| 实时识别中语音的时域─频域─能量表示 |
| The time─frequency─energy representation off speech signal in real-time recognition |
| |
| 中文摘要: |
| 本文提出了语音信号的一种时域─频域─能量表示，并给出了算法，可用于孤立词语音识别．这种时域─频域─能量表示有两个特点：基于短时能量梯度的非线性时间规正，可保留语音信号频域的过渡特性，丢掉其稳态特性；计算量小，适于实时应用． |
| 英文摘要: |
| A time- frequency- energy representation of speech signal and it s algorithm are introduced to isolated-word speech recognition. It can be characterized by two aspects: (1) non-linear time normalization, based on the gradients of short-time energy in a specific number of frequency bands, retains the transient portions and ignores the steady-state portions of speech signal in frequency domain. (2) real-time implementation due to low computational load. |
