Example speech recognition application in python.

|
|

|
|
How to make this work:
|
||
|
|
|
||
|
|
* Get mod_openmrcp working along with an MRCP asr server
|
||
|
|
* Add /usr/src/freeswitch/scripts or equivalent to your PYTHONPATH
|
||
|
|
* Restart freeswitch
|
||
|
|
* Create $GRAMMAR_ROOT/mainmenu.xml from contents in mainmenu() comments
