任何人都可以帮我解决问题。
使用转发器控件从数据库加载数据。它正常工作，虽然我正在为视障人士使用，但我正在使用SpeechSynthesizer为用户提供音频输出。

//need more itemindex to be looped; because having 100 of records to be accessed.
}
}

我尝试了什么：
如果不使用转发器，音频工作正常，但我需要将100个数据加载到页面，所以我一定要转发。使用转发器，SpeechSynthesizer无法正常工作。请检查我的代码并做必要的事情。
What I have tried:
Without using repeater the audio is working perfectly , but I need to load 100’s of data to the page, so I bound to repeater. Using repeater the SpeechSynthesizer is not functioning. Please check my code and do the needful.
