# ModelVersion

The model to use to convert speech into text.

- The `micro` model is the fastest. Use this model if you want to prioritize speed over accuracy, or if you need to process live streams without GPU acceleration.
- The `small` model provides a good balance between accuracy and performance for English speech.
- The `medium` model provides a significant increase in accuracy for non-English speech and a modest increase in accuracy for English, at the cost of greater memory requirements and longer processing times.
- The `large` model provides maximum accuracy for non-English speech. This model is not available for English. If you specify English (for example by setting LanguagePack to `ENUK`), Media Server uses the medium model instead.
