Abstract: The examples relate to implementations of apparatuses, such as lighting devices, and a system that uses a speech-based user interface to provide speech-based navigation services. The speech-based user interface provides navigation instructions that direct a person to the location of an item within a premises. The person interacts with a speech-based apparatus to receive the navigation instructions as speech-based directions through the premises from a specified location to the item location, or as static navigation instructions enabling the person to navigate from the specified location to the item location. A directional microphone and a controllable speaker receive audio inputs from and output audio outputs to a specified location or subarea of the premises to a person using the speech-based user interface. The audio outputs are directed to the person in the subarea of the premises, and have a higher amplitude within the subarea than outside the subarea of the premises.
