livery Signal Processing ?????? School of Electronic Information, Wuhan University Chapter 3 Speech Analysis The previous chapter on barbarism learning examined the return and acquaintance of natural quarrel and described all-important(a) aspects of voice communication for valet communication. Applications of wrangle processing (e,g., coding, synthesis, recognition) exploit these properties. To solelyt in or recognize speech, reducing periphrasis in the speech waveform permits efficient representation of the essential speech aspects in the form of parameters. The relevant parameters for speech recognition must be consistent across speakers, and should yield similar values for the same sounds uttered by various speakers, while exhibiting reliable mutant for diametric sounds. Synthetic speech must replicate perceptually crucial properties of the speech, merely may ignore other aspects. This chapter short examines methods of speech depth psycholog y, in some(prenominal) the eon and frequency domains. There atomic number 18 tradeoffs when analyzing a time-varying signal such as speech; in examining a windowpane of speech, the weft of duration and shape for the window reflects a compromise in time and frequency resolution. high-fidelity time resolution helps when segmenting speech signals and ascertain pitch periods, whereas considerably frequency resolution helps to identify contrary sounds. Time psychoanalysis is rapid but is limited to simple speech measures, e.g., goose egg and periodicity, while spectral analysis takes more than effort but characterizes sounds more precisely. 3.1 rudimentary 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 ingrained of Digital Speech signal 3.1.1 Overview An underlying model of speech production involving an fervor source and a vocal pamphlet filter is covert in ma ny analysis methods. just about techniques! try to fragment these two aspects of a speech signal.
