The first embodiment provided by the present disclosure, that is, an embodiment of a method for processing meeting information.
The embodiments of the present disclosure will be described in detail below with reference to fig. 1 and 2.
The method of the embodiment of the present disclosure is applied to a virtual reality headset, as shown in fig. 1, the virtual reality headset includes: the device comprises an audio acquisition module, a video acquisition module, a wireless communication module and a display module. The method comprises the following steps:
and S101, acquiring first audio information of a speaker in the current conference site by using the audio acquisition module.
The audio acquisition module is generally used for acquiring the live audio information of the current conference site to be used as the first audio information. However, when the conference site environment is complicated, the site audio information may include background noise in addition to the first audio information. Optionally, the obtaining, by using the audio acquisition module, first audio information of a speaker in a current conference site includes:
and S101-1, acquiring the on-site audio information of the conference site by using the audio acquisition module.
And S101-2, performing noise filtering processing on the live audio information to acquire first audio information of the speaker.
The embodiment of the disclosure adopts the preset filter to carry out noise filtering processing on the field audio information, so that the rising edge and the falling edge of the sudden change of the pulse are gentle, and the attenuation of the frequency outside the frequency band is accelerated. The first audio information obtained after the noise filtering treatment improves the accuracy of converting the audio into the corresponding characters.
And step S102, analyzing the first audio information to generate corresponding first character information.
The process of converting the audio information into the text information is not described in detail in this embodiment, and may be implemented by referring to various implementations in the prior art.
Step S103, acquiring first display information associated with the current conference.
The first display information includes first display images arranged in sequence. For example, the first display information includes video information constituted by one frame of continuously captured image and presentation information constituted by one frame of non-continuous presentation image.
In view of the above steps, the embodiments of the present disclosure provide two application scenarios.
Scene one:
mainly for video information.
The method for acquiring the first display information associated with the current conference comprises the following steps:
and S103-11, acquiring live-action video information of a conference site by using the video acquisition module as the first display information.
Scene two:

The participant characteristic information is unique information that distinguishes the participant from other persons. Such as a name or job number or certificate number.
The audio feature information is also the unique audio information that distinguishes the participant from other persons.
The audio feature information set is set information that is collected and stored in advance.
Further, for step S102, the analyzing the first audio information to generate corresponding first text information includes the following specific steps:
and step S102-1, performing audio characteristic analysis on the first audio information to acquire second audio information and second audio characteristic information of a second speaker behind the first speaker.
Firstly, the audio information of different speakers in the first audio information is separated, the second audio information of the latter speaker (i.e. the second speaker) is obtained, and the second audio feature information is extracted from the second audio information.
And S102-2, matching the second audio characteristic information with the audio characteristic information in the audio characteristic information set, acquiring participant characteristic information corresponding to the matched audio characteristic information, and using the participant characteristic information as second speaker characteristic information.
And S102-3, analyzing the second audio information to generate corresponding second character information.
And S102-4, generating first text information before adding the second speaker characteristic information to the second text information.
And second speaker characteristic information is added in front of the second text information, so that people wearing the virtual reality head-mounted equipment can browse the text information conveniently, and specific speakers corresponding to each sentence can be distinguished when a conference summary is generated automatically.
In order to improve the security of the conference, optionally, before the receiving, by using the wireless communication module, the audio feature information sets of the participants, the method further includes the following steps:
and S100-01, acquiring conference participation report audio information by using an audio acquisition module of the virtual reality headset within a preset report time range.
The participant reports the audio information, namely the participant sends the reported audio information through the audio acquisition module.
And S100-02, sending the participating report audio information by using the wireless communication module.
And S100-03, receiving report confirmation information responding to the audio information of the participating reports, and opening the display module based on the report confirmation information.
The steps can prevent irrelevant personnel from randomly entering the conference, and the safety and the reliability of the conference are improved.
Optionally, the method further includes the following steps:
and S106, storing the first character information and generating a conference summary.
The conference summary is automatically generated, so that the time for recording notes by the participants is reduced, and more energy can be concentrated in the conference.
