Google recently upgraded the voice of Google Now to make it sound a bit less robotic and results are certainly noticeable. But we wanted to know, of the top three personal assistants, which one sounds the best?

Despite efforts to make them sound human, Google Now, Siri and Cortana's voices still hint at the robots they truly are. They aren't like Jarvis, at least not yet.

Tone, cadence, delivery and attitude all affect each assistant's vocal style. While Google Now sounds less robotic in tone, Cortana clearly nails comedic timing and Siri has a bit more attitude. Check out the video above where we put them through their paces and deem one the most human and entertaining of them all.
