What you’ll need
You don't need to be a developer to set up this LMNT and Relevance AI integration. Follow this simple guide to get started:
- A Relevance AI account
- An LMNT account with access to the workspace and projects you'd like to use
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The LMNT and Relevance AI integration utilizes secure OAuth authentication, ensuring that only authorized applications can create and manage custom AI voices. This integration allows developers to leverage LMNT's advanced text-to-speech capabilities while Relevance AI automates the workflow, handling API operations seamlessly in the background—eliminating concerns about errors, formatting, or limits.
With built-in validation and flexible voice customization options, you can create high-quality speech synthesis from text, ensuring that your applications deliver natural-sounding audio. The integration supports multiple audio formats and provides a straightforward API interface for generating speech, making it easy to implement in various projects.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

To get the most out of the LMNT + Relevance AI integration without writing code:
- Start with high-quality audio samples: Ensure your voice samples are clear and free from background noise for optimal voice creation.
- Utilize voice enhancement: Enable enhancement features for noisy audio samples to improve the quality of the generated voice.
- Keep file sizes manageable: Limit individual audio files to under 20MB to ensure smooth processing during voice creation.
- Test with shorter text segments: When generating speech, start with smaller text inputs to validate the output before scaling up.
- Monitor API usage: Be aware of rate limits and implement caching for frequently used voices to optimize performance.
