Api.ai makes an Android voice-controlled utility called
Assistant. I have it on my Android phone. It is
one of many simiar apps, and I have been trying them a little at a time. Are any of them as good as Siri? Let's just say, "Quality varies."
And Android voice assistants aren't the point of this interview, anyway. It's more about the process of developing interactive, voice-based IO systems. This whole voice/response thing is an area that's going to take off any year now -- and has been in that state for several decades -- but may finally be going somewhere, spurred by intense competition between the many companies working in this field, including Ilya's.
