Emulating Human Voice-overs with TTS Voices, Part Three
By Rudy Helm, Audio and Quality Assurance Tech, Visual Purple, LLC.
Continuing with our vlog ‘how-to’ series called, ‘Emulating Human Voice-overs with TTS Voices’ we now offer this newer presentation, suffixed as ‘Part Three’. We recommend that you review Part One and Part Two first but that is not necessarily a requirement. For this exercise we snipped out a small piece from one of our past projects. Unlike the premise of Part 2, where you learned to sync a TTS voice to a human voice-actor, this video tutorial will focus on the tactics of humanizing synthetic voice-clips with added detail. Today’s presentation does not only reinforce the techniques discussed in Part 1 and Part 2, but will show how to set the talk-pace to improve the phrasings and expressions of synthetic voices. And the concept of formant manipulation is introduced as well. Disclaimer: these are helpful tips, but generalized. Not all editing tools or TTS engines respond to specific techniques that you might try in the very same way. Mainly, just try to grasp the concepts, then adapt your technique to idiosyncrasies of your chosen tools.
