The invention discloses a physical sign detection method and system. The physical sign detection method comprises the following steps: S1, acquiring a voice starting instruction of a user; s2, forming a voiceprint feature vector of the starting voice instruction according to the starting voice instruction; s3, matching the voiceprint feature vector for starting the voice instruction with a voiceprint vector of a target user in a voiceprint model library one by one, and obtaining a matching degree score; and S4, when the obtained highest matching degree score is greater than or equal to a first set threshold value, starting the physical sign detection device. The physical sign detection system comprises a voice acquisition module, a voiceprint feature vector forming module, a voiceprint vector matching module and a threshold comparison module. The user can complete identification of the target user and starting of the physical sign detection device only by sending the starting voice instruction, and the proble
