Description
Technical field
The utility model relates to a kind of instructional device, particularly a kind of English-teaching aid.
Background technology
When carrying out English teaching, English teacher is in order to improve teaching efficiency, increase classroom atmosphere, usually needing to carry other teaching materials (as picture, card etc.) comes with student interactive, as allowed student read word with the alphabetical card with word, or student is allowed to carry out Chinese to English or English to Chinese with card.But no matter read word or Chinese to English, be all the pronunciation of English whether standard being judged student by teacher mostly, this error in judgement is comparatively large, does not still improve the English level of student; In the process of Chinese to English or English to Chinese, there is no timing in addition, reaction capacity and the Listening Ability of Ethnic of student can not be improved.
Utility model content
It is overcome the deficiencies in the prior art and provide a kind of English-teaching aid that can improve teaching efficiency and classroom atmosphere that the utility model obtains object, thus the reaction capacity of raising student, Listening Ability of Ethnic and pronunciation of English level.
The technical scheme that the utility model solves is: a kind of English-teaching aid, comprises base, support and Graphic Panel, and described support is provided with automatically controlled box body, the voice control circuit being provided with controller in shown automatically controlled box body and being connected with controller; Described voice control circuit comprises outside load module, sound identification module, voice storage module and voice output module; The output terminal of described outside load module connects sound identification module, and the output terminal of sound identification module connects voice output module; Described sound identification module and voice storage module connection control device respectively; Described Graphic Panel is provided with display module, the output terminal of described display module connection control device.
Further, described Graphic Panel is also provided with timing module and hummer, described timing module is connected with controller respectively with hummer.
Further, described timing module and display module are charactron, and timing module is used for displaying time countdown, and display module is used for display " √ " or "×".
Further, described outside load module is microphone.
Further, described voice output module is loudspeaker.
Further, the lower end of described timing module is provided with button, for setting-up time; Described button is connected with the input end of controller.
Further, described button comprises up key, down key, acknowledgement key and beginning key.
Further, described controller is embedded chip.
Further, described Graphic Panel is board material.
The beneficial effects of the utility model:
(1) by arranging voice control circuit, can judge that whether the pronunciation of English of student is accurate, thus improving the pronunciation of English level of student;
(2) by design timing module and hummer, can carry out rapidly between English word and Chinese conversion memory at short notice by training student, thus improve reaction capacity and the Listening Ability of Ethnic of student.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the circuit structure block diagram of the utility model embodiment.
Embodiment
As depicted in figs. 1 and 2: a kind of English-teaching aid, comprise base 1, support 2 and Graphic Panel 3, support 2 is installed on base 1, and Graphic Panel 3 is installed on support 2.Support 2 is provided with automatically controlled box body 4, the voice control circuit being provided with controller in automatically controlled box body 4 and being connected with controller; Voice control circuit comprises microphone, sound identification module, voice storage module and loudspeaker; The output terminal of microphone connects sound identification module, and the output terminal of sound identification module connects loudspeaker; Sound identification module and voice storage module connection control device respectively.Graphic Panel 3 is provided with display module 5, the output terminal of display module 5 connection control device, and display module 5 is charactron, for display " √ " or "×".
In the present embodiment, controller can select the high-grade single chip computer AT mega8 of the new A VR of Low-Power CMOS explained hereafter; Microphone is used for the voice signal of reception to be converted to analog voice signal; The optional voice recognition chip LD3320 of sound identification module, the signal input part of voice recognition chip LD3320 is connected with microphone, and the signal output part of voice recognition chip LD3320 is connected with the I/O mouth of ATmega8 single-chip microcomputer; Voice recognition chip LD3320 is used for the voice signal that transmitted by microphone to carry out the phonetic order information processed in rear voice storage module and to compare coupling, and becomes electric signal to be exported by loudspeaker the results conversion of coupling; Voice storage module can select high-performance CMOS Static RAM memories CY62256, for storing word English Phonetics command information, normally stores the standard English phonetic order information sent by American or Englishman.When student reads word, if when pronunciation differs larger with the voice of script word, namely sound identification module cannot be compared when mating with the phonetic order information in voice storage module, then display module 5 shows "×", represent that the cacoepy of this student is true; When sound identification module can compare with the phonetic order information in voice storage module mate time, then display module 5 shows " √ ", again sends the demonstration of correct word pronunciation by loudspeaker simultaneously, thus improve the pronunciation of English level of student.
Graphic Panel 3 is also provided with timing module 6 and hummer 7, timing module 6 is connected with the output terminal of controller respectively with hummer 7.Timing module 6 is charactron, and for displaying time countdown, the lower end of timing module 6 is provided with button 8, for setting-up time; Button 8 is connected with the input end of controller.Button 8 comprises up key, down key, acknowledgement key and beginning key, and up key is used for carrying out forward setting to the time, and down key is used for passing setting backward to the time, and acknowledgement key is for determining the final set time, and beginning key is used for timing to start.Such as: being a teacher allows student carry out English to Chinese with card, first power-on, and now time default value is 8s, press up key and can carry out 1 ~ 7s setting, press down key and can carry out 9 ~ 15s setting.The time of carrying out English to Chinese to each word as set student is 5s, press and start key and carry out countdown and start, after countdown terminates, hummer 7 buzzing is pointed out, teacher can change a card and proceed countdown, now do not need to press beginning key, timing module carries out countdown next time automatically, and teacher only needs fast quick change card.
Graphic Panel 3 in the present embodiment is board material, both can give lessons with special writing pen, can carry out interesting English game again by magnetic fixed card or picture, thus helps student to improve vocabulary memorization power, and then improves teaching efficiency and classroom atmosphere.
