Is there some rule for when one should pronounce 'te' as 'ta' in a song?


At [0:37 in the OP of the anime Gotoubun no
Hanayome](https://youtu.be/tF04aIba5p8?t=33), Miku pronounces her lyrics
'kizuite' as 'kizuita'. I wonder if there's some singing rule for when this
should be done.




I agree with aguijonazo. I don't have expertise in phonetics, but now that you
mention it, it does sound like something in between て and た to my ears (as a
native speaker). However, there is no rule that says one should pronounce it
this way in a song. It just happened to sound like that as she was trying to
sing it in a cute way.
