SPHINX_CONT_SEG(1)

✨ SPHINX_CONT_SEG ✨

okay bestie, gather round, because sphinx_cont_seg is a section 1 general commands manual page and it is literally here to chop your waveform into the non-silence bits. no cap. 🎀

🌸 NAME 🌸

sphinx_cont_seg — segment a waveform file into non-silence regions 🦋

💫 SYNOPSIS 💫

sphinx_cont_seg [ options ]...

👑 DESCRIPTION 👑

so the way this works: this program reads an input file and segments it into individual non-silence regions. it can process either a file or read data straight from the microphone. main character energy fr fr. 💅

use following arguments:

✨ OPTIONS ✨

• -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
