# SeamlessM4T Medium |
|
|
|
SeamlessM4T is a collection of models designed to provide high quality translation, allowing people from different |
|
linguistic communities to communicate effortlessly through speech and text. |
|
|
|
SeamlessM4T covers: |
|
- 📥 101 languages for speech input |
|
- ⌨️ 96 Languages for text input/output |
|
- 🗣️ 35 languages for speech output. |
|
|
|
------------------- |
|
|
|
**🌟 SeamlessM4T v2, an improved version of this version with a novel architecture, has been released [here](https://huggingface.co/facebook/seamless-m4t-v2-large).** |
|
|
|
**This new model improves over SeamlessM4T v1 in quality as well as inference speed in speech generation tasks.** |
|
|
|
**SeamlessM4T v2 is also supported by 🤗 Transformers, more on it [in the model card of this new version](https://huggingface.co/facebook/seamless-m4t-v2-large#transformers-usage) or directly in [🤗 Transformers docs](https://huggingface.co/docs/transformers/main/en/model_doc/seamless_m4t_v2).** |
|
|
|
------------------- |
|
|
|
This is the "medium" variant of SeamlessM4T, which enables multiple tasks without relying on multiple separate models: |
|
- Speech-to-speech translation (S2ST) |
|
- Speech-to-text translation (S2TT) |
|
- Text-to-speech translation (T2ST) |
|
- Text-to-text translation (T2TT) |
|
- Automatic speech recognition (ASR) |
|
|

|
|
|
We provide extensive evaluation results of SeamlessM4T models in the [SeamlessM4T](https://arxiv.org/abs/2308.11596) and [Seamless](https://arxiv.org/abs/2312.05187) papers (as averages) in the `metrics` files above. |
|
|
|
## 🤗 Transformers Usage |
|
|
|
First, load the processor and a checkpoint of the model: |
|
|
|
```python |
|
import torchaudio |
|
from transformers import AutoProcessor, SeamlessM4TModel |
|
processor = AutoProcessor.from_pretrained("facebook/hf-seamless-m4t-medium") |
|
model = SeamlessM4TModel.from_pretrained("facebook/hf-seamless-m4t-medium") |
|
``` |
|
|
|
You can seamlessly use this model on text or on audio, to generated either translated text or translated audio. |
|
|
|
Here is how to use the processor to process text and audio: |
|
|
|
```python |
|
# Read an audio file and resample to 16kHz: |
|
audio, orig_freq = torchaudio.load("https://www2.cs.uic.edu/~i101/SoundFiles/preamble10.wav") |
|
audio = torchaudio.functional.resample(audio, orig_freq=orig_freq, new_freq=16_000) # must be a 16 kHz waveform array |
|
audio_inputs = processor(audios=audio, return_tensors="pt") |
|
|
|
# Process some input text as well: |
|
text_inputs = processor(text = "Hello, my dog is cute", src_lang="eng", return_tensors="pt") |
|
``` |
|
|
|
### Speech |
|
|
|
Generate speech in Russian from either text (T2ST) or speech input (S2ST): |
|
|
|
```python |
|
audio_array_from_text = model.generate(**text_inputs, tgt_lang="rus")[0].cpu().numpy().squeeze() |
|
audio_array_from_audio = model.generate(**audio_inputs, tgt_lang="rus")[0].cpu().numpy().squeeze() |
|
``` |
|
|
|
### Text |
|
|
|
Similarly, you can generate translated text from audio files (S2TT) or from text (T2TT, conventionally MT) with the same model. |
|
You only have to pass `generate_speech=False` to [`SeamlessM4TModel.generate`](https://huggingface.co/docs/transformers/main/en/model_doc/seamless_m4t#transformers.SeamlessM4TModel.generate). |
|
|
|
```python |
|
# from audio |
|
output_tokens = model.generate(**audio_inputs, tgt_lang="fra", generate_speech=False) |
|
translated_text_from_audio = processor.decode(output_tokens[0].tolist()[0], skip_special_tokens=True) |
|
|
|
# from text |
|
output_tokens = model.generate(**text_inputs, tgt_lang="fra", generate_speech=False) |
|
translated_text_from_text = processor.decode(output_tokens[0].tolist()[0], skip_special_tokens=True) |
|
``` |
|
|
|
## Seamless_communication |
|
You can also use the seamlessM4T models using the [`seamless_communication` library](https://github.com/facebookresearch/seamless_communication/blob/main/docs/m4t/README.md) |
|
|
|
with either CLI: |
|
```bash |
|
m4t_predict <path_to_input_audio> --task s2st --tgt_lang <tgt_lang> --output_path <path_to_save_audio> --model_name seamlessM4T_medium |
|
``` |
|
or a `Translator` API: |
|
```py |
|
import torch |
|
from seamless_communication.inference import Translator |
|
|
|
# Initialize a Translator object with a multitask model, vocoder on the GPU. |
|
translator = Translator("seamlessM4T_medium", "vocoder_36langs", torch.device("cuda:0"), torch.float16) |
|
text_output, speech_output = translator.predict( |
|
input=<path_to_input_audio>, |
|
task_str="S2ST", |
|
tgt_lang=<tgt_lang>, |
|
text_generation_opts=text_generation_opts, |
|
unit_generation_opts=unit_generation_opts |
|
) |
|
``` |
