一种全息声元语音编码方法

Speech Encoding-Holography Sound Cell Encoding

引入了一种新的语音编码方法——全息声元编码,该编码技术将语音节分解为一个声元序列,其中每一个声元均包含原始语音节的主要信息,而全体声元则完全包含原始语音节的全部信息。实验表明,该编码方法具有无浮点运算、运算量小、容错能力强等优点,即使在随机损失75%编码数据的情况下也能很好地重建原始语音信号。

A new speech coding method called the holography sound cell encoding is introduced based on audio holography cell transformation. By the new method, speech signal is transformed into a series of holography cells compressed in time axis and similar to each other in waveform. Experimental results show that the method has non-floating-point calculation, small computation and strong fault-tolerant. Even 75% audio holography cells are lost in transmitting link, the original speech signal is reconstructed with a good quality.
