s107: judging whether the third voice data has the keyword or not;
s108: if yes, extracting courseware data including the keywords according to the keywords in the third voice data and outputting the data.
Acquiring all voice data comprises:
setting a preset range, and acquiring all voice data in the preset range.
The step of extracting courseware data including the keywords and outputting the data comprises the following steps:
and displaying the courseware data including the keywords through a display.
Specifically, the relation between the teaching system and the teacher provided by the invention is a one-to-many relation, namely the teaching system can be used by a plurality of teachers. In step S101, a user inputs the voice data in a normal state into the system through the voice input module one by one according to a prompt, and under the condition of voice input, it is necessary to ensure that there is and only the voice data of the user in a preset range of the voice input module, the voice input module acquires the voice data of the user when the user makes a normal sound, and determines whether there is and only one voice data of the user in the acquired voice data, if so, the input is completed, if voice data of multiple users are detected, the user is prompted to input again, and after the input is completed, the processing module stores the voice data of the user as the first voice data into the first storage module.
In step S102, a user connects to the system using an intelligent device, where the intelligent device includes a smart phone, a smart watch, a notebook computer, a desktop computer, and the like, and after the connection, the user sends courseware data to the system through the intelligent device, the receiving module receives the courseware data and forwards the courseware data to the processing module, the processing module analyzes whether the received courseware data is teaching data, if yes, the processing module stores the courseware data in the second storage module, and if not, the processing module deletes the courseware data.
In step S103, in order to facilitate the user to find the courseware data to be used at any time, after the user uses the intelligent device to connect to the system, the user uses the intelligent device to set the keywords in the selected courseware data, after the setting is completed, the processing module obtains the keywords set by the user and marks the keywords in the saved courseware data, and the processing module replaces the courseware data selected by the user in the second storage module with the courseware data marked with the keywords.
In step S104, when the system is used, the voice recording module acquires all the voice data in a preset range in real time and synchronously sends the acquired voice data to the processing module, and the processing module stores the voice data as second voice data in the first storage module, where the preset range at least covers a classroom in which the system is installed.
In step S105, the processing module extracts the second voice data and the first voice data, performs voiceprint comparison on the two and determines whether there is voice data consistent with a voiceprint of the first voice data in the second voice data, where the first storage device includes a plurality of first voice data of a plurality of users, the processing module compares the first voice data with all the second voice data one by one, the processing module performs multiple determinations, and if the processing module determines that the result is negative, performs the next determination; and if the processor module judges that the data is positive, stopping judging.
In step S106, when the processing module determines that the voiceprints are consistent, the processing module extracts a part of the voice data in the second voice data that is consistent with the voiceprint of the first voice data as third voice data, that is, in this step, the voice data of the user during class speaking is obtained.
In step S107, the processing module determines whether a keyword exists in the third speech data in real time.
In step S108, if the processing module determines that the third voice data includes a keyword, extracting courseware data including the keyword according to the keyword and displaying the courseware data through a display.
Example two
As shown in fig. 2, extracting and outputting courseware data including the keywords includes:
and if a plurality of courseware data comprise the keywords, calculating the times of the keywords in the courseware data, and preferentially extracting the courseware data with the most times of the keywords.
Specifically, the user divides the teaching data into a plurality of courseware data, the courseware data are all provided with independent keywords, different courseware data may comprise the same keywords, in order to improve the extraction accuracy of the invention, the processing module needs to filter the courseware data before outputting the courseware data, the processing module extracts all courseware data, the judging module judges whether the courseware data comprises the keywords one by one, after the judgment is finished, the processing module extracts all courseware data including the keywords, the counting module counts the times of the keywords appearing in the courseware data one by one, and sending the statistical result to the processing module, wherein the statistical result comprises the times of occurrence of the keywords and courseware data corresponding to the times, and the processing module preferentially extracts the courseware data with the maximum times of occurrence of the keywords and outputs the data.
EXAMPLE III
As shown in fig. 3, extracting and outputting courseware data including the keywords includes:
if the number of the keywords is more than one, the courseware data including all the keywords are extracted preferentially;
and if the courseware data comprising all the keywords does not exist, extracting the courseware data comprising the most keywords.
Specifically, the number of keywords set by the user may be multiple, and correspondingly, the third voice data may include a plurality of different keywords, the accuracy of extracting the courseware data can be further improved by combining the technical features of this embodiment with the technical features of the second embodiment, when the third voice data includes a plurality of different keywords, the processing module extracts all the courseware data, the determining module determines whether the courseware data includes the keywords one by one, if yes, the processing module determines whether the courseware data includes all the keywords, and if yes, the processing module preferentially extracts the courseware data including all the keywords and outputs the data; if not, the processing module extracts courseware data comprising the most keywords and outputs the data.
