Thanks! We looked into randomising between a couple voices a while ago. To my surprise, we found that all the voice models on our text-to-speech service (Microsoft Azure) perform somewhat differently. This means our quality assurance costs would go up quite a lot if we start using several voices.
I’d also guess that once listeners become familiar with a particular voice, their comprehension improves and they’re able to listen faster. I have some anecdotal evidence of this, but I’m pretty unsure how big of a deal it is.
