Introduction
This model is OpenAI Whisper large-v3, finetuned on ~770 hours of manually created subtitles from Estonian TV (ETV). Therefore, this model does not always create verbatim (word-by-word) subtitles but often rephrases the sentences and compresses text, especially in the case of spontaneous speech, hestitations, repetitions, etc. However, the length of the generated text chunks almost always conforms to the ETV subtitle requirements (48 characters per line).
Usage
It's a finetuned vesion of Whisper large-v3-turbo and can be therefore used via Hugging Face 🤗 Transformers. To run the model, first install the Transformers library. For this example, we'll also install 🤗 Accelerate to reduce the model loading time:
pip install --upgrade pip
pip install --upgrade transformers accelerate
The model can be used with the pipeline
class to transcribe audios of arbitrary length:
import torch
from transformers import AutoModelForSpeechSeq2Seq, AutoProcessor, pipeline
from datasets import load_dataset
device = "cuda:0" if torch.cuda.is_available() else "cpu"
torch_dtype = torch.float16 if torch.cuda.is_available() else torch.float32
model_id = "TalTechNLP/whisper-large-v3-et-subs"
model = AutoModelForSpeechSeq2Seq.from_pretrained(
model_id, torch_dtype=torch_dtype, low_cpu_mem_usage=True, use_safetensors=True
)
model.to(device)
processor = AutoProcessor.from_pretrained(model_id)
pipe = pipeline(
"automatic-speech-recognition",
model=model,
tokenizer=processor.tokenizer,
feature_extractor=processor.feature_extractor,
torch_dtype=torch_dtype,
device=device,
)
audio = "sample.mp3"
result = pipe(sample, generate_kwargs={"task": "transcribe", "language": "et"})
print(result)
