using -ctl This is a simple text file containing one entry per line. Each entry is the name of an input file relative to the -cepdir direc- tory, and without the filename extension (which is given in the -cepext argument). If you are using acoustic feature files as input (see sphinx_fe(1) for information on how to generate these), you can also specify a subpart of a file, using the following format: FILENAME START-FRAME END-FRAME UTTERANCE-ID AUTHOR Written by numerous people at CMU from 1994 onwards.
