Abstract

The application discloses a monaural speech intelligibility prediction unit, a hearing aid and a binaural hearing system, wherein the monaural speech intelligibility prediction unit is adapted to receive a target speech signal comprising a clean or noisy and / or processed version The information signal is configured to provide a speech intelligibility prediction value of the information signal as an output, and the speech intelligibility prediction unit includes: an input unit; an envelope extraction unit; a time-frequency segment separation unit; a segment estimation unit; Intelligibility calculation unit; final speech intelligibility calculation unit. The present invention is applicable to monaural, non-intrusive intelligibility prediction of noisy / processed speech signals; binaural, non-intrusive intelligibility prediction of noisy / processed speech signals; or monaural of noisy speech signals and binaural intelligibility enhancement.

Description

technical field [0001] This application relates to the field of hearing aids. The invention particularly relates to a signal processing method for predicting the intelligibility of speech, such as an index that is highly correlated with a portion of an utterance that a normal listener (a group of listeners with similar hearing curves) can understand from some speech material. Background technique [0002] The intelligibility is reduced for speech signals that are distorted eg by noise or reverberation and which may have passed through some signal processing means such as hearing aids. Therefore, there is a need for a solution to predict the intelligibility of such speech signals in order to take corresponding measures to improve the listening quality of the user. SUMMARY OF THE INVENTION [0003] The present invention provides solutions to the following problems: [0004] 1. Monoaural, non-invasive intelligibility prediction of noisy / processed speech signals; [0005] 2...
