microphones may be determined.
The time delay estimation algorithm utilizes time delay estimation caused by different signal propagation distances among sensors or sensor arrays to finish combined direction finding and distance measuring of a target; if the time delay value existing between the arrival of the sound wave at each array element can be accurately estimated, and the parameter estimation quantity of the target position can be calculated according to the geometric relationship of the microphone array arrangement.
The GCC method is a conventional TDE method. Since there is a certain correlation between signals from the same sound source, the TDE value can be estimated by calculating the correlation function between signals received by different microphones. However, in practical environments, due to the influence of noise and reverberation, the maximum peak of the correlation function is weakened and sometimes multiple peaks occur, which make the actual peak detection difficult. The GCC method weights the signal in the power spectrum to emphasize the relevant signal portion and suppress the noise-disturbed portion, so as to make the peak value of the correlation function at the time delay more prominent.
The target audio signal obtaining module 22 is configured to perform sound modulation on the first audio signal and the initial human voice signal to obtain a target audio signal.
Mixing (Audio Mixing) is a step in music production, where sound from multiple sources is integrated into a Stereo (Stereo) or Mono (Mono) soundtrack. These original sound signals may come from different musical instruments, voices or orchestras, respectively, which are recorded in live performance (live) or recording rooms. In the process of sound mixing, the frequency, dynamics, tone quality, positioning, reverberation and sound field of each individual original signal are independently adjusted to optimize each sound track, and then the sound tracks are superposed on a final finished product. In this embodiment, the first audio signal and the initial human voice signal are subjected to sound modulation, so as to obtain a mixed target audio signal.
The Mixing device can be a synthesizer (Sound Module), an audio Processor (Signal Processor) and a Mixing Console (Mixing Console), or Mixing software, so as to complete complex Mixing operation. In this example, by processing with a preset mixing algorithm, when the first audio signal and the initial human voice signal are input to the mixing device or mixing software, mixing processing is automatically performed, and a mixed target audio signal is output. The mixing step includes, but is not limited to, rail aligning, modifying, noise reduction, excitation, tooth sound removal, equalization, and compression.
Referring to fig. 9, in one embodiment, the target audio signal obtaining module 22 includes a gain adjustment processing module 221 and a mixing processing module 222.
The gain adjustment processing module 221 is configured to perform gain adjustment processing on the first audio signal and the initial human voice signal to obtain a first audio signal after gain and a initial human voice signal after gain.
In order to amplify the first audio signal and the initial human voice signal so that the output audio signal meets the requirement of karaoke, the first audio signal and the initial human voice signal need to be subjected to gain adjustment processing.
With reference to fig. 2, taking 4 initial voice signals as an example, the initial voice signals V20, V21, V22, V23 and the audio file V11 are subjected to gain adjustment, so as to sequentially generate the initial voice signals V200, V210, V220, V230 after gain and the first audio signal V110 after gain.
The audio mixing processing module 222 is configured to perform audio mixing processing on the first audio signal after the gain and the initial human voice signal after the gain to obtain a target audio signal.
The target audio signal output module 23 is configured to output a target audio signal.
The current K singing system needs a mobile terminal and an additional microphone system for supporting, a receiver of the mobile terminal is used for collecting voice, then the voice is sent to the microphone system through Bluetooth or NFC, the voice and music of the mobile terminal are processed by the microphone system to generate a third audio signal, and the third audio signal is sent to a vehicle machine in an FM mode to realize the function of K singing. However, the initial voice is transmitted in the FM mode after being transmitted by bluetooth and the like, the distortion is serious, and the initial voice signal of the embodiment is not subjected to redundant modulation, so that the high-quality karaoke effect is ensured.
This embodiment is through predetermined KTV control strategy, at first carry out the voice to initial audio signal and restrain the processing, obtain the first audio signal who is used for accompanying, when the user need carry out the KTV operation in the car, through picking up car internal environment audio signal and carry out echo cancellation and voice positioning and handle, obtain at least one initial voice signal, then carry out the sound modulation to first audio signal and initial voice signal, obtain the target audio signal of audio mixing, output target audio signal at last. Therefore, the invention utilizes the existing software and hardware resources of the vehicle-mounted intelligent network terminal, such as a microphone, a multimedia player, a DSP audio processor, a loudspeaker and the like, and does not need to utilize an additional singing K microphone system or a mobile terminal, thereby not only realizing the function of high-quality K songs in the vehicle, but also realizing the function of simultaneously K songs by a plurality of people in the vehicle, and greatly improving the vehicle using experience.
Referring to fig. 10, in one embodiment, the vehicle-mounted KTV control apparatus further includes a determining module 24, configured to determine whether the karaoke mode is triggered;

The karaoke mode comprises parameters such as a human voice suppression ratio, gain adjustment, sound effect modulation and the like. The user can trigger the karaoke mode through the intelligent internet terminal display according to the user requirement, and the default karaoke mode of the system can be changed on the intelligent internet terminal display. When the vehicle-mounted intelligent internet terminal detects that the Karaoke mode is triggered, the function of the step S20 is triggered according to the current Karaoke mode. And when the vehicle-mounted intelligent internet terminal detects that the Karaoke mode is not triggered, the function of the step S20 is not triggered. So, the user can select the function of singing according to the demand in the car, also can set up corresponding K and sing the mode according to the K custom of singing of oneself, and the K sings in the car and experiences well.
