Further, said apparatus also can have following characteristics: the background sound in the described background sound storehouse is provided by producer, is perhaps recorded voluntarily or is downloaded by the user.
Further, said apparatus also can have following characteristics: the background sound in the described background sound storehouse is the sound of music or true environment sound or the Nature.
Another technical problem that the present invention will solve provides a kind of method of speech processing, can remove background noise, the stack background sound.
In order to solve the problems of the technologies described above, the present invention provides a kind of method of the background sound that superposes again on communication terminal, may further comprise the steps:
(a) during the communication terminal communication, microphone receives intelligencer's the voice and the noise in current place, exports the voice signal that has noise;
(b) this signal is carried out Filtering Processing after going the background noise device to receive the signal of microphone output, obtain pure voice signal;
(c) the background sound synthesizer synthesizes the background sound signal of the described pure voice signal that receives and the output of background sound storehouse, generates the voice signal that has background sound.
Further, said method also can have following characteristics: in described step (a) before, the user is in advance by the background sound in the selected background sound storehouse of communication terminal.
Further, said method also can have following characteristics: the background sound in the described background sound storehouse is provided by producer, is perhaps recorded voluntarily or is downloaded by the user.
Further, said method also can have following characteristics: the background sound in the described background sound storehouse is the sound of music or true environment sound or the Nature.
Further, said method also can have following characteristics: Filtering Processing described in the described step (b) is for earlier filtering the outer noise of speech frequency by band pass filter, filters noise in the speech frequency by self adaptation white noise filter again.
Adopt device and method of the present invention can remove the mobile communication terminal device background noise, improve communication quality, the background sound of stack can be the background music that increases temperament and interest.
Description of drawings
Fig. 1 is present communication terminal speech processes transmission course schematic diagram;
Fig. 2 is the communicating terminal speech processes transmission course schematic diagram that adopts voice processing apparatus in the present embodiment.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, between microphone that has communication terminal now and communication device, increase by a voice processing apparatus.The voice signal of band noise converts the signal of telecommunication to by microphone, sends to communication device by the voice processing apparatus filter out background noise and after being superimposed with the background sound that sets in advance, and imports mobile communcations system into by communication device again, and then sends to the recipient again.
Voice processing apparatus includes background noise device, background sound storehouse and background sound synthesizer.Go the voice signal of band noise that the background noise device receives microphone output through the pure voice signal of output after the filtering, the background sound of this signal in the background sound storehouse that the user selectes is synthetic through the background sound synthesizer, generates the voice signal of band background sound.
Go the background sound filter to be used for removing the noise of the voice signal of being with noise, comprise a band pass filter and a self adaptation white noise filter, band pass filter receives the signal of telecommunication that comprises voice, background sound that microphone sends, through removing the outer noise of speech frequency after the filtering, the voice signal of output is removed the interior noise of speech frequency by self adaptation white noise filter again, exports pure voice signal.Reach the removal background sound, reduce the purpose of noise.The present invention also can adopt other noise filtering device.
Background sound is selected for the user in the background sound storehouse, the background sound that the user can select the background sound storehouse to provide, and the background sound storehouse can be provided by producer, also can be put into or be downloaded by the sound that the user records expectation voluntarily.The background sound in this background sound storehouse can be the real ambient sound in music, certain place, also can be the sound of the Nature.The user selectes the background sound in the background sound storehouse in advance before using communication terminal to carry out communication, the user also can not do selection, defaults to no background sound.
The background sound synthesizer is used for the synthetic pure voice signal of background noise device output and the background sound signal in background sound storehouse of going, and the voice signal that two-way is imported superposes, and the synthetic speech signal of output is passed to communication device.This background sound synthesizer can use common phonosynthesis device.
Correspondingly, the treatment step of present embodiment method is as follows:
(a) user is by the background sound in the in advance selected background sound storehouse of communication terminal;
(b) during the communication terminal communication, as the input signal of microphone, the background noise device is removed in the signal of telecommunication input after microphone will be changed jointly for intelligencer's the voice and the noise in current place;
(c) go the background noise device to receive this signal of telecommunication after, this signal is carried out Filtering Processing, earlier filter the outer noise of speech frequency by band pass filter, filter noise in the speech frequency by self adaptation white noise filter again, obtain pure voice signal;
(d) the selected in advance background sound signal of this pure voice signal and user together is input to the background sound synthesizer, after synthetic, obtains having the voice signal of background sound;
(e) these voice after synthetic send the recipient to by communication device, communication system, the sound after the voice that the recipient hears the speaker synthesize with the background sound of expectation.
Voice processing apparatus of the present invention does not require mobile communcations system, all can use in existing mobile communcations system.
