AbstractFundamentals of speech signal processing and introduction to text-to-speech synthesis and speech recognition.
ObjectiveKnowledge of the basics in speech processing. Acquisition of practical experience in this field. Comprehension of the fundamental problems of text-to-speech synthesis and speech recognition and selected solutions.
ContentAnalysis, representation and properties of speech signals: Time and frequency domain representations, quasi-stationarity, formants, pitch, short-time analysis, spectrum, autocorrelation, linear prediction, homomorphic analysis.
Fundamental problems of speech synthesis: Relations between text and speech; methods of speech production; prosody control.
Fundamental problems of speech recognition: Variability of speech signals, speech features for speech recognition, pattern matching (distance measures, dynamic programming), and introduction to statistical speech recognition with hidden Markov models.
