Detailed Description
In order to make the technical content of the present invention more comprehensible, preferred embodiments are described below.
Fig. 1 is a schematic diagram of a hearing aid according to the present invention.
As shown in fig. 1, the hearing aid 10 of the present invention includes a microphone 11, a voice processing module 12, a voice output adjusting module 13, and a voice player 14. The microphone 11 is used for receiving an input voice. The voice player 14 is a speaker or an earphone for outputting an output voice. The voice processing module 12 can be an amplifier electrically connected to the microphone 11, the voice output adjusting module 13 and the voice player 14. The voice processing module 12 is used for receiving the input voice from the microphone 11 and then changing the output energy of the input voice to form the output voice. The speech processing module 12 can be used to adjust the sound output energy of at least N orders, where the sound output energy of the nth order is larger than the sound output energy of the nth-1 order, and in an embodiment of the present invention, 2 ≦ N, N ≧ 3, but less than 10000. However, the present invention is not limited to the upper or lower limit of N here.
When the voice processing module 12 adjusts the nth order sound output energy, the voice output adjusting module 13 also reduces at least a portion of the frequency of the input voice. And when the speech processing module 12 adjusts the sound output energy of the (N-1) th order, the speech output adjusting module 13 also reduces at least a part of the frequency of the input speech, and the degree of reducing at least a part of the frequency of the input speech when adjusting the sound output energy of the (N) th order is greater than the degree of reducing at least a part of the frequency of the input speech when adjusting the sound output energy of the (N-1) th order. The voice output adjusting module 13 may perform m-stage adjustment on the frequency of at least a portion of the input voice, where n ≧ m. It should be noted that the voice output adjusting module 13 adjusts the frequency of at least a part of the input voice to the high-frequency consonants in the input voice, but the voice output adjusting module 13 does not adjust the frequency of the monaural frequency in the input voice.
In one embodiment of the present invention, a phonetic symbol is used for explanation. For ZhuYin symbol, its vowel is "ㄧ、ㄨ、ㄩ、ㄚ、ㄛ、ㄜ、ㄝ、ㄞ、ㄟ、ㄠ、ㄡ、ㄢ、ㄣ、ㄤ、ㄥ、ㄦ", and its sub-tone is "ㄅ、ㄆ、ㄇ、ㄈ、ㄉ、ㄊ、ㄋ、ㄌ、ㄍ、ㄎ、ㄏ、ㄐ、ㄑ、ㄒ、ㄓ、ㄔ、ㄕ、ㄗ、ㄘ、ㄙ". Therefore, the voice output adjustment module 13 will first find out the consonants and vowels in the input voice. For example, when the sound of "ㄙㄠ" is uttered, the voice output adjustment module 13 can know that the first syllable is "ㄙ" and the second syllable is "ㄠ", and the voice output adjustment module 13 adjusts the frequency of the first syllable "ㄙ".
Therefore, in one embodiment of the present invention, the relationship between the output energy and the frequency of the speech is shown as the following table:
the speech processing module 12 adjusts the output energy of the input speech from 5dB to 10dB when the 1 st order volume is to be adjusted to the 2 nd order volume, and the speech processing module 12 adjusts the output energy of the input speech from 15dB to 20dB when the 3 rd order volume is to be adjusted to the 4 th order volume. In this way, the volume of the output voice can be adjusted in stages, and the invention does not limit the volume to be adjusted to 11 th level. While adjusting the volume, the voice output adjusting module 13 also reduces the frequency of at least a portion of the input voice. For example, when the volume is adjusted to the 3 rd order volume, the voice output adjusting module 13 shifts at least a part of the frequency blocks of the input voice so that the lowest frequency part of the energy distribution block of the input voice is aligned to 5100Hz, and when the volume is adjusted to the 4 th order volume, the voice output adjusting module 13 aligns the lowest frequency part of the energy distribution block of the input voice to 4800 Hz. The amplitude of the frequency down-regulation of the input voice is larger than that of the 3 rd order volume down-regulation at the 4 th order volume, the amplitude of the frequency down-regulation of the input voice is maximum until the maximum 11 th order volume, and the frequency of the lowest frequency part is required to be shifted to 1000 Hz. And the stage that the voice output adjusting module 13 will adjust is smaller than the stage that the volume can be adjusted. Taking the previous look-up table as an example, the voice output adjusting module 13 does not adjust down the frequency of the input voice at the 1 st and 2 nd level volumes. It is also noted that the present invention is not limited to the look-up table of the front row.
It should be noted that, besides being configured as a hardware device, a software program, a firmware, or a combination thereof, each of the above modules may also be configured by a circuit loop or other suitable types; moreover, the modules may be arranged in a combined manner, as well as in a single manner. In addition, the present embodiment only illustrates the preferred embodiments of the present invention, and all possible combinations and modifications are not described in detail to avoid redundancy. However, one of ordinary skill in the art should appreciate that each of the modules or assemblies described above is not necessarily required. And other well-known modules or components may be included for performing the invention in more detail. Each module or component may be omitted or modified as desired, and no other module or component may necessarily exist between any two modules.
Next, please refer to fig. 2, which is a flowchart illustrating a method for adjusting output voice of a hearing aid according to the present invention. It should be noted that although the method of adjusting the output voice of the hearing aid of the present invention is described below by taking the hearing aid 10 as an example, the method of adjusting the output voice of the hearing aid of the present invention is not limited to the hearing aid 10 having the same configuration as described above.
First the hearing aid 10 receives an input speech using the microphone 11.
Then, step 202 is performed: the output energy of the input speech is changed.
The voice processing module 12 receives the input voice from the microphone 11 and adjusts at least the N-th order voice output energy, wherein the N-th order voice output energy is larger than the N-1 th order voice output energy.
Then, step 203 is performed: and reducing the frequency of at least part of the input speech to form an output speech.
Then, the voice output adjusting module 13 also reduces the frequency of at least part of the input voice. And when the voice processing module 12 adjusts the sound output energy of the (N-1) th order, the voice output adjusting module 13 also reduces at least a part of the frequency of the input voice, and the degree of reducing at least a part of the frequency of the input voice when adjusting the sound output energy of the (N) th order is greater than the degree of reducing at least a part of the frequency of the input voice when adjusting the sound output energy of the (N-1) th order. For example, when the volume is adjusted to the 3 rd order volume, the voice output adjustment module 13 shifts at least a part of the frequency blocks of the input voice to align the lowest frequency part of the energy distribution block of the input voice to 5100Hz, and when the volume is adjusted to the 4 th order volume, the voice output adjustment module 13 aligns the lowest frequency part of the energy distribution block of the input voice to 4800 Hz. In this way, the voice processing module 12 and the voice output adjusting module 13 can adjust the output voice together.
Finally, step 204 is performed: the output speech is output.
Finally, the hearing aid 10 outputs the output speech by means of the speech player 14 for use by the hearing impaired or the elderly.
It should be noted that the method for adjusting the output voice of the hearing aid of the present invention is not limited to the above-mentioned sequence of steps, and the sequence of steps can be changed as long as the objective of the present invention is achieved.
As can be seen from the above description of the hearing aid 10 and the method for adjusting the output voice of the hearing aid, the hearing aid 10 adjusts the volume and also adjusts the frequency synchronously. Therefore, the hearing-impaired or old users can hear clear voice under the condition of no matter the output energy.
It should be noted that the above-mentioned embodiments are only examples, and are not limited to the examples. For example, those skilled in the art will recognize that the invention may be practiced without these specific details.
