ADINREC(1) 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" op-
tion.
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 adin-
net 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.
