Otherwise, the same procedure as in example 1 was repeated.
Example 3
As shown in fig. 4, the hearing aid further comprises a language translation unit, which is connected to the speech recognition text unit and the text-to-speech unit, and converts speech into text through the speech recognition text unit, and then translates the text into another language text through the language translation unit, and then converts the text into a speech stream suitable for a hearing aid user through the text-to-speech unit. Otherwise, the same procedure as in example 1 was repeated.
The following is a detailed description of the various components of the hearing aid:
first, a microphone, also called a microphone or a microphone, is a transducer that converts a sound signal into an electrical signal. Secondly, the amplifier sound signal is received by the microphone and converted into an electric signal, and the electric signal is sent to a signal processing part of the hearing aid to be processed according to requirements. This part, also called amplifier, may be said to be a core part in the concept of a hearing aid. The main function of a hearing aid is to process sounds that cannot be heard by a hearing-impaired person into audible sounds as needed. The signal processing includes amplification, frequency response adjustment and input-output curve adjustment. These processes may be either analog or digital. And thirdly, the amplified audio signal processed by the receiver is sent to the receiver, and the receiver converts the amplified electric signal into an acoustic signal or mechanical vibration and transmits the acoustic signal or the mechanical vibration into the ear canal. And fourthly, the noise reducer is used for reducing various environmental noises.
And fifthly, the battery hearing aid supplies the required energy by a battery. Batteries convert chemical energy into electrical energy. Depending on the chemically reactive material in the cell, the cell used in the hearing aid may be an oxide cell in which zinc reacts with mercury oxide. The output sound pressure of the hearing aid is limited if the energy of one battery is insufficient.
Sixth, speech recognition character unit
The unit recognizes in real time from the speech stream that the spoken word includes words and sentences, forming a word stream containing words and sentences. If necessary, the unit communicates with the cloud server, and recognition is completed with the assistance of the cloud server.
Seven, word to speech unit
The unit converts a text stream containing words and sentences into speech to form a speech stream. If necessary, the unit communicates with the cloud server, and conversion is completed with the assistance of the cloud server.
Eight, language translation unit
The unit converts a text stream containing words and sentences in one language to a text stream in another language.
Display unit
The unit displays the input text, pictures or videos.
The text is converted into a voice stream suitable for a hearing aid user through the text-to-voice unit, and the method specifically comprises the following steps: and performing adaptation processing on the converted voice according to the hearing loss condition of the user so as to be suitable for the user to listen. The hearing loss of the user can be obtained by performing hearing tests on the user. The hearing test usually obtains the lowest loudness level of sound at different frequencies (typically 8 frequencies between 125Hz and 8000 Hz) that the left and right ears of the subject can feel, which also reflects the hearing loss of the left and right ears of the subject at different frequencies. Hearing aids require adaptation of the input sound to the hearing impairment of the user. Hearing loss of the hearing impaired typically suffers from different levels of loss in different frequency bands, such as 10dB for the 500Hz band and 50dB for the 2000Hz band, so that when the hearing loss is adapted, a 5dB gain is compensated for the 500Hz band and a 30dB gain is compensated for the 2000Hz band.
According to the sound characteristic of a speaking party, the converted voice has the voice characteristic of the communicating party (the specific implementation method is that the voice characteristic of the communicating party is extracted firstly, and then the voice characteristic of the communicating party is added in the voice synthesis link), so that the communication experience of a hearing aid user is improved.
The main body of the hearing aid is a smart phone, and the text stream is displayed on the screen of the smart phone; the voice recognition character unit is realized by the smart phone at the home terminal or by the cloud end matching; the microphone is a built-in microphone or an external microphone of the smart phone; the receiver is an internal loudspeaker or an external earphone of the smart phone.
The main body of the hearing aid is a smart phone, and a hearing test unit is arranged in the smart phone and is used for testing the hearing loss condition of a user and obtaining a hearing loss test result; the condition according to the hearing loss of the user refers to the result according to the hearing loss test.
The invention relates to a using method of a hearing aid, which comprises 2 operation modes, wherein 1 mode is a standard mode M1, namely, sound input in real time through a microphone is subjected to noise reduction processing by a noise reducer and amplified by an amplifier and then is output to a receiver; the other mode is a reproduction mode M2, in which voice input in real time through a microphone is subjected to noise reduction processing by a noise reducer and amplification processing by an amplifier, the voice is recognized into a text stream through a voice recognition text unit, and the text stream is converted into a voice stream through a text-to-speech unit (the sub-mode M2-1 of M2) and output to a receiver or/and the text stream is displayed through a display unit (the sub-mode M2-2 of M2).
The sub-mode M2-1 of the standard mode M1 and the regeneration mode M2 can be switched by a user; the sub-mode M2-2 of the standard mode M1 and the regeneration mode M2 can be activated simultaneously (i.e. in the standard hearing aid mode, the opposite language is recognized as characters to be displayed); the sub-mode M2-1 of the reproduction mode M2 and the sub-mode M2-2 of the reproduction mode M2 can be activated simultaneously (i.e., the language-recognized character of the opposite party is displayed while the language-recognized character of the opposite party is reconverted to a voice stream).
