Tuning Voice Gateway

Ensure seamless communication between callers, IBM® Voice Gateway, and Watson services by tuning Voice Gateway performance.

• Improving speech-to-text processing accuracy

To improve the accuracy of speech-to-text processing and reduce unwanted barge-ins, you can change the Speech to Text confidence score threshold and suppress echoes from Text to Speech playback.

• Reducing response time to the Text to Speech service

To reduce the response time from the Text to Speech service, you can configure the Media Relay to cache responses from the Text to Speech service, which results in quicker responses to the caller.

• Enabling Differentiated Services

To provide a better quality of service, enabling differentiated services guarantees delivery and provides low latency for voice over IP traffic.
