>Which is the best way and easy to training Julius for "short sentences".

Step 1 one of the VoxForge tutorial provides an explanation of how the Julius/Julian grammar works.

Thank you so much Kmaclean for your answer.

Now, im testing your last Acoustic Model files with my "basic" .grammar & .voca files & my chatterbot. With first tests the accuracy is near 95% with my voice WOW !!.

What do you think about Omnidirectional MICs and Unidirectional MICs? ( button mics ). Which is the best for use with Julius?

Thank you so much!!!

Don't know...

If you can try both out and let us know of your experiences, it would be greatly appreciated.

Hi Ken, me again...

i finished my test with button mics. I dont know why the best accuracy is with Ominidirectional Mic and not with Unidirectional Mic ( noise reduction ) but the difference is Omni: Accuracy ( 90-95% ) and Uni with Noise reduction: Accuracy ( 80-85% ). Very strange results!!!

Ken, how can i test your last Acoustic Model without .grammar & .voca files. Only the acoustic model for continuos dictation.

Another question is ( sorry for my english ). When a phrase is not 100% recognized by Julius and change for example "now are you?" instead "how are you?", my chatterbot fail with the answer. Is it possible to put a recognition level accuracy in Julius?. For example, If the phrase recognized by Julius is under 70%, dont shot it and listen again. ( Sorry again for my english ). I hope that you understand my question.

Thanks in advance Ken,

Mendru

Not unless you want to change Julius... regardless you can do this at your application level by looking at the confidence scores (my post at the end).
