in a previous video, I showed the results of this but not the process.

The reason it's recorded on my phone was because it was much easier to edit on my phone.

I accidentally left stuff out. For the modify duration script, you need a Textgrid that is identical to the original UST and one that is fitted to the audio you had sung. You open the Praat scripts in Praat the same way you open audio or textgrids. And plenty more things I forgot to mention!!

The farther away from 120 BPM you stray, the weirder the pitch curve looks. No idea how to fix it! but at 105 it looked nasty but still played fine.

if you really, really care about clarity, you can edit the part of the script that creates the dynamics curve so there is more dynamic range. just make sure if you multiply the intensity by a higher number, subtract a higher number

You can test out the UST here:

The modify duration script was edited from scripts made by @hataori301 You can see the original scripts with the original instructions here:

Here are all of the web pages and scripts:
