Media Server 24.2

# ModelVersion

The model to use to convert speech into text.

- `Legacy` uses the IDOL 12.x speech-to-text models. When you choose this option you can configure custom language models and custom word databases.

- `Micro`, `Small`, and `Large` use a new speech-to-text algorithm that was introduced in IDOL 23.2. These provide much better accuracy than the legacy models, especially for English speech. Custom language models and custom word databases are neither required nor supported, because the vocabulary of these models is not limited by their training.

  - The `micro` model is the fastest of the new models, and can be used to process live streams on older or less powerful hardware than the small model.
  - The `small` model is recommended for processing live streams. You can also use this model if you are processing files but prefer shorter processing times than offered by the large model.
  - The `large` model provides maximum accuracy but requires significantly more processing time. This model is not suitable for processing live streams on current hardware.
