Need a response...please

[Raghu]

Hi list,

I am trying to develop a Speech Recognition System which will be able to recognize pilot's commands in a aviation environment.
I am able to tun the offline mode but when i try to run the live mode of the Speech Recognizer, it acts weird.

I have 33 utterances with WSJ, a simple word list grammar, flat linguist, my own dictionary.
Can you please explain me what this means?

The hypothesis text [HYP] is generated by itself.Its not something i spoke on the mike.

And it also generated Align.txt whic has

and type id tag id tag field type field type type exit tunnel tunnel type type thirty id type

The words in capitals are the 33 utterances of my raw files. And the first sentence is the HYP.

Can you please respond to this email?

I am struck here and I need some information to carry on.

Thanks a lot in Advance,

Sincerely,

Raghu.
