我们认为，描述人类语言的唯一方法不是描述感知本身，而是描述与语音感知研究中获得的实验数据最兼容的人工语音理解系统。为此，建立了一个包含耳蜗的多通道模型作为模拟系统。该模型能够检测到光谱和强度的快速变化。在语音诱导的兴奋模式中检测这种不规则性似乎是语音处理的重要组成部分。在光谱形状处理方面，实验似乎表明，在较低的水平上提取光谱峰，而在较高的水平上，如果峰之间的距离不超过3.0-3.5 Bark，则进行积分。
We believe in our group that the only way to describe human speech is to describe not the perception itself but the artificial speech understanding system that is most compatible with the experimental data obtained in speech perception research. For this purpose a multichannel model comprising the cochlea has been built as an analog system. This model is able to detect quick changes in spectrum and intensity. The detection of such irregularities in the speech-induced excitation pattern seems to be an essential part of speech processing. As for spectrum-shape processing, experiments seem to indicate that spectral peaks are extracted at a lower level, whereas an integration takes place at a higher level if the distance between peaks does not exceed 3.0-3.5 Bark.
