  "textContent": "A delay estimation method for a smart rearview mirror, a delay estimation apparatus for a smart rearview mirror, and an electronic device are provided. Identification information of an external device is obtained (101) in response to connecting to the external device by a smart rearview mirror for screen projection. A target delay estimation upper limit corresponding to the external device is obtained (102) based on the identification information. A delay estimation result is obtained (103) by performing delay estimation based on the target delay estimation upper limit in response to sending a voice signal by the smart rearview mirror to the external device. The delay processing is performed (104) on the voice signal based on the delay estimation result.",
