[LS] Gallery Sims from Cupid's Corner have high-pitched voices

Thank you. 

And here I thought my sim was having either an existential crisis cause she is preggers from another sim and now is dating basically the sim of her life ( because their connection is way better then with the sim that is the father of her child)  or was hormonal and having a troubled hearing :P 

My sim was asked on a date (her first with this sim) and the sim male she met via cupids corner and he is indeed a gallery created sim. 
I first thought he had no voice (since it seems the sound is out of sync with the sims actions itself) and I was listening to a female sim nearby the couple that happened to be chattering, but then I realised it was indeed the male sim.

So, yes the bug is still present in the game (to answer those that have asked if it still exists.)
And knowing it is not the mods saves me digging out the mods to see which one it is. Thank you for delivering that info!!

I shall patiently wait for the answer to solve this.

I have the same issue in my game. I'm playing The Sims 4 right now. I just had a date with a sim that my sim knows from Cupid's Corner. Her date is a male sim created by someone on the gallery, so this sim was imported in my game. This date was the first time they met. He had a female voice. I used the CAS.fulleditmode cheat to see if I could change his voice, but I had the same issue as you. In CAS his voice was set to a male voice. I also changed some outfits and when I loaded back into live mode, the voice nor outfits were changed... Very strange... Hopefully they can fix this issue, because it is quite annoying.

I have the same issue. all males on dates have female voices and that makes me not want to use cupid corner at all.

I am really tired of picking cute men from the Gallery on Cupid’s Corner, only to have them sound like girls!! You can put them in CAS or on a home lot and hear their intended voice, but when out and about, they revert to using women’s voices. It’s weird and off putting!!
