Mp3 compress ratio can reach 1:12 mainly because of its lossy compress method depended on psycho acoustic model.
MP3编码之所以能达到1:12的压缩比例,主要在于它是依据心理声学模型的有损压缩。

These two product items are the linguistic model and acoustic model.
这两个乘积项分别是语言模型和声学模型。
It is not a practical grammar by any means-when building an acoustic model from grammars as small as this, you soon run into problems regarding insufficient samples.
无论如何它不是一个实际的文法—通过这么小的文法构建语音模型时，您很快就会遇到样例不够的问题。
We can categorize many state-of-the-art environment compensation approaches into two classes: the front-end and the back-end (acoustic model) processing approaches.
目前的一些鲁棒性环境补偿方法具体可分为两大类：前端处理方法和后端（声学模型）处理方法。
