Abstract

When electric field strength of a reception signal becomes less than a threshold level, an in-vehicle terminal executes one of three operations. The first is that the in-vehicle terminal prohibits input of a voice. The second is that the in-vehicle terminal transmits an inputted voice with a datum indicating radio wave environment to a voice recognition server. The third is that the in-vehicle terminal once stores the inputted voice, and then transmits the inputted voice that has been stored after the electric field strength of the reception signal exceeds the threshold level.

Claims (78)

1. A terminal that is provided in a vehicle and constitutes a voice recognition system with a voice recognition server that executes voice recognition for a voice received from the terminal via wireless communication, the terminal comprising:

voice inputting means for inputting the voice;

storing means for storing the inputted voice;

transmitting means for transmitting the stored voice to the voice recognition server;

determining means for determining whether a radio wave environment relating to the wireless communication meets a certain condition; and

controlling means for controlling the storing means for storing the inputted voice when it is determined that the radio wave environment does not meet the certain condition, and the transmitting means for transmitting the stored voice to the voice recognition server after it is determined that the radio wave environment meets the certain condition;

wherein the stored voice is transmitted to the voice recognition server along with an elapse datum indicating an elapsed time from a time when the inputted voice is stored by the storing means.

2. A terminal according to claim 1 , further comprising:

notifying means for executing notification,

wherein the controlling means controls the notifying means for executing notification so as to clarify determination by the determining means.

3. A voice recognition server for voice recognition for a voice transmitted via wireless communication from a terminal that is provided in a vehicle and includes:

voice inputting means for inputting the voice;

transmitting means for transmitting the inputted voice to the voice recognition server;

determining means for determining whether at least one case of two cases is unfulfilled, wherein a first case is that a radio wave environment relating to the wireless communication meets a certain condition and a second case is that a state of the vehicle meets a given condition; and

controlling means for controlling the transmitting means for transmitting, when at least one case of the two cases is determined to be unfulfilled, to the voice recognition server the inputted voice along with a reference datum indicating one item of two items of the radio wave environment and the state of the vehicle, wherein the one item corresponds to the one case that is determined to be unfulfilled,

the voice recognition server comprising:

receiving means for receiving the voice along with the reference datum transmitted from the terminal;

determining means for determining whether the reference datum meets a predetermined condition; and

voice recognition means for executing, when it is determined that the reference datum meets the predetermined condition, the voice recognition for the received voice.

4. A voice recognition server for voice recognition for a voice transmitted via wireless communication from a terminal that is provided in a vehicle and includes:

voice inputting means for inputting the voice;

storing means for storing the inputted voice;

transmitting means for transmitting the stored voice to the voice recognition server;

determining means for determining whether a radio wave environment relating to the wireless communication meets a certain condition; and

controlling means for controlling the storing means for storing the inputted voice when it is determined that the radio wave environment does not meet the certain condition, and the transmitting means for transmitting the stored voice to the voice recognition server after it is determined that the radio wave environment meets the certain condition, wherein the stored voice is transmitted to the voice recognition server along with an elapse datum indicating an elapsed time from a time when the inputted voice is stored by the storing means,

the voice recognition server comprising:

receiving means for receiving the voice along with the elapse datum transmitted from the terminal;

determining means for determining whether the elapse datum meets a predetermined condition; and

voice recognition means for executing, when it is determined that the elapse datum meets the predetermined condition, the voice recognition for the received voice.

5. A voice recognition system for a voice uttered in a vehicle, comprising:

a terminal that is provided in the vehicle and accepts the voice; and

a voice recognition server that is for executing voice recognition for the voice transmitted via wireless communication from the terminal,

wherein the terminal includes:

voice inputting means for inputting the voice;

transmitting means for transmitting the inputted voice to the voice recognition server via the wireless communication;

determining means for determining whether at least one case of two cases is unfulfilled, wherein a first case is that a radio wave environment relating to the wireless communication meets a certain condition and a second case is that a state of the vehicle meets a given condition; and

controlling means for controlling the transmitting means for transmitting, when at least one case of the two cases is determined to be unfulfilled, to the voice recognition server the inputted voice along with a reference datum indicating one item of two items of the radio environment and the state of the vehicle, wherein the one item corresponds to the one case that is determined to be unfulfilled, and

wherein the voice recognition server includes:

receiving means for receiving the voice along with the reference datum transmitted from the terminal;

determining means for determining whether the reference datum meets a predetermined condition; and

voice recognition means for executing, when it is determined that the reference datum meets the predetermined condition, the voice recognition for the received voice.

6. A voice recognition system for a voice uttered in a vehicle, comprising: a terminal that is provided in the vehicle and accepts the voice; and

a voice recognition server that is for executing a voice recognition for the voice transmitted via wireless communication from the terminal,

wherein the terminal includes:

voice inputting means for inputting the voice;

storing means for storing the inputted voice;

transmitting means for transmitting the stored voice to the voice recognition server;

determining means for determining whether a radio wave environment relating to the wireless communication meets a certain condition; and

controlling means for controlling the storing means for storing the inputted voice when it is determined that the radio wave environment does not meet the certain condition, and the transmitting means for transmitting the stored voice to the voice recognition server after it is determined that the radio wave environment meets the certain condition, wherein the stored voice is transmitted to the voice recognition server along with an elapse datum indicating an elapsed time from a time when the inputted voice is stored by the storing means, and

wherein the voice recognition server includes:

receiving means for receiving the voice along with the elapse datum transmitted from the terminal;

determining means for determining whether the elapse datum meets a predetermined condition; and

voice recognition means for executing, when it is determined that the elapse datum meets the predetermined condition, the voice recognition for the received voice.

7. A computer-readable medium comprising a computer program for a terminal that is provided in a vehicle and constitutes a voice recognition system with a voice recognition server that executes voice recognition for a voice inputted from the terminal, the computer program comprising instructions for:
