I'm not sure if this is a development issue or a platform issue. I am looking for a way to speed up the transition from one field to the next. Below is a sample of my code. The transition between the access code confirmation and the password field takes from 1 to 2 seconds. This seems to be the case with other field -> confirmation -> field transitions. Is there anything I can do to speed these up?
Thanks!

Hi,

Do you have a global property such as interdigittimeout in your IVR script?

i.e. This might be the reason why you are experiencing a 2s delay between the confirmation and password field.

To avoid this, you could try setting your IVR properties within local scopes.

My understanding of interdigittimeout was the time it waited for another digit to proceed on to the <filled> section. These are my properties:
<property name="voicename" value="Jennifer"/>
<property name="inputmodes" value="dtmf"/>
<property name="termchar" value="#"/>
<property name="timeout" value="3s"/>
<property name="interdigittimeout" value="2s"/>
<property name="scriptmaxage" value="0s"/>
<property name="documentmaxage" value="0s"/>
<property name="sensitivity" value="0.0"/>

If I set a locally scoped property for interdigittimeout to 0 seconds would this take precedence over the root document's interdigittimeout?
Thanks!

Here's a link that further describes the IVR attribute of how the timing for interdigittimeout works: http://www.w3.org/TR/voicexml20/#dmlATiming

And yes, if you set a locally scoped property for interdigittimeout to a small value such as 10ms or 0s, it would take precedence over the root document's interdigittimeout.

I tried your suggestion and set the confirmation forms interdigittimeout to 0s. It seems like it might be a little faster now, but there is still a little delay switching back from a confirmation to the main form. Anything we can do about that?

Hi,

We've found that using an interdigittimeout value of 10ms works pretty well. There is almost no delay between the confirmation and main form after entering a DTMF-2 key. The following IVR code example:
