bw problem 2

[breno]

hi..its me again...i wrote about a problem that im having but I think i wasnt very clear about my problem....so Im writing again...

Im following the steps from the sphinx manual to training my database...Im using the CMU CENSUS (an4) DATABASE that i got from the sphinx site (www.cmusphinx.org).
i`m following step by step the sphinx manual :
-I create de CI model definition
-I create de topology file
-I did the FLAT INITIALIZATION OF CI MODEL PARAMETERS

but after that , when i`m on the step TRAINING CONTEXT INDEPENDENT MODELS, and i have to run the BW I got a error :

i would apreciate any help

Breno,

I can't quite grasp what your problem is. If you're training context independent models, then it's normal to get messages saying that multiphones (e.g. triphones) couldn't be found. They're are created in subsequent steps. So, the messages you're getting are expected.

Did you get any messages marked WARNING or ERROR? Does the program stop after printing the messages above. or does it go on? If it stops, there isn't enough information to find out where the problem is. If it goes on, the message "no multiphones defined, no conversion done" is expected.

Hope this helps,
