Prosody is not something used by alien abductors. It’s defined in Merriam Webster as ‘the rhythm and pattern of sounds of poetry and language.’ The lack of it makes C-SPAN boring and Ben Stein funny. Basically, it’s music in the way you talk. On that note (badum-tish), some of the training exercises from music also apply to voiceovers. If you’ve had singing lessons before, you may be familiar with the warm-ups before performances. Warming up helps to extend the amount of time you can speak without strain, and to push your voice to higher and lower notes. (Handy for the next time you’re screaming while your avatar runs from an unfriendly rock troll.) There are a lot of voice instructors on YouTube (I mentioned Song Bird Tree in an earlier post about tea), with plenty of instructional videos and styles of teaching from upbeat to relaxed. A word of caution, though - do you know your range? Actual musicians who know more than I do have placed me in the alto section of choirs since before high school, so I’m comfortable with their assessment, and use corresponding exercises. If you warm-up with, say, a tenor exercise when you’re a baritone, your throat may end up feeling like you just got out of a concert with that hot redhead drummer, you know the one, long hair and a big drumset? I digress. There’s at least one video that gives you a ‘quick and dirty’ way to figure out your range, but consider getting a second opinion from a more experienced ear - another reason to seek out a voice instructor.
