struct  ExampleGenerationConfig
struct  ChunkTimeInfo
 struct ChunkTimeInfo is used by class UtteranceSplitter to output information about how we split an utterance into chunks. More...
class  UtteranceSplitter
class  ExampleMergingConfig
struct  ExampleMergingConfig::IntSet
class  ExampleMergingStats
 This class is responsible for storing, and displaying in log messages, statistics about how examples of different sizes (c.f. More...
struct  ExampleMergingStats::StatsForExampleSize
class  ExampleMerger
 This class is responsible for arranging examples in groups that have the same strucure (i.e. More...


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


void MergeExamples (const std::vector< NnetExample > &src, bool compress, NnetExample *dest)
 Merge a set of input examples into a single example (typically the size of "src" will be the minibatch size). More...
void ShiftExampleTimes (int32 t_offset, const std::vector< std::string > &exclude_names, NnetExample *eg)
 Shifts the time-index t of everything in the "eg" by adding "t_offset" to all "t" values. More...
void GetComputationRequest (const Nnet &nnet, const NnetExample &eg, bool need_model_derivative, bool store_component_stats, ComputationRequest *computation_request)
 This function takes a NnetExample (which should already have been frame-selected, if desired, and merged into a minibatch) and produces a ComputationRequest. More...
void WriteVectorAsChar (std::ostream &os, bool binary, const VectorBase< BaseFloat > &vec)
void ReadVectorAsChar (std::istream &is, bool binary, Vector< BaseFloat > *vec)
int32 GetNnetExampleSize (const NnetExample &a)
 This function returns the 'size' of a nnet-example as defined for purposes of merging egs, which is defined as the largest number of Indexes in any of the inputs or outputs of the example. More...
