voice detection problem

[shanthint@paydq.com]

We have a plum voice server. It seems like it has voice detection problem. It can't even recognize the word 'YES' for input.
And also it is taking a long pause after taking the input.
Do we need to do anything with the server like changing some configuration setup?
If we need to change the configuration, I can send the email with my CustomerID to plum support.

here is the sample code:
<field name="form1">

<grammar type="application/x-jsgf" mode="voice">
^(yes|no|yeah|sure|S)$
</grammar>

<prompt>

<sentence>You entered some number</sentence>

<sentence>To confirm this , say yes. </sentence>
<sentence>To cancel this , say No.</sentence>

</prompt>

</field>

Thanks in advance.

Hi,

We've just tested your sample IVR code and it works fine for us:

Code: Select all

<?xml version="1.0"?>
<vxml version="2.0">
<form>
<field name="form1">

<grammar type="application/x-jsgf" mode="voice">
^(yes|no|yeah|sure|S)$
</grammar>

<prompt>

<sentence>You entered some number</sentence>

<sentence>To confirm this , say yes. </sentence>
<sentence>To cancel this , say No.</sentence>

</prompt>

<filled>
  You said <value expr="form1"/>.
</filled>

</field> 
</form>
</vxml>

Can you post an IVR call log where this IVR issue occurs and provide us with more details on how to produce this IVR error?

Hello,

It can recognize the voice only if we have the receiver near by our mouth.
If we talk on the speaker phone or having receiver far from our voice or talking loud and also in the noisy environment it can not get the input. sometimes we have to say that two or three times to get it work.

I have
<property name="confidencelevel" value="0.5"/> <property name="incompletetimeout" value="2s"/> <property name="recordcall" value="true"/>
<property name="sensitivity" value="0.5"/>
<property name="interdigittimeout" value="300ms"/>
<property name="timeout" value="3s"/>
<property name="inputmodes" value="dtmf voice"/>

Do these setup to do anything with that?

I provide a part of the call log when it occurs.Please let me know if
this is not enough to debug.

Hi,

You could try lowering the sensitivity to a value like 0.3 to account for the noisy environment. You could also make all of your prompts non-bargeable to prevent <nomatch> messages from occurring.

Code: Select all

<?xml version="1.0"?>
<vxml version="2.0">
<form>

<property name="sensitivity" value="0.3"/>

<field name="form1">

<grammar type="application/x-jsgf" mode="voice">
^(yes|no|yeah|sure|S)$
</grammar>

<prompt bargein="false">

<sentence>You entered some number</sentence>

<sentence>To confirm this , say yes. </sentence>
<sentence>To cancel this , say No.</sentence>

</prompt>

<filled>
  You said <value expr="form1"/>.
</filled>

</field>
</form>
</vxml> 

Hope this IVR code helps.
