Cerence Voice Lab is an open, self-service platform for evaluating and integrating voice AI. Test Cerence AI speech recognition and speech synthesis with your own audio, compare performance across languages and deployment targets, and get actionable results in minutes.
Real-world noise and echo make accuracy hard to trust.
Cloud round-trips often break real-time voice interactions.
Global products need real localization beyond one language.
Compliance and IT policy often rule out cloud-only voice AI.
Test on your own audio today, validate on the edge next, and compose complete pipelines after that – same account, same APIs, and growing capability.

Cerence Voice Lab is a voice AI evaluation environment, designed to help teams test, compare, and validate conversational AI technologies before moving into development. It brings together Cerence AI’s speech recognition and speech synthesis capabilities in one platform, allowing you to evaluate performance across different builds and configurations using your own use cases.
Today, Cerence Voice Lab supports ASR (speech-to-text) and TTS (text-to-speech) evaluation, making it easy to test and compare multiple configurations side by side.
Most speech APIs are optimized for clean cloud environments. Cerence AI has spent more than 25 years delivering voice AI in demanding real-world conditions – from road noise and embedded hardware to real-time performance requirements. Cerence Voice Lab lets you evaluate that expertise against your own use case.
No. Cerence Voice Lab is designed for any industry where voice quality, accuracy, and performance matter.
Yes. Upload your own audio samples to test recognition accuracy and voice quality against your actual use case, not a generic demo.
In minutes. Sign up, get an API key, and start testing in the same session – no procurement cycle required.
All connections are encrypted, and access is controlled through individual API keys. For details on how uploaded data is stored and retained, please contact voicelab-support@cerence.com.
Yes. Cerence Voice Lab provides REST and WebSocket APIs, along with documentation and code samples to help you integrate quickly.
Cerence Voice Lab is currently a cloud-based evaluation environment. Edge deployment options are planned as part of our future roadmap.
Bring-your-own-LLM support is planned, enabling you to pair Cerence AI voice quality with the AI stack you already use.
Cerence Voice Lab builds on Cerence AI's 80+ language portfolio. Phase 1 ASR supports 10 languages rolling out in two waves, starting with English (US), German, Mandarin, and Japanese. TTS is initially available in English (US), with additional language voices added as they're production-validated.
Cerence Voice Lab Phase 1 is focused on evaluation and testing. If you're ready to explore a production deployment, our team can help assess your requirements and discuss next steps. Contact voicelab-support@cerence.com to start the conversation.
