[Olympus developers 449]: Re: how to integrate olympus/ravenclaw with asterisk - multi user

[Nitin Dhawan]

Thanks. Will definitely have a look.

 

Is there someone who can help us/work with us in the development  of this
interface? We need the entire system - with dialog, NLG, backend, speech,
telephony and Java interface with simultaneous multi user support.

with asterisk - multi user

 

For a telephone interface, you could use a softswitch like freeswitch that
supports multiple sessions (default is 1000) and protocols to communicate
with an application. 

 

We have tried to provide a preliminary interface between the audioserver
component and the freeswitch server. There's a tarball that you can start
from. The freeswitch application writes incoming audio data to a named-pipe
for every new session. This audio data is read by an instance of audioserver
component and forwarded to the recognizer (pocketsphinx).

There is an example application (with example configuration) in the tarball.
It also includes customized audioserver and the pocketsphinx engine. If you
want to rest of the olympus components, you have to figure out how they will
interact with the freeswitch application.

We want to make the system available on the pstn phone system. We have setup
asterisk and can route the calls on extensions. The question is 

a.       How to integrate this with the dialog system. This is regularly
done with systems like Roomline, but the instructions are not very clear.
Here is someone talking about it
http://www.cs.cmu.edu/~jsherwan/research/asterisk.ppt  but its not quite
clear

b.      How to enable multiple people to connect simultaneously over
telephony. I already asked how to enable multiple simultaneous sessions, but
the answer looks quite complicated and non-standard. It's hard to believe
how any commercial systems would be implemented on Ravenclaw without multi
session support being a standard feature.

 

Please help . 

 

We are investing serious efforts in integrating Ravenclaw architecture in
our system with the belief that this is one of the best systems around.
