What is speech recognition in customer service?

It converts customer and agent audio into text that can support live captions, agent assistance, routing, notes, search or post-call analytics.

Should a contact center use streaming or batch transcription?

Use streaming for live workflows, batch for post-call analysis, or a hybrid when live speed and final completeness have different requirements.

How should transcription accuracy be measured?

Measure representative word error rate, critical-term accuracy, speaker attribution and the actual downstream task outcome across languages and conditions.

Can confidence scores drive automation?

Only after local calibration. Provider confidence may be missing or inconsistent and should be combined with context, consequence and fallback.

How can product names be recognized better?

Use supported phrase hints or custom vocabulary, version the terminology list and test improvement without causing ordinary-word substitutions.

What should happen when transcription fails?

The customer-service workflow should continue through a tested non-speech-recognition fallback without losing the call or granting an unsafe default action.

Should transcripts be retained indefinitely?

No. Set purpose-specific retention for audio, transcripts, analytics and review evidence, then automate deletion across primary stores and vendor copies.
