Load model & processor

model_name = "nguyenvulebinh/wav2vec2-base-vi-vlsp2020" model = SourceFileLoader("model", cached_path(hf_bucket_url(model_name,filename="model_handling.py"))).load_module().Wav2Vec2ForCTC.from_pretrained(model_name) processor = Wav2Vec2ProcessorWithLM.from_pretrained(model_name)

Load an example audio (16k)

audio, sample_rate = torchaudio.load(cached_path(hf_bucket_url(model_name, filename="t2_0000006682.wav"))) input_data = processor.feature_extractor(audio[0], sampling_rate=16000, return_tensors='pt')

Infer

output = model(**input_data)

Output transcript without LM

print(processor.tokenizer.decode(output.logits.argmax(dim=-1)[0].detach().cpu().numpy()))

Output transcript with LM

print(processor.decode(output.logits.cpu().detach().numpy()[0], beam_width=100).text)
