[vtp-dev] Problem with PlayPrompt before OptionSet
|
Greetings,
The OptionSet node allows you to configure a grammar for each option. But
what if you want a single high-level grammar for the whole OptionSet (i.e.
"Would you like pizza or spaghetti?"). The pre-built Menu Dialog seems to
handle this by having a PlayPrompt before the OptionSet. However, I am
experiencing a problem with this architecture. If the user speaks during
the PlayPrompt (barges in), no detection is active, because the voice
browser isn't yet processing the OptionSet (<menu>). When the OptionSet
(<menu>) starts up, the user is already mid-utterance. In our case we are
using Loquendo ASR which complains about trying to recognize mid-utterance:
Recognizer Error: "API lasrxRecog in module Loquendo ASR 7.5.2.1 returned
with code -134: User has spoken too soon. Utterance started before
recognition The Voice Detector Module has detected that speech has begun
too early. Sudden energy fall; maybe the user spoke too early. "
Has anyone else seen this problem? What is the suggested approach?
Cheers,
- Brendan
