[0028] The utility model discloses a voice control circuit for opening and closing a car door and a car.

[0031] In the above-mentioned voice control circuit for opening and closing of automobile door, the voice signal access module is respectively connected to the voice processing chip and the connector, and the control signal amplification module is respectively connected to the voice processing chip and the connector. The connector can provide the voice signal collected by the external sensor to the voice signal access module, and the voice signal access module can provide the voice signal provided by the connector to the voice processing chip; the voice processing chip can generate a control signal according to the voice signal provided by the voice signal access module, and provide the control signal to the control signal amplification module; the control signal amplification module can amplify the control signal provided by the voice processing chip, and provide the amplified control signal to the connector; the connector can provide the amplified control signal to the external circuit for opening and closing control of the automobile door.
