If you work in radio or voiceover you learn really quickly that the voice is so much more complex than people give it credit for. Subtle changes in delivery, timing, inflection, syllabic emphasis, pauses etc... make a massive difference.

Anyone can "talk like a robot" but speaking naturally is way more dynamical than just making the sounds of the words transition smoothly.

I'm not sure if it's way easier or way harder than we're doing it now.
