Origin of Speech Coding “Watson, if I can get a mechanism which will make a current of electricity vary its intensity as the air varies in density when sound is passing through it, I can telegraph any sound, even the sound of speech.” A. G. Bell’1875 analog communication H X =−∑ i=1 N

II. Basic Issues in Speech Coding Speech and audio coding can be classified according to the bandwidth occupied by the input and the reproduced source. Narrowband or telephone bandwidth speech occupies the band from 200 to 3400 Hz, while wideband speech is contained in the range of 50 Hz to 7 kHz. High quality audio is generally taken

Speech coding is a lossy type of coding and hence the output signal does not exactly sound like the input. Speech coding techniques discussed here are Linear predictive coding, waveform coding, Code excited linear predictive coding, etc. Linear Predictive Coding and Code Excited Linear Predictive Coding techniques are studied with the help of MATLAB to …

The audio coding algorithms described in this chapter take, in some sense, the opposite tack from the speech coding algorithms described previously. Instead of focusing on the source of information, as is the case with the speech coding algorithm, the focus in the audio coding algorithm is on the sink, or user, of the information.

speech coding include cellular communication, voice over internet protocol (VOIP), videoconferencing, electronic toys, archiving, and digital simultaneous voice and data (DSVD), as well as numerous PC-based games and multimedia applications. Speech coding is the art of creating a minimally redundant representation of the speech signal that can

• Speech coding is necessary for cellular phones, which has limited data rate for each user (<=16 kbps is desired!). • For the same mobile user, the lower the bit rate for a voice call, the more other services (data/image/video) can be accommodated. • Speech coding is also necessary for voice-over-IP, audio-visual

Audio Coding ! Quantization and transformation of data are collectively known as coding of the data. ! For audio, the -law technique for compounding audio signals is usually combined with an algorithm that exploits the temporal redundancy present in audio signals. !

Speech/audio coding has traditionally involved substantial domain-specific knowledge such as speech generation models. If you haven’t heard of this concept, don’t worry, because you might be using this technology in your everyday life, e.g., when you are on the phone, listening to the music using your mobile device, watching television, etc.
