20090213727 | VOICE PACKET COMMUNICATIONS SYSTEM WITH COMMUNICATIONS QUALITY EVALUATION FUNCTION - A voice packet communications system which objectively evaluates the voice quality in real time. Voice packets received from a network are input into an adjustment circuit. The adjustment circuit evens out the periods of the voice packets, detects the drop-out of voice packets, and inserts substitute packets in the voice packet sequence. Furthermore, the adjustment circuit outputs the number of voice packets that have dropped out, the number of substitute packets that have been inserted, and the number of voice packets that have accumulated inside the circuit, as quality information in each monitoring period. A decoding circuit converts the voice packets adjusted by the adjustment circuit into voice information. A judgement circuit calculates an index that indicates the communications quality of the voice packets from the quality information using a specified calculation formula. | 08-27-2009 |

20150106013 | NAVIGATION DEVICE, SERVER, NAVIGATION METHOD AND PROGRAM - 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. | 04-16-2015 |
