Features

Here’s what you get with ElevenLabs in your app:
  • 1,000+ voices from the ElevenLabs Voice Library — your users have plenty to choose from
  • 26+ languages supported out of the box
  • Fine-tuning controls — adjust stability, similarity, and style to get the perfect audio output
  • Cloud storage — generated audio is uploaded to Cloudflare R2 storage automatically
  • Database tracking — generation data is stored in the generations table in PostgreSQL
  • Credit usage — each generation reduces the user’s credits (configurable in toolConfig.ts)
The voice fine-tuning settings (stability, similarity, style) let your users really dial in the output. Higher stability gives more consistent results, while lower stability adds more expressiveness and variation.
