Information service apparatus and information service method
First Claim
1. An information service apparatus which comprises display means for displaying text information, and can be connected to an audio output device that can output speech information corresponding to the text information, comprising:
- determination means for determining if the audio output device is connected; and
switching control means for making output destination switching control that outputs the speech information corresponding to the text information to the audio output device when said determination means determines that the audio output device is connected, and outputs the text information to the display means when said determination means determines that the audio output device is not connected.

Abstract
An information output method switching unit (105) checks whether or not an audio output device (103) is connected to an audio output device connection unit (104). When the audio output device (103) is connected to an information service apparatus, the information output method switching unit (105) sends text information stored in an information holding unit (102) to a text-to-speech synthesis unit (106), which generates synthetic speech using a known text-to-speech synthesis technique, and sends the generated synthetic speech to the audio output device connection unit (104). On the other hand, when the audio output device (103) is not connected to the information service apparatus, the information output method switching unit (105) sends text information stored in the information holding unit (102) to an information display output unit (107), which displays the received text information.
