WIPO Patent Application WO/2020/244355

A1

A smart electronic device having a built-in microphone; the smart electronic portable device performs voice input-based interaction with a user by means of the following operations: processing a sound signal captured by a microphone to determine whether a voice signal is present in the sound signal; in response to confirming that a voice signal is present in the sound signal, further determining on the basis of the sound signal collected by the microphone whether the distance between the smart electronic device and the mouth of the user is less than a predetermined threshold; and in response to determining that the distance between the electronic device and the mouth of the user is less than the predetermined threshold, using the sound signal collected by the microphone as a voice input and processing same. The described interaction method is suitable for a user performing voice input while carrying a smart electronic device, operation being natural and simple; in addition, the step of voice input is simplified, and the burden and difficulty of interaction are reduced so that interaction is more natural.
