AndrewMcDowell/wav2vec2-xls-r-300m-japanese

This model is a fine-tuned version of facebook/wav2vec2-xls-r-300m on the MOZILLA-FOUNDATION/COMMON_VOICE_8_0 - JA dataset.

Kanji are converted into Hiragana using the pykakasi library during training and evaluation. The model can output both Hiragana and Katakana characters. Since there is no spacing, WER is not a suitable metric for evaluating performance and CER is more suitable.

On mozilla-foundation/common_voice_8_0 it achieved:

• cer: 23.64%

On speech-recognition-community-v2/dev_data it achieved:

• cer: 30.99%

It achieves the following results on the evaluation set:

• Loss: 0.5212
• Wer: 1.3068
