A library of foundational multilingual multimodal AI models from Meta for speech and text translation, including SeamlessM4T, SeamlessExpressive, and SeamlessStreaming. It supports translation across roughly 100 languages with speech-to-text, text-to-speech, and streaming capabilities.

Use cases

• translate speech between 100 languages
• build real-time simultaneous translation
• preserve voice style and prosody across languages
• transcribe streaming audio with multilingual ASR
• run speech-to-speech translation models locally
• experiment with multilingual foundation models in notebooks

When to choose

• you need state-of-the-art multilingual speech or text translation
• you want expressive translation that preserves prosody and voice
• you need streaming/simultaneous translation with low latency
• you want to fine-tune or research multimodal translation models

When to avoid

• you need a lightweight production translation API without GPU resources
• you only need simple text-to-text translation of a few languages
• you require a permissively licensed model for commercial redistribution without checking the custom license
