Install

pip install pythaiasr

For Wav2Vec2 with language model: if you want to use wannaphong/wav2vec2-large-xlsr-53-th-cv8-* model with language model, you needs to install by the step.

pip install pythaiasr[lm]
pip install https://github.com/kpu/kenlm/archive/refs/heads/master.zip

Usage

from pythaiasr import asr

file = "a.wav"
print(asr(file))

API

asr(data: str, model: str = _model_name, lm: bool=False, device: str=None, sampling_rate: int=16_000)

• data: path of sound file or numpy array of the voice
• model: The ASR model
• lm: Use language model (except airesearch/wav2vec2-large-xlsr-53-th model)
• device: device
• sampling_rate: The sample rate
• return: thai text from ASR

Options for model

• airesearch/wav2vec2-large-xlsr-53-th (default) - AI RESEARCH - PyThaiNLP model
• wannaphong/wav2vec2-large-xlsr-53-th-cv8-newmm - Thai Wav2Vec2 with CommonVoice V8 (newmm tokenizer)
• wannaphong/wav2vec2-large-xlsr-53-th-cv8-deepcut - Thai Wav2Vec2 with CommonVoice V8 (deepcut tokenizer)

You can read about models from the list:

• airesearch/wav2vec2-large-xlsr-53-th - AI RESEARCH - PyThaiNLP model
• annaphong/wav2vec2-large-xlsr-53-th-cv8-newmm - Thai Wav2Vec2 with CommonVoice V8 (newmm tokenizer) + language model
• wannaphong/wav2vec2-large-xlsr-53-th-cv8-deepcut - Thai Wav2Vec2 with CommonVoice V8 (deepcut tokenizer) + language model
