Voice navigation method

Abstract

The invention discloses a speech navigation method, suitable for an electronic device. The method comprises that a satellite location signal is received; then the satellite location signal is coded; and the current location data is obtained. A built-in destination is read and a suggestion path is obtained by conducting the path calculation of the current location data and the destination, and whether the distance between the current location data and a specific establishment is within a preset distance or not can be judged. When the distance between the current location data and a specific establishment is judged to be within a preset distance, a passing direction speech is sent out. When a sight handicapped people walks to the specific establishment with the invention, he or she can listen to the reminding speech for changing the walking mode; and the sight handicapped people can promote the alert in advance and concentrate the attention with the invention. At the same time, the sight handicapped person is reminded to change the walking mode to pass or enter into the specific establishment, which ensures the safety of walking. And the invention can also reduces the difficulty during the walking of the sight handicapped people, which increases the moving freedom and promotes the convenience during the walking of the sight handicapped people greatly.

Description

technical field [0001] The invention relates to a voice navigation method, in particular to a navigation method capable of issuing voice prompts to guide users through special facilities. Background technique [0002] The application of mobile phones has tended to multi-functional development, such as combining digital cameras, personal digital assistants (Personal Digital Assistant, PDA), global satellite positioning system (Global Position System, GPS), etc., to provide users with different functional requirements. [0003] For the general public who use mobile phone screens as feedback, the operation design of mobile phones has become more complete and can be easily operated. However, due to market appetite and technical considerations, the inconvenience encountered by the visually impaired in using mobile phones has always been neglected phenomenon. For the visually impaired, there are still only two basic functions that can be used: answering and dialing. The design c...

Problems solved by technology

At this time, if the satellite navigation device or the mobile phone does not have a voice prompt function to prompt, the visually impaired may change their walking mode because they cannot respond to the road conditions of the special facility, and the road safety of the visually impaired cannot be guaranteed, and the freedom of movement is also limited. lower

[0006] According to the above-mentioned prior art, when the visually impaired walk to special facilities, the navigation device cannot change the voice prompt in response to the road conditions to remind the visually impaired to change the walking mode, causing the visually impaired to have safety concerns when walking
