Hi everybody,

 

I know that this topic should be in the CMU sphinx forum, but I enjoye this one so.

Well, my problem is. On the pocketSphinxs web page

http://www.speech.cs.cmu.edu/pocketsphinx/

it is well explain how to compile and to install the sources.

But main problem, I don't find any examples or demos of the Sphinxpocket .!! and I know that they are somewhere !!

So does someone point me on the good website.

DOes it exist for LInux only executable with demo and a file for explaining howto use the sooftware ??

 

THx a lotSmile

regards

You have to build it first, download sphinxbase, unpack it, run

./configure && make && sudo make install

 

then download pocketsphinx, unpack it, run

 ./configure && make && sudo make install 

 then run pocketsphinx_test or pocketsphinx_tidigits. If you'll have troubles with build, google for some documentation on building Linux programs first. Something like 

  http://www.tuxfiles.org/linuxhelp/softinstall.html

 will help you. Also check sphinx wiki, it has tutorials but they are partially out-of-date.

 http://sphinx.subwiki.com

hello;

thanx you for the feedback.
It is no problem for me to install soft on Linux. PocketSphinkx and sphinxbase are already installed.

But, In fact I don't know how to use the soft. What command do Ihave to type in the shell to execute the programm; and How to use the example given in the directorie Model ??

I would like to test my voice and I don't know in the example given such as turtle in model/lm ; what sentences to say according to which grammar file ??

Do you understand my problem?

I can't appreciate the software without executing it !!

Run pocketsphinx_tidigits, say any sequence of numbers. Open this script with text editor and learn how to use pocketsphinx_continuous.

Also run pocketsphinx_swb, say any simple phrase. Swb is a language model for limited but rather big vocabulary (3000 words). You can also open this script if you like

Run any pocketsphinx binary like batch and continuous without arguments and get help on options. If you have any troubles just ask. Also you can ask on #cmusphinx irc channel on freenode.net.

 Hi All,

I want to install pocketPhinix to sharp zaurus PDA but pocketPhinix can’t compile on PDA since its low resources. Then source should be cross compile to PDA. Can anyone help me to build cross compiler to host that cross compile PocketPhinix into target of zaurus. hope you comment it on soon.

set your LD_LIBRARY_PATH environment variable to point to the directory that contains libpocketsphinx.so.0

example: 

 LD_LIBRARY_PATH=/path/to/pocketsphinxlibs /usr/local/bin/pocketsphinx_continuous

Hello,


The installation of sphinxbase and pocketsphinx run fine and D_LIBRARY_PATH environment variable is set.

When I use the pocketsphinx_tdigits script, it seems to run well but after outputing the configuration (pasted at the end of the post), it outputs no single word since I am speaking (microphone was tested with audacity and works)


Thanks for your help

Audacity test means nothing. Test your microphone with

arecord -f S16_LE -r 8000 -D default > record.wav

instead
