Claim 5:
6. A speech control method, comprising:
collecting audio data and recognizing a wake-up word from the collected audio data in a standby state;
waking up in response to recognizing the wake-up word;
taking audio data collected within a target duration before wake-up and audio data collected after wake-up as target audio data and sending the target audio data to a server;
in which, the target audio data is configured for speech recognition, and to control based on an instruction recognized from a second audio segment of the target audio data in response to recognizing a wake-up word from a first audio segment at beginning of the target audio data; in which, the second audio segment is later than the first audio segment or has an overlapping portion with the first audio segment, wherein a duration of the first audio segment is greater than the target duration;
wherein the method further comprises:
deleting an audio segment of the target duration at a beginning position of the target audio data to acquire retained audio data in response to not recognizing the wake-up word from the first audio segment, or not recognizing the instruction from the second audio segment;
re-performing speech recognition on the retained audio data to obtain a re-devised first audio segment and a re-devised second audio segment; and
controlling the client based on an instruction recognized from the re-divided second audio segment.
