Abstract
A personal mobility vehicle, such as a wheelchair system, includes an input audio transducer having an output coupled to a speech recognition system and an output audio transducer having an input coupled to a speech synthesis system. The wheelchair system further includes a control unit having a data processor and a memory. The data processor is coupled to the speech recognition system and to the speech synthesis system and is operable in response to a recognized utterance made by a user to present the user with a menu containing wheelchair system functions. The data processor is further configured in response to at least one further recognized utterance made by the user to select from the menu at least one wheelchair system function, to activate the selected function and to provide audible feedback to the user via the speech synthesis system.
