The history and current situation of research in speech recognition are proposed all-sidedly and systematically. We probe into such topics about acoustic features, phonetic features, phonologic features and auditory perception in terms of related theory and disciplines. Furthermore, we summarize and analyze focus in current theoretical and technical aspects of speech recognition and immediately put an insight into challenge to speech recognition presently, even in a long time.

The invention discloses a method for negotiating a voice encoding/decoding format in a communication system, in which a caller mobile station originates to negotiate the voice encoding/decoding format with a callee mobile station, the method comprises that: a mobile switch centre of the communication system receives an originating signal transmitted by the caller mobile station, the originating signal carries the number of the callee mobile station; a voice encoding/decoding format list which is latest used by the callee mobile station is acquired according to the originating signal in a database in which mobile station information is stored; the voice encoding/decoding format used when the caller mobile station is communicated with the callee mobile station is determined, and voice carrier of the caller mobile station and the callee mobile station is established in the voice encoding/decoding format.

本发明公开了一种通信系统中协商语音编解码格式的方法，主叫移动台始发与被叫移动台进行协商语音编解码格式，包括：通信系统中的移动交换中心接收到主叫移动台发送的始呼信号，该始呼信号中携带有被叫移动台的号码；根据始呼信号在存储有移动台信息的数据库中获取到被叫移动台最近使用的语音编解码格式列表；决定主叫移动台与被叫移动台进行通信时使用的语音编解码格式，并且以该语音编解码格式建立主叫移动台和被叫移动台的语音承载。

In 1999 the U.S. began to introduce and promote the ISD voice circuits, are widely used for advertising, product selling machine, recording key chain, telephone response tape recorders, voice alarm systems, toys and other voice recording electronic products, and in 2001 and Hong Kong Ka Ling Electronics, Winbond Electronics to promote a series of voice products and four SCM.

1999年开始引进并推广美国ISD语音电路，产品广泛应用于广告宣传机、产品叫卖机、录音匙扣、电话应答录音机、语音报警系统、录音玩具等多种语音电子产品，并于2001年与香港嘉灵电子合作，大力推广华邦电子的系列语音产品及4位单片机。

It comprises: CN pages call and the page message carries the sonic service information, as the sonic service of CS region; UE responds page, and sends the sonic service information to RNC in the initial access request message; RNC receives request and makes sure it is sonic service of CS region, to decide one sonic speed parameter Rm, and based on the resource demand, to build one wireless chain and ground load between Iub interface signal and service, and the signal and service load of wireless interface; UE and CN processes QoS consultation, and CN sends the consulted Qos parameter to RNC, which comprises a sonic speed parameter Ra of this service; RNC compares parameter Ra and Rm, if Ra is higher then Rm, builds the ground load of Iu interface and sends distribution answer message to CN to continuously page answer process.

一种WCDMA系统被叫侧语音呼叫的快速建立方法，包括步骤：CN寻呼被叫，寻呼消息中携带语音业务信息，指明是CS域的语音业务；UE响应寻呼，在初始接入请求消息中将所述语音业务信息传递到RNC；RNC收到请求并获知是CS域的语音业务后，决策出一个语音速率参数Rm并基于其对资源的要求，建立Iub接口信令和业务的无线链路及地面承载，以及无线接口的信令和业务承载；UE和CN进行QoS协商，CN将协商得到的Qos参数指派给RNC，其中包括本次业务的语音速率参数Ra；RNC比较参数Ra和Rm，如果Ra≥Rm，则建立Iu接口的地面承载，向CN发送指派应答消息，继续呼叫应答过程。

In addition, we proposed a new approach to implement a descrambler. The security problem of speech communication has always been a demanding problem in military and business areas. A common approach to realizing end-to-end security is the use of a scrambler. Most of the scramblers are based on the permutation of speech signals in the time domain and/or frequency domain. On the other hand, descramblers are used to eavesdrop information from scrambled speech signals. We treated the descrambling problem as a puzzle solving problem. Some speech signals were used to demonstrate the performance of the proposed methods.

接著我们将此演算法应用於语音通讯保密的语音解搅拌器上，语音通讯保密已经被广泛应用在军事与商业领域，一般的作法是将语音搅拌器使用在端点对端点的保密上，而大部分的语音搅拌器都是以时域与频域为基础来进行排列搅拌，另一方面语音解搅拌器也必须防止窃听者盗取搅拌后的语音讯号，在此实验上，我们将语音解搅拌的问题视为解拼图的问题，并且利用我们所提出的解拼图方法来实作其应用，最后我们采用一些范例来展示其结果。
