Claims

[Scope of utility model registration request]

(1) A voice recognition circuit that recognizes a voice control signal from the voice input section and outputs a control signal corresponding to the voice control signal; In a vehicle voice recognition device that controls in-vehicle equipment using control signals from a recognition circuit, a noise input section;
The noise signal from the noise input section is input and the SN of the noise signal is
and a comparison circuit that compares the ratio with a reference SN ratio corresponding to a desired recognition rate, and only when the SN ratio of the noise signal is equal to or higher than the reference SN ratio corresponding to the desired recognition rate, A voice recognition device for a vehicle, characterized in that an indicator light or an alarm is operated based on a comparison signal.

(2) Scope of Utility Model Registration Claims (1) In the apparatus described in (1), the standard S is such that the S/N ratio of the noise signal corresponds to a desired recognition rate.
A voice recognition device for a vehicle, wherein the voice recognition circuit enters a recognition enabled state based on a comparison signal from a comparison circuit only when the N ratio is greater than or equal to the N ratio.
