# What languages are supported for Streaming Speech-to-text?

Language support for Real-time STT depends on the model you select. AssemblyAI offers several streaming models with different language capabilities:

## Choosing the Right Model

* If you need real-time transcription in a language beyond EN/ES/DE/FR/PT/IT (for example Japanese, Chinese, Hindi, Arabic, or Hebrew), use [Universal-3.5 Pro Streaming](/streaming/select-the-speech-model) (`universal-3-5-pro`, Preview).
* If you need the highest accuracy with multilingual code switching support across EN/ES/DE/FR/PT/IT, use [Universal-3 Pro Streaming](/streaming/getting-started/transcribe-streaming-audio) (`u3-rt-pro`).
* If you only need English transcription at the lowest cost, use Universal-Streaming English (`universal-streaming-english`).
* If you need multilingual support at a lower cost, use Universal-Streaming Multilingual (`universal-streaming-multilingual`).

For more details on model selection, see the [Model selection](/streaming/select-the-speech-model) page.

## Difference From Pre-recorded STT

It's important to note that the `language_code` parameter mentioned in some AssemblyAI documentation applies to the Pre-recorded STT feature, not the Streaming Transcription feature. For real-time STT, you specify the model using the `speech_model` parameter.
