adinrec(1)
NAME
- adinrec
- - record audio device and save one utterance to a file
SYNOPSIS
adinrec [options...] {filename}
DESCRIPTION
adinrec opens an audio stream, detects an utterance input and store it
to a specified file. The utterance detection is done by level and
zero-cross thresholds. Default input device is microphone, but other
audio input source, including Julius A/D-in plugin, can be used by
using "-input" option.
The audio format is 16 bit, 1 channel, in Microsoft WAV format. If the
given filename already exists, it will be overridden.
If filename is "-" , the captured data will be streamed into standard
out, with no header (raw format).
OPTIONS
- adinrec uses JuliusLib and adopts Julius options. Below is a list of
valid options.
- adinrec specific options
- -freq Hz
Set sampling rate in Hz. (default: 16,000)
- -raw
Output in raw file format.
- JuliusLib options
- -input {mic|rawfile|adinnet|stdin|netaudio|esd|alsa|oss}
Choose speech input source. Specify 'file' or 'rawfile' for waveform file. On file input, users will be prompted to enter the file name
from stdin.'mic' is to get audio input from a default live microphone device,
and 'adinnet' means receiving waveform data via tcpip network from
an adinnet client. 'netaudio' is from DatLink/NetAudio input, and
'stdin' means data input from standard input.At Linux, you can choose API at run time by specifying alsa, oss and esd. - -lv thres
Level threshold for speech input detection. Values should be in
range from 0 to 32767. (default: 2000) - -zc thres
Zero crossing threshold per second. Only input that goes over the
level threshold (-lv) will be counted. (default: 60) - -headmargin msec
Silence margin at the start of speech segment in milliseconds.
(default: 300) - -tailmargin msec
Silence margin at the end of speech segment in milliseconds.
(default: 400) - -zmean
This option enables DC offset removal.
- -smpFreq Hz
Set sampling rate in Hz. (default: 16,000)
- -48
Record input with 48kHz sampling, and down-sample it to 16kHz
on-the-fly. This option is valid for 16kHz model only. The
down-sampling routine was ported from sptk. (Rev. 4.0) - -NA devicename
Host name for DatLink server input (-input netaudio).
- -adport port_number
With -input adinnet, specify adinnet port number to listen. (default: 5530)
- -nostrip
Julius by default removes successive zero samples in input speech
data. This option stop it. - -C jconffile
Load a jconf file at here. The content of the jconffile will be
expanded at this point. - -plugindir dirlist
Specify which directories to load plugin. If several direcotries
exist, specify them by colon-separated list.
ENVIRONMENT VARIABLES
- ALSADEV
- Device name string for ALSA. (default: "default")
- AUDIODEV
- Device name string for OSS. (default: "/dev/dsp")
- LATENCY_MSEC
- Input latency of microphone input in milliseconds. Smaller value
will shorten latency but sometimes make process unstable. Default
value will depend on the running OS.
