Abstract: System and method for controlling a home assistant device include: receiving an audio input; performing speech-to-text conversion on the audio input to obtain a textual string; searching a name list of multiple home devices to determine whether the textual string includes a respective alias of at least one home device in the name list; in accordance with a determination that the textual string includes a first alias corresponding to a first home device of a first device type, generating a first actionable intent to operate the first home device of the first device type; and in accordance with a determination that the textual string includes a second alias corresponding to a second home device of the first device type that is distinct from the first home device, generating a second actionable intent to operate the second home device of the first device type.

Abstract: System and method for controlling a home assistant device include: receiving an audio input; performing speaker recognition on the audio input; 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; 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.

Abstract: A method for generating context-free grammar for intent deduction includes: retrieving, through a compiler, a first template file for a respective actionable intent corresponding to a first task that is to be performed by a machine; parsing the first template file, using the compiler, to identify a first nonterminal variable that refers to a first nonterminal file containing a plurality of first named entity values; and generating, based on a plurality of production rules specified in the first template file, including at least a first production rule that includes the first nonterminal variable, first context-free grammar for the respective actionable intent corresponding to the first task, wherein generating the first context-free grammar for the respective actionable intent corresponding to the first task includes rewriting the first production rule by replacing the first nonterminal variable in the first production rule with the plurality of first named entity values.
