Hello!

I'm trying to test Julius and Julius-voxforge, and when I try to start the recognition, julius runs but I don't receive any recognition, when it starts I got the next messages, warnings and errors:

### read waveform input
Stat: capture audio at 16000Hz
Stat: adin_alsa: latency set to 32 msec (chunk = 512 bytes)
Error: adin_alsa: unable to get pcm info from card control
Warning: adin_alsa: skip output of detailed audio device info
STAT: AD-in thread created

The program runs, but while I'm speaking, and I got these warnings:

Warning: strip: sample 287-302 has zero value, stripped
Warning: strip: sample 32-47 has zero value, stripped
Warning: strip: sample 251-266 has zero value, stripped
Warning: strip: sample 497-512 has zero value, stripped
Warning: strip: sample 563-579 has zero value, stripped
Warning: strip: sample 53-68 has zero value, stripped
Warning: strip: sample 196-212 has zero value, stripped
Warning: strip: sample 341-356 has zero value, stripped
Warning: strip: sample 606-621 has zero value, stripped

and after a time, I got this warning:

WARNING: adin_thread_process: too long input (> 320000 samples), segmented now
Warning: input buffer overflow: some input may be dropped, so disgard the input

and the program continues in an infinite loop.


Also, I run the program with the command -record and if I open the file with VLC, i can hear the sound fine.

 

Does anybody have idea what can I do to run it?

Can anybody help me, please?

Thanks!

Diego

For the message "Warning: strip: sample 287-302 has zero value, stripped" see the command line/config varaible  -nostrip  "disable stripping off zero samples"

For the message "WARNING: adin_thread_process: too long input" you are giving Julius more than 20s of audio and it didn't find a sp to segment on (assuming you set this).
Julius is very difficult to set up correctly.   I suggest that you first record short, easy to recognise, sentences to files and get it going well on that before moving on.   You will need to understand all of the beam pruning parameters and most of the other config variables.
Good luck,
Tony
