Announcements are played repeatedly in the Automatic Speech Recognition (ASR) service.
1. Listen to the ASR announcement and evaluate the duration, for example, 15 seconds.
2. Extend the timeout interval upon no speech input to a larger value, for example, 20 seconds. The value must be larger than the ASR announcement duration.
SET ASRPARA: NIT=20;
3. If the fault still persists, obtain help through the channels described in Help Channels.
In the ASR service, the default timeout interval upon no speech input is only 10 seconds, which is too short. If no speech is detected within 10 seconds after the IVR flow plays an announcement, the ASR service times out and returns a failure message. At this time, the IVR flow re-plays the announcement as preset.
