Alexa now uses transfer learning and self-learning to improve on its own…
TL: deep-learning to model many domains and transfer the knowledge from one to the next
SL: autocorrecting based on context clues
And in October 2018, Amazon patented a new technology for Alexa to monitor emotions through the pitch and volume of speech. The patent says that Alexa may be able to identify “happiness, joy, anger, sorrow, sadness, fear, disgust, boredom, stress” and then respond with “highly targeted audio content”.
According to the Atlantic, Google has something similar, with a patent “providing help information based on emotion detection”. And IBM is working on “web search based on browsing history and emotional state”.
Gulp.
