6.2.4 SCRIBE Label Files

  The SCRIBE label file format is a subset of the European SAM label file format. SAM label files are text files and each line begins with a label identifying the type of information stored on that line. The HTK SCRIBE format recognises just three label types

 
		 LBA 		- acoustic label

		 LBB 		- broad class label

		 UTS 		- utterance

For each of these, the rest of the line is divided into comma separated fields. The LBA and LBB types have 4 fields: start sample, centre sample, end sample and label. HTK expects the centre sample to be blank. The UTS type has 3 fields: start sample, end sample and label. UTS labels may be multi-word since they can refer to a complete utterance. In order to make such labels usable within HTK tools, between word blanks are converted to underscore characters. The EX  command in the HTK label editor HLED can then be used to split such a compound label into individual word labels if required.
