Few minutes after publishing the post on Albert Mehrabian studies and the often misinterpreted 7%-38%-53% rule, I received a newsletter (from VoxGig) containing this TEDxTalk about Voice Branding, and I thought that it really complements the previous post.
Content doesn’t count for 7% only, but your voice is still an important part of the overall presentation, especially for virtual sessions.
After looking at the video, there are many other presentations on TED about voice and sessions. You can work on your voice and obtain more results!
