NAVIGATION DEVICE, SERVER, NAVIGATION METHOD AND PROGRAM

摘要

When a navigation device receives an input of speech from a user, it transmits data of inputted speech to a server and receives a speech recognition result. If a guide route includes a communication impossible area, the navigation device obtains terminal-use speech recognition data necessary for the navigation device to perform speech recognition from the server before reaching the communication impossible area. Thus, even if the speech is inputted by the user while traveling the communication impossible area, the navigation device can perform the speech recognition by itself by using the terminal-use speech recognition data.

主权项

1. A navigation device which performs navigation along a guide route to a destination, comprising:
a speech input unit which receives an input of speech; a transmitting unit which transmits data of inputted speech to a server; a receiving unit which receives a speech recognition result of the data of the inputted speech from the server; and an obtaining unit which obtains terminal-use speech recognition data necessary for recognition of the inputted speech from the server, before reaching a communication impossible area where communication with the server is impossible, in a case where the guide route includes the communication impossible area.
