Before there was Alexa, there was ALisA. Well, both were in stealth development simultaneously.
In many ways this project is similar to Alexa, but it was also very different and had a roadmap for HUI features that are not yet available in any voice activated AI assistant. ALisA was conceived as a subscription SaaS application. She was designed to run on home based machines such as a laptop, desktop, or dedicated device. She had a very user-centric commitment in that usage and data would always be strictly private and never monetized.
AlisA can be considered my baby since my role included market analysis, business modeling, concept development, technology research, app functionality design, voice interface design, and dialog design. In the process I constructed a fault management logic that enabled ALisA to know at what point she was lacking knowledge (data) and how to deal with it. (Thus the blurred responses in the dialog diagram.)
The scale of such a project is massive, particularly where AI meets multi-interaction modes and with the advent of competitive products from major technology companies, a decision to halt development was made. Still, those competitors have (so far) fallen short of ALisA's roadmap and absolutely do not have the very crucial intelligent fault management system.
