    Dear VBWG,

I am sending you some suggestions of new features for a next version of
VoiceXML. I believe that they would be helpful for dialog designers and
that the suggested features are a logical extension of current VoiceXML.

Any comments are welcome.

1. What did you say?
In a real dialog in a noisy environment or when a user is not
concentrated, it can happen that a user does not understand properly a
system prompt and wants the system to repeat it. The last prompt should be
repeated without increasing the prompt counter in order to repeat really
the same prompt. It is not possible to do it in the current version of

I suggest the following solution: Add an atribute to the <reprompt> tag,
which allows to repeat prompts without increasing the prompt counter.

2. detection and handling of multiple fills of one slot
VoiceXML provides no means for detection and handling the situation when a
slot value is re-specified.

In real conversation it can happen that a participant specifies a piece of
information twice with different value. The normal reaction is that the
other participant detects this situation and asks the first one for a
clarification. VoiceXML has no means for doing this.

I suggest the following solution: Define a standard event, e.g.
slotredefinition.slotname that would be thrown in such a case and the old
value would be contained in the _message variable in the <catch> tag's
anonymous scope.

    Best regards

       Pavel Cenek
