feature words extraction

基本解释

A two-layer neural network for humming feature extraction is proposed for note segmentation and note recognition, when users sing consecutively with arbitrary words.
针对用户以任意字词连续哼唱的情况下，哼唱特征提取中音符分割、音符识别难度大的问题，提出了一种基于两级神经网络的哼唱特征提取方法。
Isolated words recognition experiment based on DTW shows: this method iso. K. In automatic detection of speech terminal and extraction of speech feature; and achieves very satisfying recognition rate.
实验结果表明：该法在噪声环境下自动检测语音端点和提取语音信号的特征是可行的，获得了很满意的识别率。
