(2) Two voice phrases are preset for the voice recognition module to be used as a primary secret setting language and a secondary secret setting language respectively.
(3) The voice recognition module detects a built-in microphone in a polling mode, and if voice signal input is detected, the voice recognition module is matched with a preset first-level setting secret language. If the primary matching is not successful, whether the microphone has secret language input or not is continuously detected. If the first-stage matching is successful, the microphone is detected again, if the voice signal input is detected again, the voice signal detected again is matched with the secret words of the second set stage, and if the second-stage matching is successful and the time interval of the voice signal input by the first-stage matching is within the set time period, an alarm request signal is sent to the microcontroller.

1) by adopting secret language alarm instead of plain language, the alarm can be finished under the condition of not causing the alertness of others. The voice recognition module can preset voice phrases as alarm secret words. This advantage stems from the language identification module and the microcontroller.
2) Each user can adopt different secret setting words as alarm secret words, and the safety and the reliability of the secret words are improved. The alarm adopts a non-specific person voice recognition module, and does not need specific voice and tone. This advantage stems from the language identification module and the microcontroller.
3) And by adopting a second-level secret language, false alarm is effectively prevented. The voice recognition module of the alarm adopts two-stage whispering, and only in a set time period (namely, a time interval of sending whispering voice signals twice), the two whispering voice signals are successfully matched to send an alarm request signal. This advantage stems from the language identification module and the microcontroller.
