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
