livery Signal Processing ?????? schooling of Electronic Information, Wuhan University Chapter 3 manner of speaking Analysis The previous chapter on tongue science examined the return and companionship of natural quarrel and set forth important aspects of linguistic process for human race communication. Applications of speech processing (e,g., coding, synthesis, recognition) exploit these properties. To store or recognize speech, reducing plaeonasm in the speech waveform permits efficient representation of the essential speech aspects in the form of parameters. The applicable parameters for speech recognition must be consistent across speakers, and should cave in similar values for the alike sounds uttered by miscellaneous speakers, go exhibiting reliable variation for gelid sounds. Synthetic speech must replicate perceptually crucial properties of the speech, nevertheless may ignore other aspects. This chapter short examines methods of speech abridgment, in some(prenominal) the eon and frequency domains. There argon tradeoffs when analyzing a time-varying signal such as speech; in examining a window of speech, the weft of epoch and shape for the window reflects a compromise in time and frequency annunciation.

Accurate time solvent helps when segmenting speech signals and ascertain reposition periods, whereas good frequency resolution helps to identify contrary sounds. Time analysis is rapid but is express mail to simple speech measures, e.g., energy and periodicity, while spectral analysis takes more than than effort but characterizes sounds more precisely. 3.1 inherent of digital Speech signal 3.2 Time-domain analysis 3.3 Frequency-domain analysis 3.4 Cepstral analysis 3.5 linear prediction analysis 3.1 Fundamental of Digital Speech signal 3.1.1 Overview An underlying manikin of speech production involving an innervation inception and a vocal piece of land filter is covert in many analysis methods. rough techniques try to fragment these dickens aspects of a speech signal.
