NAME

pocketsphinx_batch - Run speech recognition in batch mode

SYNOPSIS

pocketsphinx_batch -hmm hmmdir -dict dictfile [ options ]...

DESCRIPTION

Run speech recognition over a list of utterances in batchmode. A list of arguments follows: -adcdev name for audio input (platform-specific) -adchdr Size of audio file header in bytes (headers are ignored) -adcin Input is raw audio data -agc Automatic gain control for c0 ('max', 'emax', 'noise', or 'none') -agcthresh Initial threshold for automatic gain control -allphone Do phoneme recognition -alpha Preemphasis parameter -backtrace Print back trace of recognition results -beam Beam width applied to every frame in Viterbi search (smaller values mean wider beam) -bestpath Run bestpath (Dijkstra) search over word lattice (3rd pass) -bestpathlw Language model probability weight for bestpath search -cachesen Cache senone scores from first pass search -cep2spec Input is cepstral files, output is log spectral files -cepdir files directory (prefixed to filespecs in control file) -cepext Input files extension (prefixed to filespecs in control file) -ceplen Number of components in the input feature vector -cmn Cepstral mean normalization scheme ('current', 'prior', or 'none') -cmninit Initial values (comma-separated) for cepstral mean when 'prior' is used -compallsen Compute all senone scores in every frame (can be faster when there are many senones) -ctl file listing utterances to be processed -ctlcount No. of utterances to be processed (after skipping -ctloffset entries) -ctlincr Do every Nth line in the control file -ctloffset No. of utterances at the beginning of -ctl file to be skipped -dict pronunciation dictionary (lexicon) input file -dither Add 1/2-bit noise -doublebw Use double bandwidth filters (same center freq) -dsratio Frame GMM computation downsampling ratio -fbtype FB Type of mel_scale or log_linear -fdict word pronunciation dictionary input file -feat Feature stream type, depends on the acoustic model -fillpen Filler word transition penalty -frate Frame rate -fsg state grammar -fsgbfs Force backtrace from FSG final state -fsgctlfn finite state grammar control file -fsgusealtpron Use alternative pronunciations for FSG -fsgusefiller (FSG Mode (Mode 2) only) Insert filler words at each state. -fwd3g Use trigrams in first pass search -fwdflat Run forward flat-lexicon search over word lattice (2nd pass) -fwdflatbeam Beam width applied to every frame in second-pass flat search -fwdflatefwid Minimum number of end frames for a word to be searched in fwdflat search -fwdflatlw Language model probability weight for flat lexicon (2nd pass) decoding -fwdflatsfwin Window of frames in lattice to search for successor words in fwdflat search -fwdflatwbeam Beam width applied to word exits in second-pass flat search -fwdtree Run forward lexicon-tree search (1st pass) -hmm containing acoustic model files. -hyp output file name -hypseg output with segmentation file name -input_endian Endianness of input data, big or little, ignored if NIST or MS Wav -kdmaxbbi Maximum number of Gaussians per leaf node in kd-Trees -kdmaxdepth Maximum depth of kd-Trees to use -kdtree file for Gaussian selection -latsize Lattice size -lifter Length of sin-curve for liftering, or 0 for no liftering. -live Get input from audio hardware -lm trigram language model input file -lmctl a set of language model The -hmm and -dict arguments are always required. Either -lm or -fsg is required, depending on whether you are using a statistical language model or a finite-state grammar. To do batchmode recognition, you will need to specify a control file, 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 directory, 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
