HEARING AID AND METHOD OF ENHANCING SPEECH OUTPUT IN REAL TIME

摘要

A method for enhancing speech output in real time is used in a hearing aid device. The input speech is divided into multiple audio segments first. Then each audio segment is analyzed for its attribute: high frequency, low frequency, or soundless. Low frequency segments are outputted without undergoing frequency processing. High frequency segments are outputted after undergoing frequency processing. All or some of the soundless segments are deleted without being outputted. The deletion of soundless segments can reduce the delay caused by the frequency processing of the high frequency segments.

1. A method of enhancing speech output in real time, used in a hearing aid device, the method comprising:
receiving an input speech; dividing the input speech into a plurality of audio segments; searching for at least two audio segments with different attributes from the plurality of audio segments, including:
a soundless segment, wherein a sound energy of the soundless segment is lower than a sound energy threshold; anda non-soundless segment, wherein a sound energy of the non-soundless segment is higher than a sound energy threshold; and outputting some of the plurality of audio segments, wherein:
all or some of the non-soundless segments undergo frequency processing and then all of the non-soundless segments are outputted; andall or some of the soundless segments are deleted and are not outputted; whereby a delay caused by performing frequency processing on all or some of the non-soundless segments can be reduced or eliminated by deleting all or some of the soundless segments.
