Siri vs Cortana vs Google Now vs Plexi : Voice Assistant Shoot out

647 views 1 day ago

This is a test of just over 20 questions comparing information retrieval features of Siri, Microsoft Cortana, Google Now, and Plexi. ( http://www.windowsphone.com... )

Cortana just was released to developers as part of the Windows Phone 8.1 update and we wanted to see how she stacked up to the competition. Each question was asked the same way to each assistant. We re-tried if voice recognition was an issue so that they would be tested on their ability to answer questions rather than the pronunciation of the user.

Yes, my product one. But Siri did nearly as well. Plexi will do more of the "call", "text", and "calendar" stuff soon, but Windows Phone API's tend to be a bit protective of privacy and so we didn't optimize for those tasks. Think of this as a review of how Natural Language Processing can help with your homework.

It is worth noting Plexi doesn't use Wolfram Alpha, and only uses Wikipedia for abstracts on certain topics.

Plexi believes it is a failure if we have to drop the user to a search result when they didn't ask for search.
