Know that even in all party consent states, if you continue talking after being made aware that the conversation is being recorded implies consent. This is why devices like google home are legal, they make a loud warning sound before they begin recording. For example in CA the law states that:
> (a) A person who, intentionally and without the consent of all parties to a confidential communication, uses an electronic amplifying or recording device to eavesdrop upon or record the confidential communication, whether the communication is carried on among the parties in the presence of one another or by means of a telegraph, telephone, or other device, except a radio, shall be punished...
(b) For the purposes of this section, “person” means an individual, business association, partnership, corporation, limited liability company, or other legal entity, and an individual acting or purporting to act for or on behalf of any government or subdivision thereof, whether federal, state, or local, but excludes an individual known by all parties to a confidential communication to be overhearing or recording the communication.
> they make a loud warning sound before they begin recording
This contradicts my personal experience last week with a google-controlled music player. Music was the only response to a voice command to play music, and silence was the only response to a voice command to turn it off.
> (a) A person who, intentionally and without the consent of all parties to a confidential communication, uses an electronic amplifying or recording device to eavesdrop upon or record the confidential communication, whether the communication is carried on among the parties in the presence of one another or by means of a telegraph, telephone, or other device, except a radio, shall be punished...
