摘要： When one vocoding system is coupled to another vocoding system, a tandem arrangement results. The tandem configuration results in voice quality degradation as speech is encoded and decoded, then encoded and decoded again. One reason for the degradation is that postfiltering performed at the output of the speech decoding process introduces distortions in the spectral content of the reconstructed speech as compared to the original speech. The present invention prevents the degradation due to the use of postfilters by modifying the postfiltering within the vocoders where a tandem configuration exists. A detection code is embedded within the data signal to indicate the existence of a tandem configuration. If the detection code is received at a vocoder, modified vocoding is established within the vocoders to prevent the degradation due to the postfiltering.
摘要翻译：当一个声码系统耦合到另一个声码系统时，会产生串联排列。串音配置导致语音质量下降，因为语音被编码和解码，然后被再次编码和解码。降级的一个原因是在语音解码过程的输出处执行的后置滤波与原始语音相比引入了重构语音的频谱内容中的失真。本发明通过修改存在串列配置的声码器中的后置滤波来防止由于使用后置滤波器导致的劣化。检测码嵌入在数据信号中以指示串联配置的存在。如果在声码器处接收到检测码，则在声码器内建立修改后的声码，以防止由于后置滤波引起的劣化。

摘要： An apparatus and method for performing speech signal compression, by variable rate coding of frames of digitized speech samples. The level of speech activity for each frame of digitized speech samples is determined and an output data packet rate is selected from a set of rates based upon the determined level of frame speech activity. A lowest rate of the set of rates corresponds to a detected minimum level of speech activity, such as background noise or pauses in speech, while a highest rate corresponds to a detected maximum level of speech activity, such as active vocalization. Each frame is then coded according to a predetermined coding format for the selected rate wherein each rate has a corresponding number of bits representative of the coded frame. A data packet is provided for each coded frame with each output data packet of a bit rate corresponding to the selected rate. At the decoder, if a frame is lost due to a channel error, the error is masked by maintaining a fraction of the previous frame's energy and smoothly transitioning to background noise.

摘要： It is a first objective of the present invention to provide a method by which to reduce the probability of coding low energy unvoiced speech as background noise. The present invention determines an encoding rate by examining subbands of the input signal, by this method unvoiced speech can be distinguished from background noise. A second objective of the present invention is to provide a means by which to set the threshold levels that takes into account signal energy as well as background noise energy. In the present invention, the background noise is not used to determine threshold values, rather the signal to noise ratio of an input signal is use to determine the threshold values. A third objective of the present invention is to provide a method for coding music passing through a variable rate vocoder. The present invention examines the periodicity of the input signal to distinguish music from background noise.

摘要： A method and system by which parameter data representative of vocoded speech are organized into a data packet for transmission so as to reduce the impact of transmission channel induced errors on the data packet. A data packet is constructed with certain most perceptually significant bits of parameter data at the beginning of the data packet. Following in the data packet are lesser perceptually significant bits of the same parameter data. Other parameter data then follows in the data packet. Interleaved in the data packet following the most perceptually significant bits at the beginning of the data packet are most perceptually significant bits of other parameter data. A parity check code is computed from the most perceptually significant bits in the data packet and also interleaved in the data packet following the most perceptually significant bits at the beginning of the data packet.
