When the playing audio frequency region 21 corresponding to the first lattice information includes the playing speed icon 23, the intelligent terminal 30 is controlled to play the playing audio frequency corresponding to the first lattice information according to the playing speed icon 23, so that the playing speed of the playing audio frequency is automatically controlled. Illustratively, the play speed icon 23 is used for the learner to determine the specific play speed of the dot code dictation paper 20; the data processor 14 intelligently stores the playing speed icons 23 corresponding to all playing audios on the page information according to the page information of the dot matrix dictation pages, when two dot matrix dictation papers 20 correspond to the same playing audios, but the page information of the two dot matrix dictation papers 20 is different, and one page information corresponds to one playing speed icon 23, so that the learning requirements of the learner at different stages can be met, and the intelligent degree is improved. Illustratively, the playing speed icon 23 is used for the learner to determine a specific playing speed of the dot matrix code dictation paper 20, and the data processor 14 identifies the playing speed icon 23 to determine a playing speed of the playing audio according to the playing speed icon 23, control the intelligent terminal 30 to play the playing audio corresponding to the first dot matrix information according to the playing speed icon 23, so that the learning requirements of the learner at different stages can be met, and the intelligence degree can be improved.

As an embodiment, after determining whether the playing audio region corresponding to the first lattice information includes the playing speed icon, the data processor is further configured to query the historical playing information of the playing audio corresponding to the first lattice information when the playing audio region corresponding to the first lattice information does not include the playing speed icon 23. And determining the target playing speed according to the historical playing speed in the historical playing information.

The historical playing information is information corresponding to the first lattice information when the playing audio is played. The history play speed is a speed at which the audio play is played.

Specifically, historical playing information of dictation corresponding to the first dot matrix information is stored in a ratio memory in advance to form historical playing information; and stores the playing audio corresponding to the first dot matrix information in association with the historical playing information in the pen memory 17 for subsequent searching. It can be understood that if the playing audio corresponding to the first lattice information is not played, there is no corresponding history playing information; if the playing audio corresponding to the first lattice information is played, recording information such as historical playing speed and the like during playing to form historical playing information. In this embodiment, if the played audio region 21 corresponding to the first lattice information does not include the playing speed icon 23, historical playing information of the played audio corresponding to the first lattice information is queried, so as to automatically determine the target playing speed.

As an embodiment, determining the target play speed from the historical play speeds in the historical play information includes:

and the data processor is also used for acquiring a target time interval between the latest historical playing time and the current time based on the historical playing information. And judging whether the target time interval is greater than the preset interval duration or not. And if the target time interval is greater than the preset interval duration, determining the standard playing speed as the target playing speed. And if the target time interval is not more than the preset interval duration, determining the historical playing speed corresponding to the latest historical playing time as the target playing speed.

The historical playing time is the time of playing the audio each time before the current time. Illustratively, the historical playing time may be x years, x months and x days, and 11-point 20-point playing; playing at 11 points and 40 points in x years, x months and x days; x month x day x year, 21 points and 20 points. The historical play speed is the speed at which the audio is played each time. The current time refers to the current time of the dot matrix pen 10; the target time interval refers to a time difference between the history play time closest to the current time and the current time. The preset interval duration is a preset time interval, and may be, for example, 1 minute. In this embodiment, the preset interval duration is subtracted from the target time interval to obtain a duration difference, and when the duration difference is greater than 0, the target time interval is greater than the preset interval duration; otherwise, when the time length difference is larger than 0, the target time interval is larger than the preset interval time length.

In this embodiment, the data processor queries the historical playing information to obtain the latest historical playing time, and subtracts the historical playing time closest to the current time from the current time to obtain the target time interval. Although there is historical playing information in the dictation audio corresponding to the first lattice information, since the target time interval is longer than the preset interval duration, the learner may perform different learning stages to determine the preset standard playing speed as the target playing speed, so as to automatically determine the playing speed. When the target time interval is longer than the preset interval duration, determining the historical playing speed corresponding to the historical playing time closest to the current time as the target playing speed corresponding to the first lattice information, so that the learning personnel can listen and write conveniently, and the operation of the learning personnel is reduced.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
