Confidence Level, Opera Voice Log

Two questions hopefully some knows the answers to:

Is it possible to programatically get access to the confidence level 
that is returned from the speech engine? More specifically, I want to be 
able to tell what the confidence level is on a particual field. In the 
X+V standard it mentions something to this effect but does not go into 
detail on how to do it... not that I can find anyway.

And, does anyone know where I can find the voice log while using Opera?

Thanks!

Hello!

Yes, it is possible.

<form>

<field name="lily">
<grammar src="flowers.gram" />

<prompt>Say something to me</prompt>

<filled>
<value expr="alert(application.lastresult$.confidence)" />
</filled>

</field>

</form>

The above form will show you in an alert the confidence level of the  
matched utterance.

The idea is that the UA generates shadow variables during run time.  
application.lastresult$ is always the last matched field. Such a shadow  
variable contains:

- .confidence = the level of confidence of the match. 0.0 being the lowest  
and 1.0 the highest value.
- .utterance = the exact utterance matched, e.g. "the blue lily".
- .interpretation = the object whiched resulted from the semantic  
interpretation tags. It can be something like {flower: "lily", color: 

"#00f"}. It all depends on your flowers.gram-mar.

If you have several fields, you can use application.lily$.confidence. As  
you noticed, you only have to use the field_name$ instead of lastresult$.

For more information, read:

As for the voice log: it is available in Tools > Advanced > Error console.
 
However, you must first enable voice logging. To do so, go to Tools >  
Preferences > Advanced > Voice > Details. There's a drop down which
allows  
you to select the level of logging for voice. Make sure you use the latest  
Opera 9.

Good luck and have fun.

Is it possible to record what a user speaks into a <vxml:field>?

Some examples I see use a script to do this, but I have never seen 
anyone do it while also in a field.
