Text to speech sounds off on iMac but works on macbook?

Hi all! I have a bit of a issue that I so far have no work around for. 

I’ve been using scrivener (a writing app) for a few years now. I use to write on just my laptop (MacBook Pro 2020, operation off the newest sequoia) but I recently got a IMac 2017 (operating off of the newest Ventura) from my partner for writing. I was super excited to use it, but one of the main functions I use (Speech) is unusable. I can use the Siri special voices (I like using voice 4 or 5 for reference) but when I play back what I’ve written, the speech is robotic and glitchy. On my laptop I don’t have this issue at all. When I play the sample within accessibility, the voice sounds completely normal. I checked and yes, the voice files are both 400 ish MB. 

I have tried listening to the speech on different applications (through notes, safari, chrome, anything) and it is still robotic. I have done all the trouble shooting. I have restarted my iMac, I have messed around with the Auto MIDI settings (and then reset them when nothing worked) I have checked the Input and output in Sound, changed the voices in the Accessibility setting to see if it was just that specific voice. Redownloaded the voice. I even looked into coding. I cleared my cache, seen if my iMac is on low battery mode. ANYTHING. Nothing is working. When the voice reads, she even skips over words at times or doesn’t pronounce it correctly (eyes becomes y-es). I use the system default language, and tried changing it to English with no luck. I found a forum talking about changing the actual plist file by going to finder>go>hold command>library>preferences>find the file names com.speech.voice. Blah blah blah and change that to _old and then go from there and NOTHING. Someone please help, or at least tell me if this is just a normal issue. I have no idea why my macbook reads my speech so clearly compared to my imac.
