Embodiment 1
[0019] figure 1 A flow chart of a method for alarming according to a sound source in an embodiment of the present invention, the method includes the following steps:
[0020] S101, pre-recording the first sound source, analyzing the acoustic characteristics of the first sound source to determine the acoustic parameters of the first sound source, the acoustic parameters include: waveform, fundamental frequency, sound intensity, sound length and pronunciation speed; set the alarm threshold value of each acoustic parameter and the alarm threshold value of the second sound source duration, and use the first sound source, the corresponding acoustic parameter of the first sound source and the alarm threshold value of each acoustic parameter as the first sound source A sound source information is stored;
[0021] The first sound source is a word or cry that the user has a high probability of uttering in an emergency and can identify acoustic parameters, and according to the first so...
Embodiment 2
[0039] figure 2 It is a structural schematic diagram of an alarm system based on a sound source according to an embodiment of the present invention.
[0040] The system includes: a pre-recording module, a real recording module, and an alarm module;
[0041] The pre-recording module is connected with the actual recording module, and is used for pre-recording the first sound source, analyzing the acoustic characteristics of the first sound source to determine the acoustic parameters of the first sound source, and the acoustic parameters include: waveform, basic Frequency, sound intensity, sound length and pronunciation speed; set the alarm threshold value of each acoustic parameter and the alarm threshold value of the duration of the second sound source, and set the first sound source, the corresponding acoustic parameters of the first sound source and each The alarm threshold value of an acoustic parameter is stored as the first sound source information;
[0042] The first s...
