I have time-coded a video using Aegisub, so each line contains a meaningful sentence. Now I want to use some tool to generate text (doesn't matter if it's imperfect) for each line.

I tried using google docs text-to-speech utility. But I'll have to play the whole video without respect to timecodes, potplayer allows you to jump into next/previous subtitle position, but once you hit play, it'll play until the end of the video and can't be set to the end of subtitles. Any help please?
