摘要： A method, system and program for encoding and decoding speech according to a source-filter model whereby speech is modelled to comprise a source signal filtered by a time-varying filter. The method comprises: receiving a speech signal comprising successive frames, for each of a plurality of frames of the speech signal, deriving a first line spectral frequency vector for a first portion of the frame, and a second line spectral frequency vector for a second portion of the frame, and determining a transmit line spectral frequency vector and an interpolation factor based on the first and second line spectral frequency vectors, and on the transmit line spectral frequency vector for a preceding one of the frames.

摘要： A first user terminal, host terminal, method and program. The first terminal comprises: a transceiver for communicating with a plurality of other user terminals over a communication network; and communications processing apparatus, coupled to the transceiver, and arranged to participate in a call with a selected number of the other user terminals via the transceiver and communication network, the call including transmission of a voice signal from the first user terminal. The communications processing apparatus is operable in a mode whereby it temporarily discontinues transmission of the voice signal in response to detecting less than a predetermined level of activity on said voice signal, and the communications processing apparatus is further configured to selectively enable that mode in dependence on the selected number of other user terminals in the call.
摘要翻译：第一个用户终端，主机终端，方法和程序。第一终端包括：收发器，用于通过通信网络与多个其他用户终端进行通信; 以及通信处理装置，其耦合到所述收发器，并且被布置成经由所述收发器和通信网络参与与选定数量的其他用户终端的呼叫，所述呼叫包括来自所述第一用户终端的语音信号的传输。通信处理装置可以以这样一种模式操作，由此响应于检测到小于所述语音信号的预定活动水平而暂时停止语音信号的发送，并且通信处理装置还被配置为根据呼叫中所选择的其他用户终端数。

摘要： A method of estimating noise in data containing voice information and noise comprising the steps of receiving the data as a sequence of input values; transforming the data by applying a first non linear mapping to the input values wherein the derivative function of the mapping decreases in magnitude as the input values increase in magnitude smoothing the transformed data; and transforming the smoothed transformed data by applying a second non linear mapping that is opposite to the first non linear mapping, to determine an estimate of the noise in the inputted data.
摘要翻译：一种在包含语音信息和噪声的数据中估计噪声的方法，包括以下步骤：接收数据作为输入值序列; 通过对输入值应用第一非线性映射来变换数据，其中映射的导数函数随着输入值在幅度上增加而平滑化变换后的数据; 以及通过应用与第一非线性映射相反的第二非线性映射来变换平滑变换的数据，以确定输入数据中噪声的估计。
