NAME

       sphinx_cont_seg - Segment a waveform file into non-silence regions

SYNOPSIS

       sphinx_cont_seg [ options ]...

DESCRIPTION

       This  program  reads an input file and segments it into individual non-silence regions. It
       can process either file or read data from microphone. Use following arguments:

       -adcdev
              of audio device to use for input.

       -alpha Preemphasis parameter

       -argfile
              file giving extra arguments.

       -dither
              Add 1/2-bit noise

       -doublebw
              Use double bandwidth filters (same center freq)

       -frate Frame rate

       -infile
              of audio file to use for input.

       -input_endian
              Endianness of input data, big or little, ignored if NIST or MS Wav

       -lifter
              Length of sin-curve for liftering, or 0 for no liftering.

       -logspec
              Write out logspectral files instead of cepstra

       -lowerf
              Lower edge of filters

       -ncep  Number of cep coefficients

       -nfft  Size of FFT

       -nfilt Number of filter banks

       -remove_dc
              Remove DC offset from each frame

       -remove_noise
              Remove noise with spectral subtraction in mel-energies

       -remove_silence
              Enables VAD, removes silence frames from processing

       -round_filters
              Round mel filter frequencies to DFT points

       -samprate
              Sampling rate

       -seed  Seed for random number generator; if less than zero, pick our own

       -singlefile
              a single cleaned file.

       -smoothspec
              Write out cepstral-smoothed logspectral files

       -transform
              Which type of transform to use to calculate cepstra (legacy, dct, or htk)

       -unit_area
              Normalize mel filters to unit area

       -upperf
              Upper edge of filters

       -vad_postspeech
              Num of silence frames to keep after from speech to silence.

       -vad_prespeech
              Num of speech frames to keep before silence to speech.

       -vad_startspeech
              Num of speech frames to trigger vad from silence to speech.

       -vad_threshold
              Threshold for decision between noise and silence frames. Log-ratio  between  signal
              level and noise level.

       -verbose
              Show input filenames

       -warp_params
              defining the warping function

       -warp_type
              Warping function type (or shape)

       -wlen  Hamming window length
