A human computer interaction system, comprising: at least one user input interface; at least one output interface; an automated device; and a control system operatively connected to the at least one user input interface, the at least one output interface, and the automated device, the control system being configured to: receive a series of spoken inputs from a user with the at least one input interface; identify the user using a continuous authentication process with a privacy and security management module in the control system; predict a level of authority for the user within a hierarchy of a plurality of users of the system; operate the automated device based on a command from the user in the series of spoken inputs only in response to the level of authority for the user being great enough to authorize the operation of the automated device; characterized in that the control system being further configured to: identify the user as a child in a family hierarchy; generate a request message specifying the command from the child for a parent in the family hierarchy with the at least one output interface; receive a spoken response to the request message from another user; identify the other user as the parent using the continuous authentication process with the privacy and security management module; and operate the automated device based on the command from the child only in response to the spoken response from the parent approving the requested command. at least one user input interface; at least one output interface; an automated device; and a control system operatively connected to the at least one user input interface, the at least one output interface, and the automated device, the control system being configured to: receive a series of spoken inputs from a user with the at least one input interface; identify the user using a continuous authentication process with a privacy and security management module in the control system; predict a level of authority for the user within a hierarchy of a plurality of users of the system; operate the automated device based on a command from the user in the series of spoken inputs only in response to the level of authority for the user being great enough to authorize the operation of the automated device; characterized in that the control system being further configured to: identify the user as a child in a family hierarchy; generate a request message specifying the command from the child for a parent in the family hierarchy with the at least one output interface; receive a spoken response to the request message from another user; identify the other user as the parent using the continuous authentication process with the privacy and security management module; and operate the automated device based on the command from the child only in response to the spoken response from the parent approving the requested command. receive a series of spoken inputs from a user with the at least one input interface; identify the user using a continuous authentication process with a privacy and security management module in the control system; predict a level of authority for the user within a hierarchy of a plurality of users of the system; operate the automated device based on a command from the user in the series of spoken inputs only in response to the level of authority for the user being great enough to authorize the operation of the automated device; characterized in that the control system being further configured to: identify the user as a child in a family hierarchy; generate a request message specifying the command from the child for a parent in the family hierarchy with the at least one output interface; receive a spoken response to the request message from another user; identify the other user as the parent using the continuous authentication process with the privacy and security management module; and operate the automated device based on the command from the child only in response to the spoken response from the parent approving the requested command. identify the user as a child in a family hierarchy; generate a request message specifying the command from the child for a parent in the family hierarchy with the at least one output interface; receive a spoken response to the request message from another user; identify the other user as the parent using the continuous authentication process with the privacy and security management module; and operate the automated device based on the command from the child only in response to the spoken response from the parent approving the requested command.
