Apple Reveals "Hey, Siri" Feature Relating to Future Apps for Restaurant Reservations, In-Vehicle Functionality and more

In December 2013 the US Patent & Trademark Office published a patent application from Apple that revealed a new restaurant ordering and reservation system that could work with various Apple iDevices. It covered "Managing a Wait List; an Exemplary Ordering System; and an Exemplary Notification System." Today the US Patent and Trademark Office reveals a new patent application from Apple that introduces an energy-efficient voice trigger that can be used to initiate voice- and/or speech-based services on a device via Siri; a low-powered voice trigger that can provide "always-listening" voice trigger functionality without excessively consuming limited power resources. One of the examples used by Apple relates back to the restaurant reservation system introduced in December.


Apple Invents a Voice Trigger for a Digital Assistant


A Restaurant Reservation Example


In Apple's patent FIG. 3 presented below we're able to see the ontology (#360) relating to a "restaurant reservation" node, which is an actionable intent node. Property nodes "restaurant," "date/time" (for the reservation), and "party size" are each directly linked to the "restaurant reservation" node (i.e., the actionable intent node). In addition, property nodes "cuisine," "price range," "phone number," and "location" are sub-nodes of the property node "restaurant," and are each linked to the "restaurant reservation" node (i.e., the actionable intent node) through the intermediate property node "restaurant."


For another example, the ontology shown in FIG. 3C also includes a "set reminder" node, which is another actionable intent node. Property nodes "date/time" (for the setting the reminder) and "subject" (for the reminder) are each linked to the "set reminder" node. Since the property "date/time" is relevant to both the task of making a restaurant reservation and the task of setting a reminder, the property node "date/time" is linked to both the "restaurant reservation" node and the "set reminder" node in the ontology.    



An In-Vehicle Example


Apple later notes in their patent filing that the device can detect whether it is in a vehicle (e.g., a car). A voice trigger is particularly beneficial for invoking a speech-based service when the user is in a vehicle, as it helps reduce the physical interactions that are necessary to operate the device and/or the speech based service. Indeed, one of the benefits of a voice-based digital assistant is that it can be used to perform tasks where looking at and touching a device would be impractical or unsafe. Thus, the voice trigger may be used when the device is in a vehicle so that the user does not have to touch the device in order to invoke the digitalassistant.


Apple introduces: Hey, Siri



Apple's latest patent filing relates to a feature that Craig Federighi introduced in June at their World Wide Developer Conference in San Francisco.


In Apple's patent summary they note that their invention relates to systems and methods for initiating a voice-based assistant using a voice trigger at an electronic device. Interactions with a voice-based digital assistant (or other speech-based services, such as a speech-to-text transcription service) often begin when a user presses an affordance (e.g., a button or icon) on a device in order to activate the digital assistant, followed by the device providing some indication to the user that the digital assistant is active and listening, such as a light, a sound (e.g., a beep), or a vocalized output (e.g., "what can I do for you?").


The voice triggers can also be implemented so that they are activated in response to a specific, predetermined word, phrase, or sound, and without requiring a physical interaction by the user. For example, a user may be able to activate a SIRI digital assistant on an iPhone by reciting the phrase "Hey, SIRI."


In response, the device outputs a beep, sound, or speech output (e.g., "what can I do for you?") indicating to the user that the listening mode is active. Accordingly, the user can initiate an interaction with the digital assistant without having to physically touch the device that provides the digital assistant functionality.
