Description

A Piano Teaching Auxiliary Device Suitable for Hearing Impaired Students

technical field

The invention relates to the field of teaching aids, in particular to a piano teaching auxiliary device suitable for hearing-impaired students.

Background technique

As we all know, hearing impairment refers to the occurrence of organic or functional abnormalities in the nerve centers at all levels of sound transmission, sensory sound and comprehensive analysis of sound in the auditory system, resulting in varying degrees of hearing loss, which is commonly called deafness. Only severe hearing loss is called deafness, which is characterized by the inability to hear any speech in both ears of the patient, and those whose hearing loss does not reach this severity are called hearing loss.

Although the country has established schools specially for the education of hearing-impaired students, there are no targeted teaching aids to assist teachers in teaching when hearing-impaired students learn music knowledge, especially for hearing-impaired students who are interested in piano. Operation and use cannot be normally taught to hearing-impaired students, and there is an urgent need for a piano teaching aid to help teachers and hearing-impaired students learn and communicate piano knowledge.

Further, the display module is a touch screen display module.

Compared with prior art, the beneficial effect of the present invention is:

The invention can realize the two-way communication between the hearing-impaired students and the piano teacher through the speech recognition module, camera, speech synthesis module, speech-to-text conversion module, display and wireless communication module, the communication effect is good, and the market prospect of wide application is obtained.

Description of drawings

Fig. 1 is a functional block diagram of a piano teaching auxiliary device suitable for hearing-impaired students provided by the present invention.

detailed description

A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in Figure 1, a kind of piano teaching auxiliary device that is applicable to the hearing-impaired student that the embodiment of the present invention provides, comprises: voice recognition module, A/D conversion module, voice-to-text conversion module, processor module, camera module, storage Module, keyboard module, display module, wireless communication module, D/A conversion module, speech synthesis module and loudspeaker module; Described speech recognition module is connected with voice-to-text conversion module by A/D conversion module, and voice-to-text conversion module passes D/ The A conversion module is connected with the speech synthesis module, the speech synthesis module is connected with the loudspeaker module, and the speech-to-text conversion module, the camera module, the storage module, the keyboard module, the display module and the wireless communication module are respectively connected with the processor module.

How to use: This device is similar to a smart phone. The processor module can be the CPU of the mobile phone. It receives the teacher's explanation sound through the microphone, and converts the teacher's explanation sound into a sound analog signal through the voice recognition module. The sound analog signal passes through the A/D conversion module. It is converted into a sound digital signal, and the sound digital signal is converted into an alphanumeric signal by a voice-to-text conversion module. After being processed by a processor module, the alphanumeric signal is displayed on the display screen through a display module. Students with hearing impairment can see the teacher's explanation through the display screen. At the same time, the teacher's demonstration image is obtained through the camera, and converted into an image digital signal through the camera module. After the image digital signal is processed by the processor module, it is transmitted through the wireless transmission module in the wireless communication module, and then transmitted through the wireless communication module. After being received by the wireless receiving module, it is processed by the processing module and displayed on the display module and the display. The hearing-impaired students can watch the teacher's demonstration action while reading the teacher's explanation content, so as to realize the explanation and communication between the teacher and the students.

When students have questions and need to consult the teacher, they input text through the keyboard, and convert the text into alphanumeric signals through the keyboard module. The /A conversion module converts it into a voice analog signal, and the voice analog signal is synthesized by the speech synthesis module and then played through the player module and the player. The teacher can hear the problems of the hearing-impaired students and realize the communication between the students and the teacher.

According to the distance of the teaching, when the distance is long, the teacher and the students each hold an auxiliary device to communicate, and when the distance is short, the students can communicate with the teacher by holding one.

The invention can realize the communication between the teacher and the hearing-impaired students, so that the teacher can use normal voice to communicate with the hearing-impaired students in piano learning.

Further, the speech synthesis module includes a SYN6658 Chinese speech synthesis chip and a power amplification module, the SYN6658 Chinese speech synthesis chip is connected to the power amplification module, the SYN6658 Chinese speech synthesis chip is connected to the D/A conversion module, and the power amplification module is connected to the speaker module .

The SYN6658 Chinese speech synthesis chip can realize text intelligent analysis and processing capabilities, polyphonic word processing and Chinese surname processing capabilities, and has clear, natural and accurate Chinese speech synthesis effects.

Further, the speech recognition module adopts LD3320 speech recognition chip.

The LD3320 voice recognition chip integrates a fast and stable optimization algorithm, which can complete the non-specific voice recognition without the user's prior training and recording, and the recognition accuracy is high.

Further, the storage module adopts 64Mbit SPI-Flash memory.

64Mbit SPI-Flash memory, large storage capacity, fast data operation.

Further, the display module is a touch screen display module.

The touch screen display module facilitates the input of characters, makes the display screen larger and has a beautiful appearance.

The above disclosures are only a few specific embodiments of the present invention, however, the embodiments of the present invention are not limited thereto, and any changes conceivable by those skilled in the art shall fall within the protection scope of the present invention.
