Delay estimation method and apparatus for smart rearview mirror, and electronic device

An electronic device, comprising:

• at least one processor;
• and
• a memory, communicatively connected to the at least one processor;
• wherein,
• the memory stores instructions executable by the at least one processor, and when the instructions are executed by the at least one processor, the at least one processor is configured to:
• obtain identification information of an external device in response to connecting with the external device by a smart rearview mirror for screen projection;
• determine a target delay estimation upper limit corresponding to the external device based on the identification information;
• obtain a delay estimation result by performing a 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;
• and
• perform a delay processing on the voice signal based on the delay estimation result.

A non-transitory computer-readable storage medium storing computer instructions, wherein the computer instructions are configured to cause a computer to execute a delay estimation method, the method comprising:

• obtaining identification information of an external device in response to connecting with the external device by a smart rearview mirror for screen projection;
• determining a target delay estimation upper limit corresponding to the external device based on the identification information;
• obtaining a delay estimation result by performing a 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;
• and
• performing a delay processing on the voice signal based on the delay estimation result.
