Voice Lab is the dedicated workspace for testing and debugging voice experiences.
What It Covers
Voice Lab is much broader than a simple microphone test. Depending on your setup, it can help you:
- edit voice-related configuration
- control retrieval behavior during voice tests
- choose microphone and speaker devices
- run live voice sessions
- inspect transcripts and tool calls
- compare or sync configuration with ElevenLabs
Plain-Language Definitions
| Term | What it means here |
|---|---|
| Tool call | A live action the voice agent triggered during a session |
| ElevenLabs sync | Pushing or comparing Kravos.ai voice settings with the ElevenLabs side |
| Config drift | Kravos.ai and ElevenLabs no longer match, so behavior differs between the two |
When To Use Voice Lab Instead Of Playground
Use Voice Lab when the question is about:
- audio input or output
- latency in voice interactions
- live tool calls during voice sessions
- ElevenLabs agent sync and config drift
Use Playground when the question is mainly about text quality or retrieval logic.
Typical Voice Validation Flow
- confirm the agent's voice defaults in Agent Settings
- open Voice Lab and choose the correct devices
- run a short live session with common customer intents
- inspect transcript quality and tool calls
- confirm the voice setup matches your ElevenLabs configuration if you use it
Best Practices
- test in the same environment your users will use, not only on a perfect office setup
- validate both success paths and interruption-heavy paths
- inspect tool-call latency when voice feels slow
- keep voice prompts and retrieval expectations aligned with text behavior
Troubleshooting
Voice feels slow
- inspect tool calls and their duration
- compare retrieval latency with Playground
- confirm the issue is not device or network related
Transcript quality is poor
- test a different microphone and environment
- check whether the spoken language matches the configured expectation
- compare multiple sessions so you do not overreact to one noisy run
ElevenLabs behavior does not match Kravos.ai
- compare the current config in Voice Lab
- check for sync drift before changing prompts blindly
- re-run a short validation session after syncing
