Hibiki is a model for streaming speech translation (also known as simultaneous translation). Unlike offline translation—where one waits for the end of the source utterance to start translating--- Hibiki adapts its flow to accumulate just enough context to produce a correct translation in real-time, chunk by chunk. observed · 2026-08-28

Hibiki is a decoder-only model for streaming (simultaneous) speech-to-speech translation, built on the multistream Moshi architecture. It processes source speech in real time and generates target-language speech with optional voice transfer, along with timestamped text translation.
Use cases
- translate live speech in real time while the speaker is still talking
- simultaneous interpretation for meetings or broadcasts
- generate translated speech preserving the original speaker's voice
- produce timestamped text transcripts of a translation as audio streams
- run a speech translation model locally on GPU
When to choose
- you need low-latency, chunk-by-chunk translation rather than waiting for the utterance to end
- you want both audio and text output from a single model
- voice transfer to keep the speaker's voice in the translation matters
- you need a batch-friendly model with simple temperature sampling inference
When to avoid
- you only need offline translation of complete recordings with maximum quality
- your language pair is not supported by the released models
- you have no GPU and need fast real-time performance
- you need text-only document translation
