 ### Issue Encountered & Solution
 
-I encountered the issue that the inconsistent volume levels across different recording sessions, which could hinder the TTS model's performance. To resolve this, I used Audacity’s "Normalize" to solve it.
+I encountered the issue that the inconsistent volume levels across different recording sessions, which could hinder the TTS model's performance. To resolve this, I used Audacity’s "Normalize" to solve it. And the original script contained several Arabic numerals and English acronyms (e.g., "1938"). Directly using these in the rom column would lead to unpredictable phonetic outputs. I resolved this by "normalizing" the text—converting all numbers into full Chinese characters (e.g., "一九三八") in the metadata to ensure the model learns the exact pronunciation intended.
