Patent No. EP3961624 (titled "Method For Operating A Hearing Aid Depending On A Speech Signal") was filed by Sivantos PTE on Aug 12, 2021. The application was issued on Sep 25, 2024.
A method for operating a hearing device based on speech quality, where the device records a sound containing a speech signal, converts it into an input audio signal, and generates an output audio signal through signal processing. The processing is controlled by a quantitative measure of speech quality derived from articulatory properties of the speech signal, such as formant precision, consonant dominance, and transition accuracy. This measure is independent of external noise and transmission channel effects, focusing solely on the intrinsic properties of speech production.
