Introduction
- We release a new model for Vietnamese speech regconition task.
- We fine-tuned openai/whisper-medium on our new dataset VietSpeech.
Training data
| VSV-1100 | T2S* | CMV14-vi | VIVOS | VLSP2021 | Total |
|---|---|---|---|---|---|
| 1100 hours | 11 hours | 3.04 hours | 13.94 hours | 180 hours | 1308 hours |
* We use a text-to-speech model to generate sentences containing words that do not appear in our dataset.
WER result
| CMV14-vi | VIVOS | VLSP2020-T1 | VLSP2020-T2 | VLSP2021-T1 | VLSP2021-T2 | Bud500 |
|---|---|---|---|---|---|---|

Usage
Inference
from transformers import WhisperProcessor, WhisperForConditionalGeneration
import librosa
# load model and processor
processor = WhisperProcessor.from_pretrained("NhutP/ViWhisper-medium")
model = WhisperForConditionalGeneration.from_pretrained("NhutP/ViWhisper-medium")
prefix_ids = model.generation_config.forced_decoder_ids
model.generation_config.input_ids = prefix_ids
model.generation_config.forced_decoder_ids = None
# load a sample
array, sampling_rate = librosa.load('path_to_audio', sr = 16000) # Load some audio sample
input_features = processor(array, sampling_rate=sampling_rate, return_tensors="pt").input_features
# generate token ids
predicted_ids = model.generate(input_features)
# decode token ids to text
transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)
Use with pipeline
from transformers import pipeline
pipe = pipeline(
"automatic-speech-recognition",
model="NhutP/ViWhisper-medium",
max_new_tokens=128,
chunk_length_s=30,
return_timestamps=False,
device= '...' # 'cpu' or 'cuda'
)
output = pipe(path_to_audio_samplingrate_16000)['text']
