Microphone making me sound robotic on Teams / Zoom calls

i have been told I sound robotic on company Teams & Zoom calls. This has only happened in the last update of Mac OS. Has anyone else come across this and found a solution?

Mac OS: Version 14.4 Beta (23E5196e) Mac: Mac Ultra M1 / 64Gb Mem / 1TB SSD

Again only happened since last update last week....
