Detailed Description
The invention will be further explained by means of specific embodiments with reference to the drawings.
Embodiment 1, as shown in fig. 1, a method for controlling an interactive live classroom by using voice commands is used for an internet-based live classroom and comprises a voice initiating end and an executed end. The execution main body of the voice interaction method is a voice initiating end and an executed end, and the voice initiating end and the executed end are a teacher use terminal and a student use terminal. When a teacher wants to control a terminal of the teacher through voice, the voice initiating terminal and the executed terminal are both teacher use terminals; when a teacher wants to control students to use a terminal through voice, the voice initiating end is the teacher use terminal, and the executed end is the student use terminal; when a student needs to simply feed back a teacher, the voice initiating end is a student use terminal, and the executed end is a teacher use terminal; when the student needs to control own equipment through voice, the voice initiating end and the executed end are both student use terminals.
As shown in fig. 2, the method of the present invention comprises the steps of:
s1, the voice initiating terminal receives the external voice and decodes and interprets it. Firstly, an external voice is recognized through a voice recognition module and then transmitted to the voice initiating end, and the compiled voice characters are generated after analysis and compilation. The voice recognition module is used for recognizing the whole language, and the preferred default language in the scheme is Chinese Putonghua.
And S2, generating an interaction control command according to the decoded and translated compiled phonetic characters. The compiled phonetic characters are stored in a terminal (preferably a computer) processor of the voice initiating terminal, and the interactive control instruction is generated by a voice recognition module program.
And S3, issuing the interaction control instruction to the corresponding executed end for execution.
Based on voice recognition, the compiled voice characters are obtained after parsing and compiling, an interaction control command is generated, and finally the command is issued to the corresponding executed end to execute control, so that the corresponding executed end completes corresponding actions, the efficiency of interactive live broadcast class administration is improved, and the interactive experience of a class is further improved.
Example 2
Based on embodiment 1, the difference from the embodiment is that:
as shown in fig. 3, the step S1 includes:
s1.1a, the voice signal initiating end receives the external voice through a radio device and converts the external voice into a second voice signal which can be recognized by the voice initiating end.
S1.2a, the speech signal obtains the compiled speech character through decoding and translation.
Furthermore, the products of voice input are more and more popular nowadays, and the application scenes of voice input are more and more common. However, the speech input always affects the recognition rate due to noise interference in the application scene, and how to eliminate the scene noise and improve the speech recognition rate is a very critical problem. As shown in fig. 4, the step S1 includes: and receiving the external voice and performing noise filtration through a voice recognition module to generate a first voice signal.
The sound collection is carried out in five levels, namely, a loud language, a normal language, a small language, a fine language and a whisper language, thresholds of various technical parameters of amplitude, frequency, wavelength, sound, tone, timbre, sound source vector and the like of sound of each level are set, a sound spectrum of a quiet environment authority user is generated, and the system senses and memorizes the sound spectrum of the authority user. After the sound spectrum under the quiet environment is generated, the system automatically synthesizes the sound spectrum of the authority user with various application scene noises collected in advance to generate the sound spectrum of the authority user under the noise background, senses and memorizes the sound spectrum of the authority user under the noise background, and automatically trains the sensitivity of voice input for detecting, identifying and discriminating the sound spectrum of the authority user under the actual application scene.
The embodiment can avoid the voice equipment from executing the voice instruction in the surrounding environment mistakenly, thereby improving the voice interaction efficiency and improving the experience of the user in using the voice equipment.
As shown in fig. 4, the step S1 includes:
s1.1b, receiving the external voice, performing noise filtering through a voice recognition module, and converting the external voice into a third voice signal which can be recognized by a voice initiating end;
s1.2b, the speech signal obtains the compiled speech character through decoding and translation.
Wherein the step S1.2b comprises:
judging whether the compiled voice characters comprise voice initiating terminal identity authority information, corresponding executed terminal identity information and command information or not, and if the compiled voice characters are all possessed by the voice initiating terminal identity authority information, obtaining the compiled voice characters through decoding and translation; and if the judgment result shows that the information is not completely provided, generating first feedback information for error prompt. For example, the language teacher sends a command of opening the student end MATLAB software, the language teacher does not control the authority of the student end MATLAB software switch, and after judging that the authority is not controlled, the language teacher returns the first feedback information of 'no authority to perform the operation'.
Example 3
Based on embodiment 2, the difference from embodiment 2 is that:
the compiled phonetic characters comprise identity authority information of a phonetic initiating terminal, corresponding identity information of the executed terminal and command information.
As shown in fig. 5 to 6, the step S2 includes:
and S2.1, acquiring and storing the compiled phonetic characters.
And S2.2, re-compiling according to the compiled voice characters to generate the interaction control instruction.
Said step S2.2 comprises:
s2.21, extracting the compiled voice characters, judging whether the voice initiating terminal has the authority to execute the command on the corresponding executed terminal or not according to the identity authority information of the voice initiating terminal, the corresponding executed terminal identity information and the command information, and if the judgment result is that the voice initiating terminal has the authority, performing the next step; and if the judgment result is that no authority exists, generating second feedback information refusing to be executed.
Wherein the second feedback information includes reason information for rejection.
And S2.22, generating the interactive control instruction.
Example 4
Based on embodiment 1, the difference from embodiment 1 is that:
as shown in fig. 7, the step S3 is followed by:
and S4, judging whether the received interaction control instruction is successfully executed, and if not, generating third feedback information of failed execution to the voice initiating terminal.
When the voice initiating terminal receives the third feedback information containing the execution failure, the voice initiating terminal can issue the voice command again and control the corresponding executed terminal again.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and do not limit the spirit and scope of the present invention. Various modifications and improvements of the technical solutions of the present invention may be made by those skilled in the art without departing from the design concept of the present invention, and the technical contents of the present invention are all described in the claims.
