1. An apparatus for natural machine conversing with a user, comprising:

  • listening circuitry, including a first autonomous speech recognition (ASR) engine, to detect a keyword that denotes start of a conversation between the apparatus and the user;

    dialogue circuitry, including a second ASR engine with greater speech recognition capability than the first ASR engine, to converse with the user during the conversation, including to detect for one or more conversation continuing features during the conversation, the one or more conversation continuing features include at least selected pitch attributes of the user; and

    a controller coupled to the listening circuitry and the dialogue circuitry to selectively activate or cause to be activated one of the listening circuitry or the dialogue circuitry, and to pass control to the activated listening circuitry or the activated dialogue circuitry, based at least in part on a current state of the conversation, which includes at least a start state, a continuing state, and an end state;

    wherein the dialogue circuitry is to further notify the controller of the continuing state, on detection of at least one conversation continuing features to keep the dialogue engine from being prematurely deactivated prior to end of the conversation with the user;

    wherein detection for conversation continuing features include detection for at least selected pitch attributes of the user.
