We have created highlight feature, i.e., the sentence will get highlighted when the audio is played, by used HTML5 audio. On click of each sentence, the audio should readout from particular duration. Example: if the sentence is started in 22.5 ms - 31.8. The audio should play only the duration set. This works in other browsers. But in firefox, the audio and the text is not syncing and highlighting. Is there any fix for this problem.
