Monsoon-Whisper-Medium-Gigaspeech2

Monsoon-Whisper-Medium-GigaSpeech2 is a 🇹🇭 Thai Automatic Speech Recognition (ASR) model. It is based on Whisper-Medium and fine-tuned on GigaSpeech2.

Originally developed as a scale experiment for research on emergent capabilities in ASR tasks. It performs well in the wild, including with audio sourced from YouTube and in noisy environments.

More details can be found in our Typhoon-Audio Release Blog.

Model Description

Model type: Whisper Medium.
Requirement: transformers 4.38.0 or newer.
Primary Language(s): Thai 🇹🇭
License: Apache 2.0

Usage Example

python

from transformers import WhisperProcessor, WhisperForConditionalGeneration
import torchaudio
import torch

model_path = "scb10x/monsoon-whisper-medium-gigaspeech2"
device = "cuda"
filepath = 'audio.wav'

processor = WhisperProcessor.from_pretrained(model_path)
model = WhisperForConditionalGeneration.from_pretrained(
    model_path, torch_dtype=torch.bfloat16
)
model.to(device)
model.eval()

model.config.forced_decoder_ids = processor.get_decoder_prompt_ids(
    language="th", task="transcribe"
)
array, sr = torchaudio.load(filepath)
input_features = (
    processor(array, sampling_rate=sr, return_tensors="pt")
    .to(device)
    .to(torch.bfloat16)
    .input_features
)
predicted_ids = model.generate(input_features)
transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)
print(transcription)
