Abstract
A navigation system comprises a voice signal synthesizing section 33 which generates a voice signal from a text-based document, a speaker 17 which outputs the voice signal generated in the voice signal synthesizing section 33 as a voice, a drive circuit 18 thereof, a grasping section 31 which grasps a length of the text-based document, and a synthesizing control section 32 which allows the voice signal synthesizing section 33 to generate a voice signal an intonation of which has been changed. According to the navigation system, it is possible to enhance a sense of realism in voice output regarding plural types of sentence.
Claims6
A voice output unit which converts a text-based document into a voice and outputs the voice, comprising,
- a voice signal synthesizer for generating a voice signal from said text-based document,
- an output means which outputs as a voice said voice signal generated in said voice signal synthesizer,
- a grasping means which grasps contents or a length of said text-based document, and
- a synthesizing controller for allowing said voice signal synthesizer to generate said voice signal in which a tone quality including at least intonation is changed, according to the contents or the length of said text-based document grasped in said grasping means, when said voice signal synthesizer generates said voice signal from said text-based document.
A navigation system which converts a corresponding text-based document into a voice according to a situation what kind of voice is to be outputted, and outputs the voice, comprising,
- a voice signal synthesizer for generating a voice signal from said text-based document,
- an output means which outputs as a voice said voice signal generated by said voice signal synthesizer,
- a grasping means which grasps said situation, and
- a synthesizing controller for allowing said voice signal synthesizer to generate said voice signal in which a tone quality including at least one of intonation, volume, speed and key is changed, according to said situation grasped in said grasping means, when said voice signal synthesizer generates said voice signal from said text-based document.
