Cer Runtime: 0.1534

Model description

This is an open-source Traditional Chinese (Taiwan) automatic speech recognition (ASR) model.

Intended uses & limitations

This model is designed to be a prompt-free ASR model for Traditional Chinese. Due to its inherited language identification (LID) system from Whisper, which supports other Chinese language variants under the same language token (zh), we expect that performance may degrade when transcribing Simplified Chinese.

The model is free to use under the MIT license.

Training and evaluation data

This model was trained on the Common Voice Corpus 19.0 Chinese (Taiwan) Subset, containing about 50k training examples (44 hours) and 5k test examples (5 hours). This dataset is four times larger than the combination of training and validation set (train+validation) of mozilla-foundation/common_voice_16_1, which includes about 12k examples.
