Google patents using phone odor sensors to identify smells and alert users

1. A method implemented by one or more processors, the method comprising: at a plurality of time instances: obtaining corresponding odor data instances generated by an odor sensor of a client device of a user; processing the corresponding odor data instances to generate corresponding outputs for the corresponding odor data instances; and identifying, based on the corresponding outputs, one or more baseline odors associated with a physical environment of the client device; and at a subsequent time instance that is subsequent to each of the plurality of time instances: obtaining a given odor data instance generated by the odor sensor of the client device of the user or an additional odor sensor of an additional client device of the user that is co-located in the physical environment of the client device; processing the given odor data instance to generate given output for the given odor data instance; identifying, based on the given output, a given odor in the physical environment of the client device; determining that the given odor in the physical environment of the client device does not correspond to one or more of the baseline odors associated with the physical environment of the client device; and in response to determining that the given odor in the physical environment of the client device that does not correspond to one or more of the baseline odors associated with the physical environment of the client device: generating synthesized speech audio data that captures synthesized speech identifying the given odor in the physical environment of the client device; and causing the synthesized speech audio data that captures the synthesized speech identifying the given odor in the physical environment of the client device to be rendered for audible presentation to the user via one or more speakers of the client device or the additional client device of the user.
