Classes
struct	OnlineEndpointRule
	This header contains a simple facility for endpointing, that should be used in conjunction with the "online2" online decoding code; see ../online2bin/online2-wav-gmm-latgen-faster-endpoint.cc. More...
struct	OnlineEndpointConfig

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

Functions
bool	EndpointDetected (const OnlineEndpointConfig &config, int32 num_frames_decoded, int32 trailing_silence_frames, BaseFloat frame_shift_in_seconds, BaseFloat final_relative_cost)
	This function returns true if this set of endpointing rules thinks we should terminate decoding. More...
template<typename FST , typename DEC >
int32	TrailingSilenceLength (const TransitionModel &tmodel, const std::string &silence_phones, const DEC &decoder)
	returns the number of frames of trailing silence in the best-path traceback (not using final-probs). More...
template<typename FST >
bool	EndpointDetected (const OnlineEndpointConfig &config, const TransitionModel &tmodel, BaseFloat frame_shift_in_seconds, const LatticeFasterOnlineDecoderTpl< FST > &decoder)
	This is a higher-level convenience function that works out the arguments to the EndpointDetected function above, from the decoder. More...
template<typename FST >
bool	EndpointDetected (const OnlineEndpointConfig &config, const TransitionModel &tmodel, BaseFloat frame_shift_in_seconds, const LatticeIncrementalOnlineDecoderTpl< FST > &decoder)
	This is a higher-level convenience function that works out the arguments to the EndpointDetected function above, from the decoder. More...
