Greetings.
I ask you to indicate where to dig. I am making a mobile app. I have in my hands the text of several fairy tales in text format and several mp3 files in which the announcer reads these very tales. I need to somehow make sure that the text is not just displayed gradually, it is simple. I need to make it so that:

  1. the voice and text were somehow synchronized
  2. Because of paragraph 1) it will be possible to select a specific playback location without very long dances with a tambourine using swipe. (It sounds incomprehensible. Instead of the classic playback slider, they say I want to switch to 1:37 from 2:20 and back, I need to do swipe control, that is, swipe up - rewind the tale a little forward, swipe down - rewind the tale a little back. I hope clearly explained.) How can something like this be realized, so much so that both a piece of the speaker’s voice and the text itself move to the right place? Thank you in advance.

Hi,

Sounds like you are outsourcing your work to here… Why not try Unity connect instead?

Here’s some generic advice: Split your problem to parts and solve each part one by one. It’s best probably to prioritize your work and evaluate which things are critical to get your prototype working. Then you can use some project methodology like critical path to schedule your activities so that you get your app done.

You can probably find some services out there that do audio sync, either automatically using software, or done by humans. This will most likely cost you some money. Or do it yourself.
