<!-- Provide a quick summary of what the model is/does. -->
|
14 |
+
|
15 |
+
This is the baseline model of Thai-central in [Thai-dialect corpus](https://github.com/SLSCU/thai-dialect-corpus).
|
16 |
+
|
17 |
+
The training recipe was based on wsj recipe in [espnet](https://github.com/espnet/espnet/).

### Model Description
|
22 |
+
|
23 |
+
<!-- Provide a longer summary of what this model is. -->
|
24 |
+
|
25 |
+
This model is Hybrid CTC/Attention model with pre-trained HuBERT as the encoder.
|
26 |
+
|
27 |
+
This model trained on Thai-central for being the supervised pre-trained model in transfer-based curriculum learning experiment.
|
28 |

+
you can demo on colab with [this link](https://colab.research.google.com/drive/1stltGdpG9OV-sCl9QgkvEXZV7fGB2Ixe?usp=sharing). (Free google colab cannot inferences > 3 seconds of speech.)

## Evaluation
|
33 |
+
|
34 |
+
<!-- This section describes the evaluation protocols and provides the results. -->
|
35 |
+
|
36 |
+
For evaluation, the metrics are CER and WER. before WER evaluation, transcriptions were re-tokenized using newmm tokenizer in [PyThaiNLP](https://github.com/PyThaiNLP/pythainlp)
|
37 |
+
|
38 |
+
In this reposirity, we also provide the vocabulary for building the newmm tokenizer using this script:
|
39 |
+
|
40 |
+
```python
|
41 |
+
from pythainlp import word_tokenize
|
42 |
+
|
43 |
+
tokenized_sentence_list = word_tokenize(<your_sentence>)
|
44 |
+
```
|
45 |
+
|
46 |
+
CER = 2.0
|
47 |
+
WER = 6.9
