人耳听觉仿声机理的研究

STUDITS ON IMITATING SOUND MEANISM OF SENSE OF HEARING OF HUMAN EAR

本文从生物物理学的角度研究了人耳听分析器的机械变压作用及换能作用,阐述了人耳的语声从机械频率分析到生物电分析的过程。对目前语音识别中几种特征参数的识别战略及算法进行了实验对比,指出了目前语音识别模型存在的问题及这几种参数识别的局限性,发掘的潜力及与人耳听觉的差距。

In this article the mechanical transformation and transduction of hearing analytical organs of human ear are studied from the angle of biological physics. It expounds the process of speech sounds of human ear from mechanical frequency analysis to bioelectric analysis. It carries out experimental contrast on recognozable strategy and algorithm of several characteris-tic parameters in speech recognition at present, and indicates the existing questions in models of speech recognition, the limitations of recognition of parameters, the excavated potentialities,and the disparity between the sense of hearing human ear and the of human intelligence.
