S2t Wav2vec2 Large En Ar

🚀 S2T2-Wav2Vec2-CoVoST2-EN-AR-ST

s2t-wav2vec2-large-en-ar is a Speech to Text Transformer model trained for end-to-end Speech Translation (ST). It offers an efficient solution for translating English speech directly into Arabic text.

🚀 Quick Start

This model can be used for end-to-end English speech to Arabic text translation. You can use the model directly via the ASR pipeline or step - by - step as shown in the usage examples below.

✨ Features

• End - to - End Translation: Capable of performing direct English speech to Arabic text translation.
• Transformer - Based: Utilizes a transformer - based seq2seq (speech encoder - decoder) architecture.
• Pretrained Encoder: Employs a pretrained Wav2Vec2 as the encoder.

📦 Installation

💻 Usage Examples

Basic Usage

from datasets import load_dataset
from transformers import pipeline

librispeech_en = load_dataset("patrickvonplaten/librispeech_asr_dummy", "clean", split="validation")
asr = pipeline("automatic-speech-recognition", model="facebook/s2t-wav2vec2-large-en-ar", feature_extractor="facebook/s2t-wav2vec2-large-en-ar")

translation = asr(librispeech_en[0]["file"])

Advanced Usage

import torch
from transformers import Speech2Text2Processor, SpeechEncoderDecoder
from datasets import load_dataset

import soundfile as sf
model = SpeechEncoderDecoder.from_pretrained("facebook/s2t-wav2vec2-large-en-ar")
processor = Speech2Text2Processor.from_pretrained("facebook/s2t-wav2vec2-large-en-ar")

def map_to_array(batch):
    speech, _ = sf.read(batch["file"])
    batch["speech"] = speech
    return batch
    
ds = load_dataset("patrickvonplaten/librispeech_asr_dummy", "clean", split="validation")
ds = ds.map(map_to_array)

inputs = processor(ds["speech"][0], sampling_rate=16_000, return_tensors="pt")
generated_ids = model.generate(input_ids=inputs["input_features"], attention_mask=inputs["attention_mask"])
transcription = processor.batch_decode(generated_ids)

📚 Documentation

Model description

S2T2 is a transformer - based seq2seq (speech encoder - decoder) model designed for end - to - end Automatic Speech Recognition (ASR) and Speech Translation (ST). It uses a pretrained Wav2Vec2 as the encoder and a transformer - based decoder. The model is trained with standard autoregressive cross - entropy loss and generates the translations autoregressively.

Intended uses & limitations

This model can be used for end - to - end English speech to Arabic text translation. See the model hub to look for other S2T2 checkpoints.

How to use

As this is a standard sequence to sequence transformer model, you can use the generate method to generate the transcripts by passing the speech features to the model.

🔧 Technical Details

The S2T2 model was proposed in Large - Scale Self - and Semi - Supervised Learning for Speech Translation and officially released in Fairseq.

📄 License

This model is licensed under the MIT license.
