Problems solved by technology

However, not all external sounds are meaningful to the deaf, and the existing sound recognition aids will respond to all sounds that reach a certain level by vibrating or flashing, so the sound recognition aids Frequent operation makes deaf people feel tired
[0006] In addition, the existing sound identification auxiliary devices can only reflect a small amount of attributes of external sounds, and the sound recognition ability is weak.
Moreover, the output prompt is also relatively simple, and the amount of information contained in the frequency and amplitude of the sound is too small
In addition, the output prompt is not intuitive, and deaf people need repeated practice to use it proficiently

Embodiment Construction

[0026] Some possible implementations of the present application are described below with reference to the accompanying drawings.

[0027] figure 1 The basic composition of the sound identification aid for the deaf according to one aspect of the application is shown in . The voice identification auxiliary device mainly includes a processing unit 1 and a sound collection unit 2 , a storage unit 3 , and a prompt output unit 4 respectively connected thereto.

[0028] The sound collection unit 2 is used to receive external sound, and transmit the external sound signal (for example in the form of A / D conversion data) to the processing unit 1 .

[0029] The sound collection unit 2 includes a microphone or an array composed of multiple microphones.

[0030] The processing unit 1 includes a sound recognition / processing MCU capable of recognizing sound signals from the sound collection unit 2, and processing and analyzing the sound signals to determine properties of the sound signals....

Abstract

The invention discloses an auxiliary device for sound distinguishing. The auxiliary device for sound distinguishing comprises a processing unit, and a sound collection unit, a storage unit and a prompt output unit which are connected with the processing unit, wherein the storage unit comprises a sound template library, and the sound template library comprises sound templates which define sound attributes meaningful for deaf users; the processing unit comprises a matching module used for the matching between an external sound signal collected by the sound collection unit and one of the sound templates in the sound template library; and the prompt output unit comprises a vibration element and a video signal generation element which are used for outputting output prompt signals corresponding to the sound templates in the sound template library. The auxiliary device for sound distinguishing provided by the invention has the advantage that the overall performance is improved.

Description

technical field [0001] The present application relates to a sound recognition auxiliary device that provides meaningful external sound prompts for the deaf. Background technique [0002] For deaf people, it is important to acquire cues for certain sounds. For example, the sound of a car horn or sudden noise may contain danger signals. Therefore, it is beneficial for the deaf to interpret the sound and give appropriate prompts to the deaf through vibration or video signals. [0003] A sound identification auxiliary device in the prior art collects, filters and amplifies external sound signals, and then outputs vibration prompts. Another kind of sound recognition auxiliary device uses a single-chip microcomputer to judge the direction of the car's whistle, and prompts different directions of the whistled vehicle through different vibration frequencies and times. There is also a sound identification auxiliary device that converts external sounds into vibration signals and op...
