Summary

The Word Error Rate (WER) of 26.23% is respectable, indicating that roughly three out of every four words are transcribed correctly. While there is room for improvement, this is a functional level of accuracy.

The model excels at the character level, with a low Character Error Rate (CER) of 8.80% and a very high ChrF score of 81.64. This shows it accurately captures the phonetic and structural details of the language. The high BLEU score further confirms that the generated transcriptions are coherent and closely match the reference text.

In summary, this is a high-performing and reliable ASR system that produces largely accurate and intelligible transcriptions.
