Abnormal emotion speech recognition-based wearable intelligent safety device and control method

Abstract

The present invention discloses an abnormal emotion speech recognition-based wearable intelligent safety device and a control method. The intelligent device comprises a main control module, a speech acquisition module, an analog-to-digital conversion module, a communication module and a positioning module. The control method is characterized by acquiring and processing the speech signals, extracting the speech characteristics, inputting the extracted characteristic parameters to a trained Gaussian mixture model for mode matching, and when the abnormal emotion speech is detected, starting a positioning early warning function, and comprises the concrete flows of S1 speech signal acquisition; S2 speech signal pre-processing; S3 speech end point detection; S4 speech signal characteristic extraction; S5 an abnormal emotion speech recognition stage; S6 a positioning early warning stage. The wearable intelligent safety device of the present invention triggers the early warning automatically via the abnormal emotion speech of sufferers, such as the cry, the scream, the call for help, etc., when an emergency situation occurs, thereby guaranteeing the personal safety of the wearers.

Description

technical field [0001] The invention relates to the research field of wearable devices, in particular to a wearable intelligent safety device and a control method based on abnormal emotion speech recognition. Background technique [0002] Nowadays, personal safety accidents of women and young children occur frequently, which has aroused the public's attention to the safety of these vulnerable groups. When these vulnerable groups encounter violations, they are often unable to call the police in time due to excessive nervousness, fear or restraint, which greatly hinders the detection of the case and makes it difficult to guarantee the personal safety of the victims. When the victim loses the ability to call the police on his own, relatives can only wait until the missing time reaches 24 hours before filing a report. However, this way of handling misses the golden time to rescue the victim, causing immeasurable losses to the victim. [0003] At present, there is no wearable sm...
