<0A>HotwordDetectorab
    Snowboy decoder to detect whether a keyword specified by `decoder_model`
    exists in a microphone input stream.

    :param decoder_model: decoder model file path, a string or a list of strings
    :param resource: resource file path.
    :param sensitivity: decoder sensitivity, a float of a list of floats.
                              The bigger the value, the more senstive the
                              decoder. If an empty list is provided, then the
                              default sensitivity in the model will be used.
    :param audio_gain: multiply input volume by this factor.

        Start the voice detector. For every `sleep_time` second it checks the
        audio buffer for triggering keywords. If detected, then call
        corresponding function in `detected_callback`, which can be a single
        function (single model) or a list of callback functions (multiple
        models). Every loop it also calls `interrupt_check` -- if it returns
        True, then breaks from the loop and return.

        :param detected_callback: a function or list of functions. The number of
                                  items must match the number of models in
                                  `decoder_model`.
        :param interrupt_check: a function that returns True if the main loop
                                needs to stop.
        :param float sleep_time: how much time in second every loop waits.
