Pocketsphinx in BeagleBoard + Angstrom Linux

[Diego Garcia]

Hi everybody!,

I'm having troubles with using pocketsphinx on my beagleboard. I work with
Angstrom linux distro, but the ipks available from the angstrom repository
seem to be quite old, so i've tried to compile pocketsphinx and sphinxbase
from the last version.

I've compiled sphinxbase and I noticed that configure file doesn't find
asoundlib.h, so I guess it's not loading alsa support. I've not found which
package I should install to get this libraries loaded, so I've continued with
compiling pocketsphinx.

Finally, when I run pocketsphinx_continuous I get the following message:

ad_oss.c(103): Failed to open audio device(/dev/dsp): No such file or
directory
FATAL_ERROR: "continuous.c", line 259: ad_open_dev failed

So I've tried to use AOSS to wrap with alsa default device. Pocketsphinx runs
and it reaches READY, but after "listening" I get the following message:
"READY....
Listening...
Audio ioctl(SYNC) failed: Resource temporarily unavailable"

I don't know how to continue, I've asked in beagleboard chats, but nobody
knows how to proceed. Can you help me?

Best regards,

Diego

It's better to compile sphinxbase with alsa support. It compiled with oss
support because you missed alsa developement package. asoundlib.h is part of
libasound2-dev in debian-based distributions.
