Analysis and Detection of Emotional states of a person by extracting Pitch and Formants with respect to Assamese Language
نویسنده
چکیده
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 TTS-GU 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.
