Description

A dialogue device for normal people and deaf, dumb and blind people and its application method

technical field

The invention belongs to the technical field of speech recognition, and in particular relates to a dialogue device for a normal person and a deaf, dumb, and blind crowd and a use method thereof, and is especially suitable for hearing-impaired, speech-impaired, and visually-impaired crowds.

Background technique

Today, due to the effects of disease, genetics, toxic drugs, noise, accidents, and an aging population, the number of people with hearing impairment, speech impairment, and visual impairment is on the rise. These have affected people's normal life and brought misery and poverty to many families. Hearing impairment, speech impairment, and visual impairment have not only become global public health problems, but also increasingly serious social problems.

At present, there are also some technical solutions to solve this type of problem in the prior art, specifically:

The invention patent with the patent number [200410026265.5] discloses a pressure-changing skin hearing device. According to the biological hearing principle, it uses electronic and acoustic technology to imitate the auditory organ of the human body, and provides a skin hearing device that is convenient for deaf-mute people to use. device. The invention converts external sound signals into current signals, and transmits the current oscillating signals to the brain through the skin, so that hearing-impaired users can feel the stimulation signals, but it does not solve the problem of speech recognition.

The invention patent with the patent number [200910219078.1] discloses a "multi-channel array skin hearing device", which provides a multi-channel band-pass filter and power amplifier circuit connected to a booster array device to drive a planar electrode array to stimulate the skin The way of different positions enables the skin to have the ability of speech discrimination. This invention needs to restore complex speech to multiple relatively simple audio signals, and realize speech discrimination by stimulating different positions of the human body with different frequency signals. This process requires hearing-impaired users to undergo long-term language conditioning and repeated training before they can complete the memory of different stimuli produced by various voice signals. Therefore, there are many types of stimuli required for memory, and it takes a long time to form conditioned reflexes, making the speech recognition process complicated and difficult.

The invention patent with the patent number [201110245914.0] discloses a voice recognition method for hearing-impaired people. The received voice information is converted into Chinese character information through a microprocessor, and combined with the Chinese character location code table to convert it into digital information from 0 to 9 , according to the location code, according to the specific skin stimulation scheme, to realize the speech recognition of the hearing-impaired people. Although there are few kinds of stimuli to memorize, the time required to form a conditioned reflex is short, and the speech recognition process is simple, it still requires hearing-impaired people to memorize "stimulus codes".

Contents of the invention

In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a kind of dialogue device between normal people and deaf, dumb and blind people and its use method, and convert the voice information sent by normal people into Chinese character information by microprocessor , combined with Chinese characters and then converted into Braille information, and then the Braille information is converted into the corresponding Braille convex-convex array through the corresponding array driver, for the deaf, dumb, and blind people to touch and sense; when the deaf, dumb, and blind people talk to normal people, they can Braille is written on the device, and the microprocessor can convert the Braille into the corresponding voice and play it to normal people; the invention uses a microprocessor to convert the voice and the corresponding Braille convex-convex array, which solves the problem that the deaf, dumb, and blind people cannot communicate with normal people. communication problem.

In order to achieve the above object, the technical solution adopted by the present invention is: a dialogue device for normal people and deaf, dumb and blind people, including a microprocessor, a voice processor and a voice converter are arranged in the microprocessor, voice processing The device is connected to the audio amplifier through the speech recognition device; the output end of the speech processor is connected to the array driver through the braille converter A; the output end of the voice converter is connected to the voice player; the input end of the voice converter is connected to the array driver through the braille converter B Braille writing device connected.

A method for using a dialogue device between normal people and deaf, dumb and blind people, comprising the following steps:

First, collect the voice signal and preprocess it through the audio amplifier. The specific method is:

Use the microphone to collect the voice signal of normal people, and amplify the collected signal through the audio amplifier;

Second, the amplified voice signal is recognized by a voice recognition device, and then converted into a corresponding Chinese character code by a voice processor;

Third, the Chinese character code is converted into corresponding Braille information by the Braille converter A, and then the Braille information is converted into convex-concave Braille by the array converter and displayed on the device, and the convex-concave Braille converted by the array converter is buffered in the buffer. The speed of appearance is for the deaf, dumb and blind to touch, and it is convenient for the deaf, dumb and blind to touch, so as to achieve the purpose of speech recognition;

Fourth, the deaf, dumb and blind write Braille on Braille writing devices;

Fifth, the Braille converter B in the microprocessor converts the written Braille into Braille information;

Sixth, Braille information is converted into voice through a voice converter, and played to normal people through a voice player.

The beneficial effects of the present invention are:

The invention converts the voice information sent by normal people into Chinese character information through a microprocessor, and combines Chinese characters into Braille information, and then converts the Braille information into a corresponding Braille convex-convex array through a corresponding array driver, for the deaf, dumb, and blind. Group touch perception; when the deaf, dumb, and blind people talk to normal people, they can write Braille on the dialogue device, and the microprocessor can convert Braille into corresponding voice and play it to normal people. The invention uses a microprocessor to convert voice and corresponding Braille convex-convex arrays, which solves the problem that deaf, dumb and blind people cannot communicate with normal people.
