Youdao Speech API Returns 500 Error for Phrases Containing Special Characters

[zhouzhongyuan]

Thank you very much for the great tool. I found an issue when fetching speech audio using the Youdao dictvoice API.

How to reproduce this problem?

1. Take "雅思wang C5" -> first chapter -> first word as exmaple.
   The vocabulary item is

a (great) variety of 

2. The API to fetch speech is

https://dict.youdao.com/dictvoice?audio=a%20(great)%20variety%20of&type=2

3. When calling this URL, Youdao’s API returns an error page:

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

4. This issue happens for many other words/phrases that include special characters such as parentheses, punctuation, etc.

Suggestion

Would it be possible for qwerty to switch to a more robust TTS service?
For example: Edge-TTS is stable, supports phrases, and handles special characters much better.
