Siri, artificial intelligence, and accessibility

The magic and frustration of voice assistants and artificial intelligence when it comes to accessibility. A lot has been said recently about Apple's prospects in artificial intelligence and machine learning. One aspect of the discussion that I haven't seen considered is the accessibility ramifications of artificial intelligence in assistants like Siri. I've long been a proponent of voice-driven interfaces as assistive technology, which makes Siri's slow development all the more frustrating. This is particularly true when it comes to Siri understanding you if you have trouble speaking.
