The invention relates to a voice data processing method and a binaural hearing aid. The method is applied to the binaural hearing aid, the binaural hearing aid comprises a first hearing aid and a second hearing aid, and the method comprises the following steps: respectively acquiring voice data acquired by the first hearing aid and the second hearing aid, extracting voiceprint features in the voice data under the condition of judging that potential self-talking voice exists in the voice data, the voiceprint features are compared with stored standard voiceprint features of the user, a comparison result is obtained, the standard voiceprint features are obtained by processing voice sample data of the user, and the voice sample data comprise near-talking voice data collected by a first hearing aid close to the mouth of the user; and if the comparison result shows that the self-talking voice exists in the voice data, performing enhancement processing on the voice data. By adopting the method, more accurate self-talking voice detection can be realized.

The application provides a method and device for improving sound source positioning accuracy of a binaural hearing aid, which is applied to the binaural hearing aid, and the method comprises the following steps: acquiring a first frequency signal and a second frequency signal, and recording intensity information and respective acquisition time stamps of the first frequency signal and the second frequency signal, wherein the first frequency signal and the second frequency signal are the same specific frequency signal with different acquisition positions; if the acquisition time stamp of the first frequency signal is synchronous or earlier than that of the second frequency signal, when the binaural hearing aid is affected by a head shadow effect, the intensity information difference between the first frequency signal and the second frequency signal and the time difference of the acquisition time stamps are calculated, the analog distance of the specific frequency signal affected by the head shadow effect on a propagation path is deduced, the intensity information of the analog frequency signal and the analog acquisition time stamp are calculated through the difference of sound wave propagation speeds in different media, and available frequency information can be generated.

This invention patent provides a sound coordination processing method and apparatus for binaural hearing aids. The binaural hearing aid has two audio acquisition devices located on either side of the head, and the two audio acquisition devices are communicatively connected. The method includes: the two audio acquisition devices synchronously acquiring sounds from the surrounding environment and adding timestamps to the sounds; parsing the sounds into multiple sound signals with different audio characteristics, the sound signals excluding noise signals; adaptively adjusting the sound signals according to the order in which they are acquired; merging the adaptively adjusted sound signals into an output signal; and recording the sound signal characteristics acquired by one hearing aid within a certain time domain so that when the other hearing aid acquires the sound signal with the same characteristics, there is no need for secondary filtering of that sound signal.

The present application describes a method for processing voice data for a binaural hearing aid. The binaural hearing aid may comprise a first hearing aid and a second hearing aid. The method may comprise acquiring voice data collected by the first hearing aid and the second hearing aid respectively; and extracting a voiceprint feature from the voice data based on determining that potential self-talk voice is in the voice data. The method may further comprise determining, based on voice sample data of a user, standard voiceprint feature associated with the user. In addition, the method may further comprise comparing the voiceprint feature with the standard voiceprint feature to obtain a comparison result; and enhancing the voice data based on determining that the comparison result indicates self-talk voice in the voice data.

A binaural hearing aid system comprises left and right hearing instruments each comprising a BTE-part comprising a housing configured to be located at or behind an outer ear of the user and an acceleration sensor configured to measure acceleration in at least two directions relative to the housing of the BTE-part and to provide acceleration data indicative thereof. A first one of the left and right hearing instruments comprises a transmitter configured to transmit said acceleration data to the other hearing instrument, and the other hearing instrument comprises a receiver for receiving said acceleration data from the first one of the hearing instruments. The other hearing instrument further comprises a controller for detecting whether or not the left and right hearing instruments are correctly mounted in dependence of a similarity measure between said acceleration data provided by the left and right hearing instruments. A method of operating a binaural hearing aid system is further disclosed.
