Functions
void	ComputeKaldiPitch (const PitchExtractionOptions &opts, const VectorBase< BaseFloat > &wave, Matrix< BaseFloat > *output)
	This function extracts (pitch, NCCF) per frame, using the pitch extraction method described in "A Pitch Extraction Algorithm Tuned for Automatic Speech Recognition", Pegah Ghahremani, Bagher BabaAli, Daniel Povey, Korbinian Riedhammer, Jan Trmal and Sanjeev Khudanpur, ICASSP 2014. More...
void	ProcessPitch (const ProcessPitchOptions &opts, const MatrixBase< BaseFloat > &input, Matrix< BaseFloat > *output)
	This function processes the raw (NCCF, pitch) quantities computed by ComputeKaldiPitch, and processes them into features. More...
void	ComputeAndProcessKaldiPitch (const PitchExtractionOptions &pitch_opts, const ProcessPitchOptions &process_opts, const VectorBase< BaseFloat > &wave, Matrix< BaseFloat > *output)
	This function combines ComputeKaldiPitch and ProcessPitch. More...
