AI Technical Summary

Problems solved by technology

However, speech-to-text processing is computationally intensive and consumes significant processing power and reduces battery life in handheld devices
Furthermore, voice recognition is prone to noise and errors, resulting in a lower recognition accuracy, which further leads to failure to wake up the voice assistant when it needs to be woken up, or accidentally waking up the assistant when the user does not need to wake up the assistant

Embodiment Construction

[0022] Embodiments described below provide systems and methods for activating voice-based assistants in electronic devices using voice triggers. Interaction with a voice-based digital assistant (or other voice-based services, such as a speech-to-text transcription service) typically begins when the user presses an affordance (e.g., a button or icon) on the device to activate a digital When the assistant is installed, the device then provides the user with some indication that the digital assistant is active and listening, such as a light, sound (e.g., beep), or audible output (e.g., "How can I help you?"). As described herein, voice triggers may also be implemented such that they are activated in response to a particular predetermined word, phrase or sound and do not require physical interaction by the user. For example, a user can activate a voice assistant by reciting a pre-defined trigger phrase "Hi, Assistant!" In response, the device outputs a beep, sound, or voice outpu...

Abstract

A method for controlling a home assistant device includes: receiving an audio input (502); performing speaker recognition on the audio input (504); in accordance with a determination that the audio input includes a voice input from a first user that is authorized to control the home assistant device: performing speech-to-text conversion on the audio input to obtain a textual string (506); and searching for a predefined trigger word for activating the home assistant device in the textual string; and in accordance with a determination that the audio input includes a voice input from the home assistant device: forgoing performance of speech-to-text conversion on the audio input; and forgoing search for the predefined trigger word (508).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application No. 62 / 612,551 filed December 30, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to digital assistants, and more particularly, to a method and system for controlling digital assistants using voice-based commands. Background technique [0004] Recently, voice-based digital assistants, such as Apple's SIRI (Apple Intelligent Voice Assistant), Amazon's Echo (Amazon Smart Speaker), Google's Google Assistant (Google Assistant), and Microsoft's Cortana (Microsoft Cortana), have been introduced into market to handle a wide variety of tasks, such as home appliance control, web search, scheduling, reminders, and more. The advantage of such a voice-based digital assistant is that the user can interact with the device in a hands-free manner without touching or even looking...
