My reply:

Hi Craig,

Thanks for the offer! 

This would be a great resource in itself for speech research purposes. 

However, if we were to use these one-sided telephone conversations to train acoustic models, they would need to be transcribed.  This is a very time consuming process at present.  There are papers that discuss assisted transcription, but with current open source technology, it still requires a fair bit of manual work to get this done.

I would like to post this thread in the VoxForge forum to see what others think.  Please let me know if that is OK.

Craig's last reply:

Hi Ken

Thanks for your reply, so if we had the full converstation it would be more useful?

I want to help in what ever way i can, im happy to provide resources ie server for doing any processing if required.  The only thing is for client security is to do the processing inside our network.

I would also be happy to put some physical resource in place if we need to transcribe conversations, however this will of course reduce the volumes we can deal with.

I just feel there is a resource that should be used.  I have no problems with posting in the forum.


Any comments or feedback are encouraged and welcome.

Did we ever get this added.  I definitely.would transcribe as part of the open source project.   If not added yet, is offer still on the table?   Also yes the whole conversation would be best for transcription.
