Text and Voice “Tone” Analysis
Siri’s intelligence and capabilities have long been a significant reason why HomePod has fallen behind other competitors. While the patent doesn’t necessarily go into detail about potential Siri upgrades, it does hint at some added capabilities that could come to the digital assistant.
At one point, the patent describes how Siri could analyze a user’s voice and determine their mood or emotion. On the flip side, another portion of the patent details how Siri may be able to analyze the “tone” of an email and read it back to users while displaying an appropriate visual LED indicator (email senders could even pick which emotion they’d like Siri to display).
