Embodiment Construction

[0013] Such as figure 1 and figure 2 The structural block diagram and work flow chart of the voice emergency system based on the Android mobile phone are shown. The system is installed in the Android mobile phone. The system includes a sound collection system, a signal filtering system, a speech recognition system, a sensitive word recognition system, a mobile phone vibrator and a keyword recognition system . The sound collection system includes a sound sensor and a signal amplifier. The signal filtering system mainly includes a band-pass filter, which filters the ambient sound and eliminates the interference signal.

[0014] The sound collection system is equivalent to a microphone, which collects and inputs the surrounding sound signals to the mobile phone. The sound sensor has a built-in condenser electret microphone sensitive to sound. Sound waves vibrate the electret membrane inside the microphone, causing a change in capacitance, which produces a corresponding chang...

Abstract

The invention relates to a voice help-seeking system based on an Android phone. The voice help-seeking system is installed in the Android phone; a sound transducer collects a voice signal and inputs the voice signal into the mobile phone, and then through a signal amplifier, the amplified voice signal is sent to a signal filter system to carry out signal filtration; the filtered voice signal is sent to a voice recognition system to recognize the decibel and the frequency of the sound and the high pitch of an owner; the voice signal which is determined within the recognition range is sent to a sensitive word recognition system to carry out help-seeing content screening; after a sensitive word is judged, the vibrator of the mobile phone is triggered to vibrate to give an alarm; a keyword recognition system recognizes keywords in a contact list of the mobile phone, and after recognition, the communication information of the keyword person is called and an alarm short message is sent, and the position of the mobile phone is displayed through a GPS (Global Positioning System) positioning function. When the Internet is not connected, the voice help-seeking function can be normally used, and the safety of the user of the mobile phone is protected in real time, so that the condition that people in the face of danger cannot seek help through the mobile phone is solved.

Description

technical field [0001] The invention relates to an alarm system, in particular to a voice emergency system based on an Android phone. Background technique [0002] In response to the terrorist attacks in Paris, when people are in danger, they call for help as soon as possible. Hands and feet may not be able to call the police for help through the mobile phone at the first time. When becoming a hostage, the hands and feet may be bound, making it impossible to use mobile phones and other alarm tools. [0003] In terms of medical care, when a sudden illness occurs and people cannot touch tools such as mobile phones, they need to call for help through voice. [0004] In the face of natural disasters, people may be trapped in a small environment, and the mobile phone isolation distance is far away and cannot be touched, so they need to ask for help through voice. Contents of the invention [0005] The present invention is aimed at the problem that the crisis is nothing more ...
