My work paid for our department to work with professional speaking consultants, who taught us everything. It was a bit mortifying at first, especially the media training with the camera and lights, but got easier.
Going forward, I would always set aside money in my dept budget for ongoing team and 1x1 training.
Some people have used Toastmasters. And there are APPS!! I’ve cut and pasted a list below:
VirtualSpeech: This app provides photo-realistic environments to train in, including realistic audiences and environments, sound distractions, voice analysis, and interactive courses. It is available on mobile and VR headsets.

Preply: This app offers practice exercises, personalized tips, and speech coaching. It allows users to record and analyze their speeches and share their recordings with others for additional feedback and critique.
