The present disclosure provides a method, an apparatus and a device for implementing a voice application and a computer readable storage medium, which determine a feedback content and a template identifier corresponding to a voice command of a user on a server side, and the determination result is performed by the IoT device. As the Internet information is iteratively updated, the voice command is also updated, the processing function of the voice command can be updated on the server side, so that the voice application in the IoT device does not need to be updated. Therefore, the processing capability of the voice application can be updated without upgrading the voice application itself, thereby alleviating the problem of an excessively long upgrade process due to the OTA upgrade process in the prior art.
