This paper introduced a new method to synthesis Chinese speech. Using Wavelet Transform to detect the Glottal Closure Instant (GCI), proposed pitch-synchronization and sample selection LP analysis based on the GCI information, the obtained parameters would be saved in the speech database. The duration and fundamental frequency can be changed by adjusted the speech parameters. The speech parameters obtained by proposed method are more accuracy than the traditional method does, and the synthesized speech is clear and natural. on the other hand, the storage of the speech database is highly decreased, so the proposed method is suitable for the mini-micro computer system.

The decomposition algorithm of the characteristic waveform interpolation(WI) speech coding is investigated.A novel WI speech coding algorithm based on pitch synchronization is proposed. In the new speech coding algorithm, the quantization of the characteristic waveform is the variable dimension vector quantization (VDVQ ). The decoding speech of 2.4 kb/s shows it can deliver decoded speech with high communication quality

研究了在特征波形语音编码算法中的特征波形分解算法,提出了一种基于基音同步的特征波形内插语音编码算法。特征波形的量化采用变维矢量量化(VDVQ)。通过实现的2.4kb/s的语音质量表明,这种语音压缩算法在低码率时能得到高通信质量的重建语音。

This paper focuses on the design of high quality speech coding, with variable rate at 0.75-5.4kb/s. The new algorithm classifies input speech signals as noise, unvoiced speech, transitional speech and voiced speech, and it uses different codebooks as excited impulses according to different types of speech frames. Especially, an embedded splitting vector quantization method based on pitch synchronization to synthesize voiced speech is proposed. The speech can be recovered very well at low bit rate by making...

This paper focuses on the design of high quality speech coding, with variable rate at 0.75-5.4kb/s. The new algorithm classifies input speech signals as noise, unvoiced speech, transitional speech and voiced speech, and it uses different codebooks as excited impulses according to different types of speech frames. Especially, an embedded splitting vector quantization method based on pitch synchronization to synthesize voiced speech is proposed. The speech can be recovered very well at low bit rate by making use of the pitch periodicity for voiced speech frames. This new algorithm can overcome the disadvantage of CELP whose recovered speech quality will degrade quickly when the bit-rate is below 4kb/s because the codebook size is too small. The informal listening test results show that the subject quality of the algorithm exceeds that of QCELP while the average bit rate of the algorithm is only about 2kb/s, which is much lower than that of QCELP whose average bit, rate is about 5kb/s. This new speech coding algorithm is therefore very apt to CDMA mobile communication systems.

该文提出了一种码率为 0.75-5.4kb/s可变速率的高质量语音编码讲法。该算法对CELP的激励进行了改进,根据语音的特征把语音分成4类,不同类型的语音采用不同的激励码本。特别是对于浊音,提出了一种基于基音同步的嵌入分裂式激励码本,该码本利用浊音具有准周期性的特点,使该算法在很低的码率下就可很好地恢复浊音信号,克服了CELP在4kb/s速率以下因码本尺寸小而导致合成语音质量差的缺点。经非正式听音测试,它的主观质量超过了1~8kb/s的可变速率QCELP系统,并且平均速率大约只有2kb/s,比QCELP的5kb/s平均速率低了很多、非常适用于 CDMA移动通信系统。
