Speech Coders for Mobile Communications
نویسندگان
چکیده
Speech Coding at low and very low bit rate has become the paramount importance in accommodating the tremendous increase in the number of users in the presence of constraints of bandwidth and power in such areas as cellular radio, GSM or satellite links. The paper will cover important areas in Speech Coding. First part is concerned with an overview of the speech production model. The second part Speech coding techniques include the main three areas of coding; waveform coding, Vocoder coding and Hybrid coding. The paper also goes briefly over the main thrust of recent work on speech coding is to reduce the transmission bit rate.

متن کاملStatistical Methods for the Enhancement of Noisy Speech
With the advent and wide dissemination of mobile communications, speech processing systems must be made robust with respect to environmental noise. In fact, the performance of speech coders or speech recognition systems is degraded when the input signal contains a significant level of noise. As a result, speech quality, speech intelligibility, or recognition rate requirements cannot be met. Imp...
