哪个html5 网页音乐播放器能指定单句重复次数呢？
本帖最后由 blackantt 于 2024-3-20 18:28 编辑AI写的(https://fishc.com.cn/thread-241179-1-1.html)老是不对。
1. 能改改将就实现: 从1.mp3，1.srt 或者 1.lrc读句子，然后用按钮指定每句读 3 次，再跳到下一句，读3次。直至mp3播放完吗。
2.或者github 上有这种现成的html5 网页播放器吗？(这里有一个，就是不能按句复读，供参考，https://imajineweb.com/javascriptaudioplayer/)
下面这个是 Gemini 写的，还是不行
