Problems solved by technology

But these service robots are expensive, the cost is too high, and they are inconvenient to use, so they cannot meet the actual needs
[0004] In addition, there are currently blind navigation devices designed for the visually impaired on the market, but such blind navigation devices can only be used to guide users, and cannot inform users of abnormal conditions in the surrounding environment.

Embodiment Construction

[0017] Such as figure 1 Shown is the application environment diagram of the preferred embodiment of the sound detection notification system of the present invention. The sound detection notification system 12 runs in the mobile device 1 , and the mobile device 1 also includes a voice model database 11 , a central processing unit 13 , an electronic compass 14 , a microphone 15 and a display screen 16 . In this embodiment, the speech model database 11 is used to store characteristic parameters of speech recognition and different types of sound models, wherein the different types of sound models include: human voice models and vehicle horn sound models.

[0018] The central processing unit 13 is used to invoke the sound detection notification system 12 and control the execution of the sound detection notification system 12 . The sound detection and notification system 12 is used to acquire the ambient sound detected by the microphone 15 in real time when the mobile device 1 is a...

Abstract

The invention discloses a method for sensing and notifying voice. The method comprises the following steps of: receiving a voice signal sensed by a microphone, and calculating energy of the voice signal; when the energy of the voice signal is greater than the preset value, judging the direction of the voice source according to the energy of the voice signal; determining the type of the voice signal according to the characteristic parameters of the voice identification and different types of voice models which are stored in a voice model database; and sending early warning information according to the type of the voice and notifying a user of the direction of the voice source. By the method, voice of the surrounding environment can be sensed in real time, and early warning information can be sent to the user when the abnormal condition occurs.

Description

technical field [0001] The present invention relates to a sound detection system and method, in particular to a sound detection notification system and method. Background technique [0002] When the hearing-impaired or visually-impaired walk on the road, if there are vehicles honking their horns around them, or others calling them, they may not be able to detect them in time, so it will bring some inconvenience. It is also a big hidden danger. [0003] At present, there are electronic devices on the market that can distinguish location by sound, such as service robots such as listening robots and following robots. Using these service robots can help the hearing-impaired or visually-impaired to determine the direction of the sound source. However, these service robots are expensive, cost too high, and are inconvenient to use, so they cannot meet actual needs. [0004] In addition, there are currently blind navigation devices designed for the visually impaired on the market,...
