The invention is based on historical big data, namely historical dictation data of a plurality of users, and statistically analyzes (such as classification and weighting), sets a difficulty standard according to a statistical result, and controls the reading speed according to the difficulty standard. The pertinence is stronger, and the experience is better for the user side.
As shown in fig. 2, which is a schematic diagram of another embodiment of a dictation control method in an embodiment of the present invention, the method may include:
201. and acquiring writing video information of a plurality of users when using the unified teaching material to listen and write.
202. And obtaining the average writing duration, the average completion rate and the average correct rate of the multiple users according to the writing video information of the multiple users when using the unified teaching material for dictation.
203. And classifying the dictation contents in the unified teaching material according to the average writing duration, the average completion rate and the average accuracy of the multiple users to obtain classification results, wherein the classification results comprise dictation contents with difficult grades and dictation contents with non-difficult grades.
It should be noted that, in the embodiment of the present invention, the step 201-203 is similar to the step 101-103 in the embodiment shown in fig. 1, and is not described herein again.
204. And responding to the selection operation of the user on the second dictation content with the first speech speed, and reporting and reading the second dictation content, wherein the second dictation content belongs to the dictation content with the difficulty level.
In the embodiment of the present invention, after the terminal device obtains the classification result, on a display screen of the terminal device, dictation contents at a first speech rate, that is, dictation contents at a difficulty level, may be included; dictation content at a second speech rate, i.e., dictation content at a non-difficult level; optionally, the method may further include dictation content at a third speech rate, that is, dictation content at a normal level; wherein the third speech rate is greater than the first speech rate and less than the second speech rate.
For example, if a user wants to practice some simple dictation contents today, a user may select a non-difficult-level dictation content for dictation on the terminal device, if the user wants to practice some slightly difficult dictation contents, a normal-level dictation content may be selected for dictation on the terminal device, and if the user wants to practice some difficult-level dictation contents, a difficult-level dictation content may be selected for dictation on the terminal device. The time corresponding to different types of dictation content may also be set by the terminal device, for example: after the dictation contents with the difficulty level are dictating for half an hour, the user can be reminded to have a rest to perform dictation contents with the non-difficulty level or perform dictation contents with the normal level. Or the user may select dictation time, or select a dictation unit, or select the number of dictated words, etc. when selecting dictation content of a dictation type, which is not limited in the embodiment of the present invention. That is, the user can flexibly select the content to be dictated according to the actual requirements of the user, and the user experience is improved.
Optionally, the dictation content may also be displayed by a conventional directory, that is, according to a conventional reading sequence, if the read dictation content belongs to the dictation content of the difficulty level, reading at the first speech speed may be performed; if the reported dictation contents belong to the dictation contents with non-difficult levels, the reporting can be carried out at a second speed; alternatively, if the reported dictation belongs to normal-grade dictation, the reading may be performed at a third speech rate.
205. When the accuracy rate of the first target dictation content is larger than a specific threshold value, adjusting the first speech rate of the first target dictation content to a second speech rate, wherein the second dictation content comprises the first target dictation content.
Illustratively, when a first target dictation content, such as "fruit", is spoken at a first speech rate, which itself sets dictation 3 times, but 2-3 dictations are accurate, the "fruit" may be classified as either a normal grade of dictation content or a non-difficult grade of dictation content, i.e., the first speech rate of "fruit" is updated to a third speech rate or the second speech rate for reading.
