Results are in. But the WER is inflated by Whisper converting spelled-out numbers to digits (e.g., "two hundred and fifty" → "250"). Also Chinese WER is 100% because Whisper outputs traditional characters. Let me fix the evaluation to normalize these properly for a fair accuracy assessment.

The results are actually quite telling. Let me analyze what happened:

1. **Pure text accuracy** (no numbers/special formatting): The model achieves **0% WER** on clean English, Japanese, and Korean sentences. That's perfect.

2. **Number formatting mismatch**: Whisper transcribes spoken numbers as digits ("250" vs "two hundred and fifty"), which inflates WER. This isn't a TTS error - the model correctly spoke the numbers.

3. **Chinese traditional vs simplified**: Whisper outputs traditional Chinese characters, inflating CER. Again, the speech was correct.

4. **Punctuation differences**: Whisper doesn't always transcribe quotes/punctuation exactly.

I need to add text normalization to the evaluation—handling number conversion, character simplification, and punctuation standardization—so I can show both the raw scores and the normalized ones for a more accurate comparison.

Updating the evaluation script...


The raw numbers are misleading - the high WER is mostly Whisper formatting differences (numbers as digits, traditional vs simplified Chinese), not actual TTS errors. Let me add proper text normalization for a fair accuracy measure.
