Speech reception device, speech reception method, and computer program for speech reception

Abstract

When receiving a vehicle driver's utterance, the system appropriately requests additional utterances. [Solution] The voice reception device includes a recognition unit that recognizes the content of a vehicle driver's utterance based on data representing the content of the utterance; a determination unit that determines the degree to which the driver is required to monitor the surrounding conditions of the vehicle; and a setting unit that sets the frequency of additional utterance requests, which request further utterances from the driver in response to the driver's utterance, to decrease as the level of monitoring increases. The voice reception method includes receiving utterances from a vehicle driver, determining the degree to which the driver is required to monitor the surrounding conditions of the vehicle, and setting the frequency of additional utterance requests, which request further utterances from the driver in response to the driver's utterance, to decrease as the level of monitoring increases.

Claims

1. A recognition unit recognizes the content of a vehicle driver's speech based on data representing the content of the speech, A determination unit that determines the degree to which the driver is required to monitor the surrounding conditions of the vehicle, A setting unit that sets the frequency of additional speech requests, which request further speech from the driver in response to the driver's speech, to decrease as the level of monitoring increases, A speech reception device equipped with the following features.

2. The speech reception device according to claim 1, wherein the setting unit sets the monitoring level lower the higher the autonomous driving level, which represents the degree to which the control of the vehicle's movement is assisted by the driving control device.

3. The speech reception device according to claim 1, wherein the setting unit sets the level of monitoring higher the more traffic participants there are around the vehicle.

4. The speech receiving device according to any one of claims 1 to 3, further comprising an inquiry unit that causes the additional speech request to be output to an output device mounted on the vehicle according to the frequency.
