The mandarin pronunciation rectifier
Technical field
The utility model relates to a kind of mandarin pronunciation rectifier, belongs to Chinese literature technical field.
Background technology
Popularizing Beijing pronunciation is the permanent state basic policy of China, and along with national development, overseas Chinese's dealing is increasing; External foreign student also increases year by year; Hong Kong, Macao, Taiwan are entered a country frequent, and it is very lack of standardization that voice seem, even comprise the performer's performance overseas of media broadcast, TV programme; How frequent generation with a mixed accent makes them improve the level that speaks standard Chinese pronunciation through self-study and seems very important.
Summary of the invention
In order to address the above problem; The purpose of the utility model is to provide a kind of mandarin pronunciation rectifier, is through on LCD, accessing each Chinese character one by one, and the user compares the mandarin standard pronunciation that ROM (read-only memory) in its pronunciation and its device stores; Word is practised repeatedly one by one; Can also compare through acknowledgement key, look at much gaps, so that further exercise.
The technical scheme that its technology that solves the utility model is adopted is: the mandarin pronunciation rectifier, it is made up of casing, circuit board, loudspeaker, LCD, receiver, character input keyboard, literal supervisory keyboard, standard sound operating key, exercise sound operating key, sensitivity control knob, acknowledgement key, power switch.At the casing internal fixation circuit board is arranged, on the panel of casing, be fixed with loudspeaker from top to bottom respectively, loudspeaker is connected with the analog amplify circuit of circuit board; Be fixed with LCD, LCD is connected with word processor with the microprocessor of circuit board respectively; Be fixed with character input keyboard, literal supervisory keyboard, character input keyboard, literal supervisory keyboard all are connected with word processor; Be fixed with receiver, receiver is connected with the D/A converting circuit of circuit board; Be fixed with standard sound operating key, exercise sound operating key, sensitivity control knob, acknowledgement key, standard sound operating key, exercise sound operating key, sensitivity control knob, acknowledgement key all are connected with the microprocessor of circuit board; Be fixed with power switch, power switch is connected with circuit board, power supply respectively.Described circuit board is made up of word processor, microprocessor, storer, dynamic storage, ROM (read-only memory), clock circuit, analog amplify circuit, D/A converting circuit.Analog amplify circuit is connected with microprocessor through D/A converting circuit; Word processor is connected with microprocessor through storer; Dynamic storage, ROM (read-only memory), clock circuit, D/A converting circuit are connected with microprocessor respectively.
The beneficial effect of the utility model is: repeating and relatively, can improve the level that standard pronunciation is spoken Mandarin rapidly through word one by one.This apparatus structure is simple, adopts lithium battery power supply, and is small and exquisite, easy to use, and external, overseas Chinese foreign student who is particularly suitable in the school and south and Minority College Students oneself practice assiduously and use when improving Chinese proficiency.The pronunciation of this device input and the comparative result of mandarin standard pronunciation show with percentage, can be used for saying that in the campus standard pronunciation uses when speaking Mandarin match.In addition, the character input keyboard of this device is identical with the standard Chinese spelling input keyboard, can be used for practising separately input Chinese character or study use.

Embodiment
See also Fig. 1, Fig. 2; The mandarin pronunciation rectifier, it is made up of casing, circuit board, loudspeaker, LCD, receiver, character input keyboard, literal supervisory keyboard, standard sound operating key, exercise sound operating key, sensitivity control knob, acknowledgement key, power switch.At casing 1 internal fixation circuit board 2 is arranged, on the panel of casing 1, be fixed with loudspeaker 3 from top to bottom respectively, loudspeaker 3 is connected with the analog amplify circuit of circuit board 2; Be fixed with LCD 4, LCD 4 is connected with word processor with the microprocessor of circuit board 2 respectively; Be fixed with character input keyboard 6, literal supervisory keyboard 7, character input keyboard 6, literal supervisory keyboard 7 all are connected with word processor; Be fixed with receiver 5, receiver 5 is connected with the D/A converting circuit of circuit board 2; Be fixed with standard sound operating key 8, exercise sound operating key 9, sensitivity control knob 10, acknowledgement key 11, standard sound operating key 8, exercise sound operating key 9, sensitivity control knob 10, acknowledgement key 11 all are connected with the microprocessor of circuit board 2; Be fixed with power switch 12, power switch 12 is connected with circuit board 2, power supply respectively.Described circuit board 2 is made up of word processor, microprocessor, storer, dynamic storage, ROM (read-only memory), clock circuit, analog amplify circuit, D/A converting circuit.Analog amplify circuit is connected with microprocessor through D/A converting circuit; Word processor is connected with microprocessor through storer; Dynamic storage, ROM (read-only memory), clock circuit, D/A converting circuit are connected with microprocessor respectively.
Method of application: turn on the power switch after 12 and can want the Chinese character practising pronouncing through literal supervisory keyboard 7, character input keyboard 6 inputs; Can be after Chinese character shows by standard sound operating key 8 pronunciation repeatedly automatically, through by its+,-key can adjust each pronunciation automatically 1~10 time.When wanting imitation exercise pronunciation; Press exercise sound operating key 9; Can carry out pronunciation exercises facing to receiver 5, when thinking satisfied, can press exercise sound operating key 9 once more, the last pronunciation that this moment, dynamic storage deposited record in; The beginning pronunciation repeatedly automatically after 5 seconds of delaying time, through by its+,-key can adjust each pronunciation automatically 1~10 time.When needs look at that oneself pronunciation and RP have much gaps; Can press acknowledgement key 11; The pronunciation of its exercise will be compared with the RP of ROM (read-only memory) storage, draw an approximate number percent digital display and be shown in LCD 4 following centre, can adjust two kinds of pronunciations degree of approximation relatively through adjustment sensitivity control knob 10; Relatively accurate more of more past dextrorotation, more past left-handed comparison coarse more.
