Quick answer method and its system based on speech recognitionTechnical field
The present invention relates to educational training technical fields, and in particular to a kind of quick answer method based on speech recognition and itsSystem.
Background technique
Currently, many education and training organization, including school are all periodically to be examined by paper to student, in order to correctPaper is convenient, and every part of paper generally can all have corresponding answering card.It examines each time, school requires manually to update typesettingPaper, the corresponding answering card of production, finally also want group signature.
In recent years, as the continuous upgrading of information technology and IT application in education sector develops, computer and artificial intelligence technology areGradually it is applied in daily education and instruction Activities.
Such as in Chinese patent literature CN107680019A, a kind of implementation method of Examination Scheme is disclosed, comprising: reallyFixed current examination question to be pushed, and pushed to examinee；Obtain the answering information that examinee is directed to the current examination question；Based on default examinationTopic relational model tests and assesses to the answering information, to determine lower one of examination question；Lower one of examination question is updated to be used as and is worked asPreceding examination question, and execution push operation is returned, until determining examination result.It further include having to obtain examinee for the current examination questionScript information in answering information include: receive the examinee for the script voice of the current examination question feedback orScript text；The script voice or script text are matched with model answer, to determine that examination question is answeredCase matching degree, as script information.
But above-mentioned technical proposal, which answers for voice, can not carry out quick response, affect student and answer speed.
Summary of the invention
The quick answer method based on speech recognition that the problem to be solved in the present invention is to provide a kind of.
In order to solve the above technical problems, the scheme that the present invention uses is: should the quick answer method packet based on speech recognitionInclude following steps:
(1) student issues the instruction for starting to carry out examination question answer, after receiving instruction, examination question is extracted from database and by suitableSequence layout shows student to answer；
(2) voice that student answers for current display examination question is received to answer result；
(3) speech recognition is carried out to the voice of current examination question result of answering, and voice result of answering is converted to textAnswer as current examination question is saved；
(4) next topic is jumped to, and shows student to answer as current examination question next topic, is repeated step (2)(3).
By adopting the above technical scheme, using speech recognition technology, voice result of answering is converted to text as currentThe answer of examination question is saved, and speed is fast, improves efficiency；The uncertainty and error rate of direct Speech comparison are reduced,It is high to experience comfort level.
Preferably, in the step (2), after showing current examination question to student, while starting reception speech recognition and referring toIt enables, after student clicks next topic for current examination question, voice recognition instruction revocation.
When reading current examination question, it can answer at any time for current examination question, not influence speed of answering, meanwhile, it is learningAfter member clicks next topic, voice recognition instruction revocation avoids obscuring on examination question of answering.
Preferably, in the step (1), the examination question classification layout for showing student to answer, each type of examinationTopic individually grouping before each type of examination question accounting can start according to answer, carries out default production in an examination question extraction processRaw different ratio.
Preferably, in the step (3), identified voice answers after result is converted to text and is shown in answering for examination questionCase region, answer region can provide manual amendment, correct the false demonstration of voice conversion text, and can show outside answer regionConfirmation or revocation button, carry out selection click by student.
Click revocation button after, again to the voice of student answer result carry out speech recognition, if click confirmation, then notIt needs.
Preferably, it in the step (4), jumps to next topic and is realized in the form that displayed page slides, and slidedThe current examination question of dynamic operation is no longer shown, only shows student to answer as current examination question next topic；The page is slidingThe dynamic selected topic has upper cunning, downslide, left cunning, right sliding mode to realize, and any two sliding combination definition is used to realize last question underOne topic selection.
Page sliding, gives student's regular hour and looks back the examination question again, to be confirmed whether that answer is correct；Cunning is gone upCurrent examination question is no longer shown, only shows student to answer as current examination question next topic, it is bigger to give current examination questionThe visual field, avoid last question dispersion student attention.
Preferably, there is label button as the examination question that leaves a question open, the step to be done beside the examination question each currently shown(4) after, all examination question practices are finished, and are shown one time again again to the examination question that leaves a question open of student's label.
During practice, for answer do not think of for the moment come or uncertain answer it is whether correct in the case ofUnder, setting flag button is used as the examination question that leaves a question open, and it is subsequent that the examination question that leaves a question open of label is shown one time again again again, to provide student'sFinal result.
Preferably, further include thering is practice or examination result to show step, answer after all examination questions to student, it will be describedScript is matched with model answer, and to determine script matching degree, as script information, display is this time practicedOr total marks of the examination and save be uploaded to Background control terminal.
Preferably, in the step (3), correctness is Validationed Answer Key on one side while answer, just automatic is jumped if correctTurn next topic and carries out the step (4)；If incorrect, speech recognition result is just shown, correction result or manually select jumps toNext topic.
The present invention also provides a kind of quick answering system based on speech recognition includes:
Item database unit, for storing examination question；
Examination question display unit, from the examination question extracted in the item database unit in the examination question display unitIt shows for examinee's answer；
Voice recognition unit carries out speech recognition to the voice of current examination question result of answering, and the voice is answered resultThe answer that text is converted to as current examination question is saved；
Examination question jump-transfer unit jumps to next topic from current examination question, and next topic is showed student as current examination questionIt answers；
Answer unit as the result is shown answers after all examination questions to student, shows this answer achievement and save uploadTo Background control terminal.
Preferably, the voice recognition unit further includes having the identification module based on A.I, to voice answer result carry out languageSound identification.
Preferably, which further includes having answer authentication unit, for Validationing Answer Key correctness on one side while answer, ifIt is correct, examination question jump-transfer unit is fed back to, next topic is jumped automatically and carries out the step (4)；If incorrect, voice is just shownRecognition result, correction result or manually selects and jumps to next topic by examination question jump-transfer unit.
