# Wav2Vec2-BERT - Alvin
|
||
|
|
|
||
|
|
This model is a fine-tuned version of [facebook/w2v-bert-2.0](https://huggingface.co/facebook/w2v-bert-2.0). This has a CER of 10.27 on Common Voice 16 (yue) test set (without punctuations).
|
||
|
|
|
||
|
|
## Training and evaluation data
|
||
|
|
For training, three datasets were used:
|
||
|
|
- Common Voice 16 `zh-HK` and `yue` Train Set
|
||
|
|
- CantoMap: Winterstein, Grégoire, Tang, Carmen and Lai, Regine (2020) "CantoMap: a Hong Kong Cantonese MapTask Corpus", in Proceedings of The 12th Language Resources and Evaluation Conference, Marseille: European Language Resources Association, p. 2899-2906.
|
||
|
|
- Cantonse-ASR: Yu, Tiezheng, Frieske, Rita, Xu, Peng, Cahyawijaya, Samuel, Yiu, Cheuk Tung, Lovenia, Holy, Dai, Wenliang, Barezi, Elham, Chen, Qifeng, Ma, Xiaojuan, Shi, Bertram, Fung, Pascale (2022) "Automatic Speech Recognition Datasets in Cantonese: A Survey and New Dataset", 2022.

|
||
|
|
```
|
||
|
|
from transformers import pipeline
|
||
|
|
bert_asr = pipeline(

||
|
|
"automatic-speech-recognition", model="alvanlii/wav2vec2-BERT-cantonese", device="cuda"
|
||
|
|
)
|
||
|
|
text = pipe(file)["text"]
|
||
|
|
```
|
||
|
|
or
|
||
|
|
```
|
||
|
|
import torch

|
|
||
|
|
model_name = "alvanlii/wav2vec2-BERT-cantonese"
|
||
|
|
|
||
|
|
asr_model = AutoModelForCTC.from_pretrained(model_name).to(device)
|
||
|
|
processor = Wav2Vec2BertProcessor.from_pretrained(model_name)
|
||
|
|
|
||
|
|
audio_input, _ = sf.read(file)
|
||
|
|
|
||
|
|
inputs = processor([audio_input], sampling_rate=16_000).input_features
|
||
|
|
features = torch.tensor(inputs)
|
||
|
|
|
||
|
|
with torch.no_grad():
|
||
|
|
logits = asr_model(features).logits
|
||
|
|
|
||
|
|
predicted_ids = torch.argmax(logits, dim=-1)
|
||
|
|
predictions = processor.batch_decode(predicted_ids, skip_special_tokens=True)
|
||
|
|
```
