# Languages

Speech-to-text supports the same languages for both [realtime](realtime.md) and [prerecorded](prerecorded.md) transcription.

Pass the `language` query parameter whenever you know the language ahead of time — pinning the language produces better transcription quality than auto-detect. When omitted, the server auto-detects each utterance independently, which is less reliable for short utterances.
