[Olympus developers 346]: Re: problems with Tutorial 1 and 2

[Alex Rudnicky]

Your recognition is very poor and rather degenerate (the same words keep showing up). This usually means that the stuff getting to the decoder is corrupted in some way (though a bad language model might also do it). The things to check include:

1) is the input through the mic that you intended? (ie, headset or bezel; headset is more reliable.)
2) is the sampling rate correct?
3) is the signal too loud/soft?

I would probably use Audacity on one of the logged waveforms to make sure that the signal looks ok. Check both waveform for amplitude (clipping is particularly harmful) and spectrum (it should be reasonably noise-free and match the nominal bandwidth of your acoustic models).

Subject: [Olympus developers 345]: problems with Tutorial 1 and 2

Dear Olympus developers:

I installed Olympus and all the prerequisite programs, and then tried Tutorial 1 and 2. I don't think they worked properly.

Yesterday in Tutorial 1 I got (I am using Flite):

S:  Welcome to MyBus.
S:  Where are you leaving from?
U(0.00000): A AGAIN
U(tty):
S:  Where are you leaving from?
U(0.00000): .WHEN. WHEN IS THE ONE
U(tty):
S:  Where are you leaving from?
U(0.00000): A .NEW. HILL
U(tty):
S:  Where are you leaving from?
U(0.84404): A NEW QUERY
U(tty):
S:  Where are you leaving from?

U(0.00000): A NEW
U(tty):
S:  Where are you leaving from?
U(0.00000): A NEW

S:  Where are you leaving from?

I wasn't able to enter textual input.



Today in Tutorial 1 I got:

New session starting at 09:59:27.916
------------------------------------

S:  Welcome to MyBus.

S:  Where are you leaving from?

U(0.00000): A
U(tty):

U(0.00000): A
U(tty):
S:  Where are you leaving from?
downtown

S:  Where are you going?
the airport

S:  Just a minute. Let me check that for you.

U(0.00000): THE
U(tty):

My BusDM got stopped by itself.



In tutorial 2, I am getting:

Opened listener on port 11001
Accepted connection from 127.0.0.1 (socket 140) init_session

1. I was wondering if I installed something incorrectly or what the problem may be.

2. Also, how do you I modify one of the tutorials, for example Tutorial 1, to create my own "dialog system"?

Thank you.

Tetyana
