Example Embodiment

[0042] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0043] like figure 1 As shown, the present invention has designed a kind of dynamic location monitoring method based on speech recognition, and this method can judge whether to be in dangerous situation according to the input speech signal, can determine its position in the first time when judging as dangerous. The method specifically includes the following steps:

[0044] Step 1. Real-time positioning to obtain current location data.

[0045] Step 2, input voice signal, and carry out preprocessing to voice signal to obtain voice digital signal; Preferably, to voice signal preprocessing such as figure 2 As shown, it includes processing processes such as filtering, pre-emphasis, framing and windowing, and endpoint detection. Among them, the specific steps of the preprocessing process are:

[0046] Step 2-1, performing anti-aliasing filtering processing.

Abstract

The invention discloses a dynamic positioning monitoring method and system based on speech recognition. The method comprises the steps of obtaining current position data through real-time positioning; inputting a speech signal, and performing preprocessing to obtain a speech digital signal; performing feature parameter extraction based on a linear prediction cepstrum coefficient (LPCC) on the speech digital signal, and obtaining speech signal parameters; building a speech template base composed of target sound templates; constructing an artificial neural network model, judging whether abnormity exists or not on the basis of recognition of speech feature parameters obtained through the built speech template base, and generating and sending a control signal when it is determined that abnormity exists; according to the control signal, sending the current position data. The system comprises a GPS module, a speech sensing module, a control module and a GSM module. The input speech signal can be recognized and judged, whether the danger condition exists or not is judged, the current position data of the user obtained through positioning can be sent for the first time, and monitoring real-time performance and accuracy are improved.

Description

technical field [0001] The invention relates to a voice recognition-based dynamic positioning monitoring method and system, belonging to the technical field of positioning monitoring. Background technique [0002] At present, according to statistics, 8 million people go missing in China every year, and nearly 10 million people are looking for them. And the number of missing and separated persons is still increasing. Including the accumulated lost population over the years, the number of missing persons is more than 10 million each year. With the rapid development of science and technology, there are more and more methods for high-tech equipment to solve security problems, and security issues are increasingly attracting people's attention. [0003] At the same time, GPS, as the latest positioning technology, is being widely used in military affairs, science, automobile positioning, and mobile phone positioning in our lives. The birth of GPS has brought about great changes i...
