💻 Usage Examples

Basic Usage

Evaluation Commands

1. To evaluate on mozilla - foundation/common_voice_7_0 with split test

python eval.py --model_id hf - test/xls - r - 300m - sv --dataset mozilla - foundation/common_voice_7_0 --config sv - SE --split test

2. To evaluate on speech - recognition - community - v2/dev_data

python eval.py --model_id hf - test/xls - r - 300m - sv --dataset speech - recognition - community - v2/dev_data --config sv --split validation --chunk_length_s 5.0 --stride_length_s 1.0

Advanced Usage

Inference With LM

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


model_id = "hf - test/xls - r - 300m - sv"

sample_iter = iter(load_dataset("mozilla - foundation/common_voice_7_0", "sv - SE", 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
# => "jag lämnade grovjobbet åt honom"
