	This code computes Goodness of Pronunciation (GOP) and extracts phone-level pronunciation feature for mispronunciations detection tasks, the reference:

Functions
int64	FirstSampleOfFrame (int32 frame, const FrameExtractionOptions &opts)

int32	NumFrames (int64 num_samples, const FrameExtractionOptions &opts, bool flush=true)
	This function returns the number of frames that we can extract from a wave file with the given number of samples in it (assumed to have the same sampling rate as specified in 'opts'). More...

void	Dither (VectorBase< BaseFloat > *waveform, BaseFloat dither_value)

void	Preemphasize (VectorBase< BaseFloat > *waveform, BaseFloat preemph_coeff)

void	ProcessWindow (const FrameExtractionOptions &opts, const FeatureWindowFunction &window_function, VectorBase< BaseFloat > window, BaseFloat log_energy_pre_window=NULL)
	This function does all the windowing steps after actually extracting the windowed signal: depending on the configuration, it does dithering, dc offset removal, preemphasis, and multiplication by the windowing function. More...

void	ExtractWindow (int64 sample_offset, const VectorBase< BaseFloat > &wave, int32 f, const FrameExtractionOptions &opts, const FeatureWindowFunction &window_function, Vector< BaseFloat > window, BaseFloat log_energy_pre_window)
