Abstract

In an in-vehicle navigation apparatus, an in-vehicle BT communications device receives a speech recognition result via a BT communications link from a cellular phone. Based on the received speech recognition result, an in-vehicle control circuit outputs a talk-back sound about the speech recognition result via an in-vehicle sound output device.

Claims

1. An information presentation system including an in-vehicle apparatus in a vehicle and a portable terminal that performs data communications with the in-vehicle apparatus,

the portable terminal performing a display based on display related information according to a function of the portable terminal itself,

the in-vehicle apparatus comprising

a sound output device which outputs a sound,

a data acquisition device which acquires the display related information from the portable terminal through the data communications, and

an output control section configured to cause the sound output device to output a sound according to the function of the portable terminal, based on the display related information according to the function of the portable terminal acquired by the data acquisition device.

2. The information presentation system according to claim 1, further comprising:

a speech recognition server which has a dictionary for speech recognition,

the portable terminal comprising

a sound input device which receives an input of a speech command from a user, and

a display device which displays information,

the portable terminal transmitting to the speech recognition server speech data of the speech command of which the input is received by the sound input device,

the portable terminal performing in the display device a display according to a speech recognition result that is obtained in the speech recognition server by performing a speech recognition based on the speech data using the dictionary,

the data acquisition device of the in-vehicle apparatus acquiring the speech recognition result from the portable terminal as the display related information through the data communications,

the output control section of the in-vehicle apparatus device causing the sound output device to output a talk-back speech according to, the speech recognition result based on the display related information acquired by the data acquisition device.

3. The information presentation system according to claim 2,

the speech recognition server

executing the speech recognition based on the speech data, and

obtaining at least text data as the speech recognition result,

the output control section of the in-vehicle apparatus

executing a speech synthesis according to the text data as the speech recognition result acquired by the data acquisition device to obtain a synthesized speech, and

causes the sound output device to output as a talk-back speech the synthesized speech obtained by executing the speech synthesis.

4. The information presentation system according to claim 2,

the speech recognition server

executing the speech recognition based on the speech data, and

obtaining at least phoneme data as the speech recognition result,

the output control section of the in-vehicle apparatus

executing a speech synthesis according to the phoneme data as the speech recognition result acquired by the data acquisition device to obtain a synthesized speech, and

causing the sound output device to output as a talk-back speech the synthesized speech obtained by executing the speech synthesis.

5. The information presentation system according to claim 2,

the sound output device of the in-vehicle apparatus outputting an in-vehicle apparatus-side usual sound, which is other than the talk-back speech and is according to a function of the in-vehicle apparatus,

the in-vehicle apparatus comprising an output determination section configured to determine whether the in-vehicle apparatus-side sound is under output via the sound output device of the in-vehicle apparatus,

wherein

in case that the output determination section determines that the in-vehicle apparatus-side sound is under output when the output control section outputs the talk-back speech via the sound output device,

the output control section of the in-vehicle apparatus mutes an output of the in-vehicle apparatus-side usual sound before causing the sound output device to output the talk-back speech.

6. The information presentation system according to claim 2,

the sound output device of the in-vehicle apparatus outputting an in-vehicle apparatus-side usual sound, which is other than the talk-back speech and is according to a function of the in-vehicle apparatus,

the in-vehicle device comprising a priority storage device to store a priority order with respect to each of kinds of sounds outputted via the sound output device,

the output control section outputting a sound, which indicates the speech recognition result and is higher in the priority order than the talk-back speech, in priority to the talk-back speech based on the priority order stored in the priority storage device, even while the talk-back speech is under output via the sound output device.

7. The information presentation system according to claim 2,

the portable terminal outputting a portable terminal-side usual sound, which is one of a guide sound and a warning sound according to a function of the portable terminal,

the in-vehicle apparatus comprising a sound signal acquisition device to acquire a sound signal of the portable terminal-side usual sound through the data communications from the portable terminal,

the output control section of the in-vehicle apparatus causing the sound output device to output the portable terminal-side usual sound based on the sound signal acquired by the sound signal acquisition device.
