The big advances in electronic sign processing (DSP) expertise have contributed to the vast dissemination and good fortune of speech conversation units – be it GSM and UMTS cellular phones, electronic listening to aids, or human-machine interfaces. electronic speech transmission recommendations play an immense position in those functions, the entire extra simply because top of the range speech transmission is still crucial in all present and subsequent new release verbal exchange networks.
Enhancement, coding and blunder concealment thoughts increase the transmitted speech sign in any respect levels of the transmission chain, from the acoustic front-end to the sound copy on the receiver. complex speech processing algorithms support to mitigate a couple of actual and technological obstacles reminiscent of heritage noise, bandwidth regulations, scarcity of radio frequencies, and transmission errors.
Digital Speech Transmission offers a single-source, finished advisor to the basic matters, algorithms, criteria, and traits in speech sign processing and speech verbal exchange expertise. The authors provide a high-quality, available evaluate of
- fundamentals of speech sign processing
- speech coding, together with new speech coders for GSM and UMTS
- error concealment by way of smooth decoding
- artificial bandwidth extension of speech signals
- single and multi-channel noise reduction
- acoustic echo cancellation
