Getting the file recorded from PocketSphinx

[Senjam Shantirani]

Is there a way to capture the wave file recorded from pocketsphinx.
Please help.

From the command line use option -rawlogdir <dir> to store dumps in a folder.

From the code use ps_set_rawdata_size and ps_get_rawdata to retrieve recorded audio.

How do we improve the PocketSphinx accuracy?
Any parameter to tune for better accuracy?

I get the raw data using the -rawlogdir

and when I tried to convert to wav it has huge noise.

I used both the commands below, but I cannot hear what was recorded instead huge noise.

sox -r 44100 -e unsigned -b 8 -c1 000000002.raw test_file.wav
sox -r 44100 -e unsigned -b 8 -c1 000000002.raw test_file.wav

Can you suggest me a conversion process which can give me a good .wav file.

The correct command is

sox -r 16000 -e signed -b 16 000000002.raw test_file.wav
