Model Card for Model ID

This is the baseline model of Khummuang in Thai-dialect corpus.

The training recipe was based on wsj recipe in espnet.

Model Description

This model is a Hybrid CTC/Attention model with pre-trained HuBERT encoder.

The model was pre-trained on Thai-central, Khummuang, Korat, and Pattani and fine-tuned on Khummuang, Korat, and Pattani. (Experiment 3 in the paper)

We provide some demo code to do inference with this model architecture on colab here. (Code is for Thai-Central. Please select the correct model accordingly.)

Evaluation

For evaluation, the metrics are CER and WER. before WER evaluation, transcriptions were re-tokenized using newmm tokenizer in PyThaiNLP

In this reposirity, we also provide the vocabulary for building the newmm tokenizer using this script:

python

from pythainlp import Tokenizer

def get_tokenizer(vocab):

    custom_vocab = set(vocab)
    custom_tokenizer = Tokenizer(custom_vocab, engine='newmm')
    return custom_tokenizer

with open(<vocab_path>,'r',encoding='utf-8') as f:
        vocab = []
        for line in f.readlines():
            vocab.append(line.strip())

custom_tokenizer = get_tokenizer(vocab)

tokenized_sentence_list = custom_tokenizer.word_tokenize(<your_sentence>)

The CER and WER results on test set are:

Micro CER	Macro CER	Survival CER	E-commerce WER	Micro WER	Macro WER	Survival WER	E-commerce WER
5.35	5.65	6.29	5.02	7.53	8.73	11.38	6.09
