Formant and Pitch Detection Using Time-Frequency Distribution

  • Wanda W. Zhao

The Wigner-Ville distribution of a multi-component signalhas a unique structure. Based on this structure, a formant and pitchestimation method for speech signals is introduced. Formants andpitch estimated with this method are more accurate, have betterresolution, and are easier to recognize than those estimated by othermethods. A one pitch-period segment is adequate for formantestimation while a minimal two pitch-period segment is needed forboth pitch and formant detection with one step. Experimental resultsare provided to demonstrate the performance of this method, andcomparisons with other methods are provided.
