This is fine
It’s almost as if the manufacturers of smart speakers want everyone to get used to accidental activations:
Voice assistants in smart speakers analyze every sound in their environment for their wake word, e.g., «Alexa» or «Hey Siri», before uploading the audio stream to the cloud. This supports users’ privacy by only capturing the necessary audio and not recording anything else. The sensitivity of the wake word detection tries to strike a balance between data protection and technical optimization, but can be tricked using similar words or sounds that result in an accidental trigger.
