Chapter two was developed the fundamental theorem of speech enhancement, in which the characteristics of speech versus noise, and the model of the speech formation as well, were analyzed. By Combining the conventional evaluating method for speech enhancement system with modern techniques, a new method was proposed, and an experimental system was eventually worked out.

本文以带噪语音为研究对象，开展了带噪语音增强的基础研究工作，从理论和实践上对语音增强的各种算法进行了深入而系统的研究，尝试了在原有谱相减法的基础上引入隐马尔科夫模型、矢量量化及人工神经网络等研究方法及手段并提出了相应的语音增强算法。

Speech recognition is one of the important contents of the speech signal processing, and how to increase the preciseness in speech recognition is the mainly intention of the speech recognition research.

语音识别是语音信号处理的重要内容之一，如何提高语音识别的正确率则是语音识别研究的主要目的。

The current second-generation and third-generation (3G) mobile communication systems operate with narrow audio bandwidth limited to 200-3400Hz.As wireless systems are evolving from voice-telephony dominated services to multimedia and high-speed data services, the introduction of a wider bandwidth of 50–7000 Hz speech codec which provides substantially improved speech quality and naturalness is quite necessary. The Adaptive Multi-rate Wideband speech codec which was selected by 3GPP/ETSI and ITU-T can provide natural, present and comfortable codec speech and have higher intelligence and robustness in wireless systems. A wide range of applications are envisioned for AMR-WB, including ISDN wideband telephony and audio/video teleconferencing,Voice over IP and Internet applications such as IP video conferencing, voice mail, voice chat, broadcast, and voice streaming.

随着现代无线通信特别是多媒体通信的发展，人们对语音通信的质量要求越来越高。3GPP/ETSI TS026和ITU-T 722.2标准确定的自适应宽带语音编解码器AMR-WB具有的低比特率、互操作性和高语音质量，使之不仅能够应用于无线通信领域，而且可广泛应用于其他各种通信系统和平台，包括：VoIP、因特网、PSTN高质量音频会议、音频流、ISDN宽带电话、ISDN可视电话和电视会议等。

Emphasis is laid on the research progress in the field of new generation speech synthesis technology contributed by USTC iFlytek speech laboratory, which includes integration articulatory and acoustic features for improving the flexibility of acoustic parameter generation; a minimum generation error criterion proposed to replace maximum likelihood for improving synthesized speech quality; use of unit selection and waveform concatenation to replace parametric synthesizer, thus effectively avoiding the limitation of speech quality in HMM based parametric synthesis.
