1. A method implemented by one or more processors, the method comprising:
processing audio data received by a computing device that provides access to an automated assistant,
wherein the audio data is processed in furtherance of determining whether a user provided an invocation phrase to the automated assistant;
causing, in response to receiving the audio data, a radar device of the computing device to provide a transmission to an environment of the computing device,
wherein the transmission is provided in furtherance of determining whether the user is present in the environment;
processing radar data that indicates one or more differences between the transmission provided to the environment and reflected data that is generated in response to the transmission being provided to the environment,
wherein the one or more differences indicate whether the user is present in the environment;
determining, based on the radar data and the audio data, whether to modify a setting of an input detection feature of the automated assistant,
wherein the setting controls a confidence threshold for responding to one or more subsequent spoken utterances received from the user within a duration of time of the automated assistant receiving the invocation phrase from the user; and
when the setting of the input detection feature of the automated assistant is modified based on the radar data and the audio data:
causing additional audio data to be processed, according to the setting, in furtherance of determining whether the user provided a subsequent spoken utterance that embodies a request for the automated assistant.
