1. A method of operating an electronic device configured to be responsive to any of a plurality of affordances, the plurality of affordances including: (i) an audio-based affordance comprising a hotword, and (ii) a non-audio-based affordance, the method comprising:
determining a noise profile of an environment associated with the electronic device;
prior to detecting the audio-based affordance, determining that the noise profile of the environment exceeds a volume level threshold that would interfere with recognition of the hotword of the audio-based affordance, wherein the volume level threshold is defined based on a predefined distance from the electronic device; and
based on determining that the noise profile of the environment would interfere with recognition of the hotword, presenting an indication to use the non-audio-based affordance instead of the audio-based affordance to awaken the electronic device.
