SPEECH PROCESSING AND APPLICATION
Speech production and Perception: Anatomy and physiology of speech production;
Articulatory, Linguistic, acoustic and perceptual descriptions. Speech coding and analysis:
Speech digitization techniques,PCM,DPCM,ADPCM, Sub band coding,LPC,Formant synthesis,
Speech digitization direction, Physical features of Speech signals, feature extraction, signal
preprocessing, windowing, Spectral analysis, Filter bank processing, log energy computation,
Mel frequency Cepstrum computation, Cepstrum analysis. Speech Recognition: Issues in Speech
recognition, Spectrum distance measures for speech recognition, auditory measures for speech
recognition, auditory nerve representation as a basic for speech processing; Dynamic
programming based speech recognition algorithms, HMM models for speech recognition, Neural
network approach.Speaker Recognition: Issues in speaker recognition and speech synthesis of
different speakers. Text to speech conversion, Letter to sound rules, Dictionaries, prosody,
Intonation, Calculating acoustic parameters, synthesized speech output performance and
characteristics of text to speech, application of text to speech technology products. Voice
processing hardware and software architectures. Speech Enhancement: Noise suppression with
pattern matching, adaptive echo cancellation for speech signals.
