No results in Streaming speech recognition #316
Description
Hey, i literally tried everything. @jmdobry could you look?
The response is always empty, when using the nodejs-docs-samples/speech/recognize.js with parameter listen
The examples with use of reading from the file works fine.
- I had to change line 16 to:
recordProgram: 'sox'
in file
\node-record-lpcm16\index.js
because the program uses "rec" by default, not "sox", and with "rec" there is an error, because there is not such file
- for troubleshooting, i edited line 226 in file recognize.js to:
.on('data', (data) => {process.stdout.write(data.results); console.log(data);}
and the result is:
Listening, press Ctrl+C to stop.
{ error: null,
results: '',
resultIndex: 0,
endpointerType: 'END_OF_AUDIO' }
previously did "install" command as described in the readme
win 8.1 pro
sox 14.4.2 from official site https://sourceforge.net/projects/sox/files/sox/14.4.2/ && path added to environmental "path" ( "sox" typed in cmd.exe works fine)
Node.js v 7.5.0

Moreover, depending on the signal level, the process ends after 0.5 - 5 seconds, but no matter how good audio is (i am using kinda "loopback", so the audio from the american native speakers recorded in good quality gets directly to mic input of the computer)
The audio was thoroughly tested, and the same audio when streamed from file, as a file, not realtime streaming, is recognised with 95% efficiency (about 5% words misunderstood)

tried version 0.1.4 of the rec library (as suggested in one of threads by @jmdobry is guess) (also with change: line 26 to
var cmd = 'sox';fromvar cmd = 'rec';same result - not working
