一种低比特率中文语音信息编码传输技术

Chinese Speech Information Coding for a Low-bit-rate Transmission Technique

研究一种中文语音信息编码技术.通过采用语音小波分析识别处理和语音信息特征编码,包括中文语音小波包分解、语音音素和音节声调识别、口音特征参数提取、语音信息和特征参数组合编码,这种低比特率编码技术理论上可将传输效率提高1倍.

To study a technique on Chinese speech information coding. The low-bit-rate coding technique can double the speech processing with wavelet analysis and recognition, and information coding with speech characteristics, which include wavelet package disassembling, speech phoneme and syllable note recognizing, accent character fetching, speech information and character parameter integrated coding.
