Code for ACL 2024 paper "StreamSpeech: Simultaneous Speech-to-Speech Translation with Multi-task Learning".
🎧 Listen to StreamSpeech's translated speech 🎧
💡Highlight:
- StreamSpeech achieves SOTA performance on both offline and simultaneous speech-to-speech translation.
- StreamSpeech performs streaming ASR, simultaneous speech-to-text translation and simultaneous speech-to-speech translation via an "All in One" seamless model.
- StreamSpeech can present intermediate results (i.e., ASR or translation results) during simultaneous translation, offering a more comprehensive low-latency communication experience.
- [06.17] Add Web GUI demo, now you can experience StreamSpeech in your local browser.
- [06.05] Paper, code, models and demo of StreamSpeech are available!
- Offline: Speech Recognition (ASR)✅, Speech-to-Text Translation (S2TT)✅, Speech-to-Speech Translation (S2ST)✅, Speech Synthesis (TTS)✅
- Simultaneous: Streaming ASR✅, Simultaneous S2TT✅, Simultaneous S2ST✅, Real-time TTS✅ under any latency (with one model)

Simultaneously provide ASR, translation, and synthesis results via a seamless model
Speech Input: example/wavs/common_voice_fr_17301936.mp3
Transcription (ground truth): jai donc lexpérience des années passées jen dirai un mot tout à lheure
Translation (ground truth): i therefore have the experience of the passed years i'll say a few words about that later

Replace /data/zhangshaolei/StreamSpeech in files configs/fr-en/config_gcmvn.yaml and configs/fr-en/config_mtl_asr_st_ctcst.yaml with your local address of StreamSpeech repo.
Prepare test data following SimulEval format. example/ provides an example:
- wav_list.txt: Each line records the path of a source speech.
- target.txt: Each line records the reference text, e.g., target translation or source transcription (used to calculate the metrics).
Run these scripts to inference StreamSpeech on streaming ASR, simultaneous S2TT and simultaneous S2ST.
--source-segment-size: set the chunk size (millisecond) to any value to control the latency
Simultaneous Speech-to-Speech Translation
--output-asr-translation: whether to output the intermediate ASR and translated text results during simultaneous speech-to-speech translation.

Tip
The train_scripts/ and test_scripts/ in directory --user-dir give the training and testing scripts for each model.
Refer to official repo of UnitY, Translatotron 2, HMT and DiSeg for more details.
Follow pred.offline-s2st.sh to evaluate the offline performance of StreamSpeech on ASR, S2TT and S2ST.
A trained StreamSpeech model can be used for streaming ASR, simultaneous speech-to-text translation and simultaneous speech-to-speech translation. We provide agent/ for these three tasks:
agent/speech_to_speech.streamspeech.agent.py: simultaneous speech-to-speech translationagent/speech_to_text.s2tt.streamspeech.agent.py: simultaneous speech-to-text translationagent/speech_to_text.asr.streamspeech.agent.py: streaming ASR
Follow simuleval.simul-s2st.sh, simuleval.simul-s2tt.sh, simuleval.streaming-asr.sh to evaluate StreamSpeech.
Our project page (https://ictnlp.github.io/StreamSpeech-site/) provides some translated speech generated by StreamSpeech, listen to it 🎧.
