Wav2vec2 Large Xls R 300m Urdu

🚀 XLS-R-300M - Urdu

This is a fine - tuned model for automatic speech recognition on the Urdu language, based on the pre - trained wav2vec2 - xls - r - 300m model.

🚀 Quick Start

This model is a fine - tuned version of facebook/wav2vec2-xls-r-300m on the MOZILLA - FOUNDATION/COMMON_VOICE_7_0 - -UR dataset. It achieves the following results on the evaluation set:

• Loss: NA
• Wer: NA

✨ Features

• Tags: automatic - speech - recognition, generated_from_trainer, hf - asr - leaderboard, model_for_talk, mozilla - foundation/common_voice_7_0, robust - speech - event, ur
• Datasets: mozilla - foundation/common_voice_7_0

💻 Usage Examples

Basic Usage

import torch
from datasets import load_dataset
from transformers import AutoModelForCTC, AutoProcessor
import torchaudio.functional as F


model_id = "infinitejoy/wav2vec2-large-xls-r-300m-urdu"

sample_iter = iter(load_dataset("mozilla-foundation/common_voice_7_0", "ur", split="test", streaming=True, use_auth_token=True))

sample = next(sample_iter)
resampled_audio = F.resample(torch.tensor(sample["audio"]["array"]), 48_000, 16_000).numpy()

model = AutoModelForCTC.from_pretrained(model_id)
processor = AutoProcessor.from_pretrained(model_id)

input_values = processor(resampled_audio, return_tensors="pt").input_values

with torch.no_grad():
    logits = model(input_values).logits

transcription = processor.batch_decode(logits.numpy()).text

Advanced Usage
