2. Click on the "Audio" tab
3. Update settings
   - Speech-to-Text Engine: OpenAI

### Using environment variables (Docker Compose)

!!! warning

    This doesn't seem to work when you've previously used the UI to set the STT engine.

```yaml
# NOTE: Some parts of the file are omitted for brevity.
services:
  open-webui:
    image: ghcr.io/open-webui/open-webui:main
    ...
    environment:
      ...
      # Environment variables are documented here https://docs.openwebui.com/getting-started/env-configuration#speech-to-text
