Extraction of Pitch and Formants and its Analysis to identify 3 different emotional states of a person
Pitch and formant frequencies are important features in speech which are used to identify the emotional state of a person. The Pitch and Formants are first extracted from the speech signal and then their analysis is carried out to recognize 3 different emotional states of the person. The emotions considered are Neutral, Happy and Sad. The TU-Berlin database has been used for the analysis. The Cepstral analysis method is used for pitch extraction and LPC analysis method is used to extract the formant frequencies.
Keywords: feature extraction, pitch, formant frequencies, emotion, cepstrum, LPC.
