wav2vec2-xlsr-ft-cy-en

An acoustic encoder model for Welsh and English speech recognition, fine-tuned from facebook/wav2vec2-large-xlsr-53 using transcribed spontaneous speech from techiaith/banc-trawsgrifiadau-bangor (v24.01) as well as Welsh and English speech data derived from version 16.1 the Common Voice datasets techiaith/commonvoice_16_1_en_cy

Usage

The wav2vec2-xlsr-ft-cy-en model can be used directly as follows:

import torch
import torchaudio
import librosa

from transformers import Wav2Vec2ForCTC, Wav2Vec2Processor

processor = Wav2Vec2Processor.from_pretrained("techiaith/wav2vec2-xlsr-ft-cy-en")
model = Wav2Vec2ForCTC.from_pretrained("techiaith/wav2vec2-xlsr-ft-cy-en")

audio, rate = librosa.load(audio_file, sr=16000)

inputs = processor(audio, sampling_rate=16_000, return_tensors="pt", padding=True)

with torch.no_grad():
  tlogits = model(inputs.input_values, attention_mask=inputs.attention_mask).logits

# greedy decoding
predicted_ids = torch.argmax(logits, dim=-1)

print("Prediction:", processor.batch_decode(predicted_ids))
