Yep. Each of our TTS models is based on a real actor's voice that has its own nuanced characteristics. Some voices are naturally rougher / croaky while others smooth. As in real life, our differences are what make us unique. Some voices will work better for certain character profiles / scenes - it's up to the user to decide.

Yeah, but wouldn't you include at least one "clean" voice in the samples to show what the system is capable of?
