-# Seamless Streaming 
+# SeamlessStreaming
+SeamlessStreaming is a multilingual streaming translation model. It supports:
 
-It is the streaming only model and Seamless is the expressive streaming model.
+- Streaming Automatic Speech Recognition on 96 languages.
+- Simultaneous translation on 101 source languages for speech input.
+- Simultaneous translation on 96 target languages for text output.
+- Simultaneous translation on 36 target languages for speech output.
 
-## Quick start:
+![SeamlessStreaming architecture](streaming_arch.png)
 
-Evaluation can be run with the `streaming_evaluate` CLI.

+| SeamlessStreaming  | 2.5B    | [🤗 Model card](https://huggingface.co/facebook/seamless-streaming) - [monotonic decoder checkpoint](https://huggingface.co/facebook/seamless-streaming/resolve/main/seamless_streaming_monotonic_decoder.pt) - [streaming UnitY2 checkpoint](https://huggingface.co/facebook/seamless-streaming/resolve/main/seamless_streaming_unity.pt)  | [metrics](https://dl.fbaipublicfiles.com/seamless/metrics/streaming/seamless_streaming.zip)  |
 
-We use the `seamless_streaming_unity` for loading the speech encoder and T2U models, and `seamless_streaming_monotonic_decoder` for loading the text decoder for streaming evaluation. This is already set as defaults for the `streaming_evaluate` CLI, but can be overridden using the `--unity-model-name` and  `--monotonic-decoder-model-name` args if required.
+The evaluation data ids for FLEURS, CoVoST2 and CVSS-C can be found [here](https://dl.fbaipublicfiles.com/seamless/metrics/evaluation_data_ids.zip)
 
-Note that the numbers in our paper use single precision floating point format (fp32) for evaluation by setting `--dtype fp32`. Also note that the results from running these evaluations might be slightly different from the results reported in our paper (which will be updated soon with the new results).
 
-### S2TT:
-Set the task to `s2tt` for evaluating the speech-to-text translation part of the SeamlessStreaming model.
+## Evaluating SeamlessStreaming models
+To reproduce our results, or to evaluate using the same metrics over your own test sets, please check out the [Evaluation README here](../../src/seamless_communication/cli/streaming/README.md). Streaming evaluation depends on the SimulEval library.
 
-```bash
-streaming_evaluate --task s2tt --data-file <path_to_data_tsv_file> --audio-root-dir <path_to_audio_root_directory> --output <path_to_evaluation_output_directory> --tgt-lang <3_letter_lang_code>

+## Seamless Streaming demo
+
+### Running on HF spaces
+You can simply duplicate the space to run it. [🤗 HF Space](https://huggingface.co/spaces/facebook/seamless-streaming)
+
+## Running locally
+
+### Install backend seamless_server dependencies
+
+> [!NOTE]
+> Please note: we *do not* recommend running the model on CPU. CPU inference will be slow and introduce noticable delays in the simultaneous translation.
 
-Note: The `--ref-field` can be used to specify the name of the reference column in the dataset.
+> [!NOTE]
+> The example below is for PyTorch stable (2.1.1) and variant cu118. 
+> Check [here](https://pytorch.org/get-started/locally/) to find the torch/torchaudio command for your variant. 
+> Check [here](https://github.com/facebookresearch/fairseq2#variants) to find the fairseq2 command for your variant.
 
-### ASR:
-Set the task to `asr` for evaluating the automatic speech recognition part of the SeamlessStreaming model. Make sure to pass the source language as the `--tgt-lang` arg.
+If running for the first time, create conda environment and install the desired torch version. Then install the rest of the requirements:
+```
+cd seamless_server
+conda create --yes --name smlss_server python=3.8 libsndfile==1.0.31
+conda activate smlss_server
+conda install --yes pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia
+pip install fairseq2 --pre --extra-index-url https://fair.pkg.atmeta.com/fairseq2/whl/nightly/pt2.1.1/cu118
+pip install -r requirements.txt
+```
 
-```bash
-streaming_evaluate --task asr --data-file <path_to_data_tsv_file> --audio-root-dir <path_to_audio_root_directory> --output <path_to_evaluation_output_directory> --tgt-lang <3_letter_source_lang_code> 
+### Install frontend streaming-react-app dependencies
+```
+conda install -c conda-forge nodejs
+cd streaming-react-app
+npm install --global yarn
+yarn
+yarn build  # this will create the dist/ folder
 ```
 
-### S2ST:
 
-#### SeamlessStreaming:
+### Running the server
 
-Set the task to `s2st` for evaluating the speech-to-speech translation part of the SeamlessStreaming model. 
+The server can be run locally with uvicorn below.
+Run the server in dev mode:
 
-```bash
-streaming_evaluate --task s2st --data-file <path_to_data_tsv_file> --audio-root-dir <path_to_audio_root_directory> --output <path_to_evaluation_output_directory> --tgt-lang <3_letter_lang_code>
 ```
+cd seamless_server
+uvicorn app_pubsub:app --reload --host localhost
+```
+
+Run the server in prod mode:
 
-#### Seamless:
-The Seamless model is an unified model for streaming expressive speech-to-speech tranlsation. Use the `--expressive` arg for running evaluation of this unified model.
+```
+cd seamless_server
+uvicorn app_pubsub:app --host 0.0.0.0
+```
+
+To enable additional logging from uvicorn pass `--log-level debug` or `--log-level trace`.
+
+
+### Debuging
+
+If you enable "Server Debug Flag" when starting streaming from the client, this enables extensive debug logging and it saves audio files in /debug folder.
