Constructor & Destructor Documentation

alize::FeatureFileReaderHTK::FeatureFileReaderHTK	(	const FileName &	f,
		const Config &	c,
		LabelServer *	ls = NULL,
		BigEndian	= BIGENDIAN_AUTO,
		BufferUsage	= BUFFER_AUTO,
		unsigned long	bufferSize = 0,
		HistoricUsage	= ALL_FEATURES,
		unsigned long	historicSize = 0
	)

Creates a reader for a HTK feature file.

Parameters:

f	a file to read. No path is required. It uses the parameter "featureFilesPath" of the configuration.
c	the configuration to use
ls	address of a label server. can be NULL.
be	big endian ? Can be BIGENDIAN_AUTO, BIGENDIAN_TRUE or BIGENDIAN_FALSE
