Short-Term Analysis of Speech Signals
Short-term analysis of speech signals includes key components such as frame splitting, short-term energy, short-term average magnitude, short-term zero-crossing rate, short-term autocorrelation function, short-term magnitude difference, cepstrum, complex cepstrum, LPC coefficients, and LPC spectral estimation. These fundamental programs assigned by my supervisor after securing postgraduate admission ensure absolute quality through robust implementation.
Short-Time Analysis of Speech Signals
Speech signals are time-varying in nature, with individual parameter variations occurring more gradually than the signal itself. Consequently, measuring these parameters requires a significantly lower sampling frequency compared to the signal's original sampling rate. Through window function weighting, the signal is segmented in the time domain into local signal sequences for measurement. Proper short-time analysis requires defining two key dimensions: window length (duration of the weighted signal segment) and measurement interval (frame rate, representing the spacing between consecutive windows). Core short-time analysis operations include short-time energy (reflecting amplitude variations), short-time autocorrelation function (detecting periodicity), and short-time zero-crossing rate.
