Embodiment 1

[0018] refer to figure 1 , shows a flow chart of steps of a method for session segmentation according to Embodiment 1 of the present invention.

[0019] The session segmentation method of the present embodiment includes the following steps:

[0020] Step S102: Determine the session start point for the current session in the multimedia data.

[0021] Wherein, the multimedia data may be data including at least one of audio data and video data. The multimedia data contains at least one session, each session includes at least one sentence, and each session corresponds to a corresponding session start point.

[0022] The determination of the conversation start point can be realized by a person skilled in the art in an appropriate manner. For example, the multimedia data can be firstly subjected to speech recognition to recognize the text corresponding to each sentence (that is, each sentence), and the text also has time information at the same time. Such as timestamp. In this c...

Embodiment 2

[0043] refer to figure 2 , shows a flow chart of steps of a session segmentation method according to Embodiment 2 of the present invention.

[0044] The session segmentation method of the present embodiment includes the following steps:

[0045] Step S202: Perform speech detection on the multimedia data, and obtain sentence starting points of multiple sentences contained therein.

[0046] In this embodiment, multimedia data containing multiple (two or more) sentences is taken as an example, but those skilled in the art should understand that the solutions of the embodiments of the present invention are also applicable to multimedia data containing only one sentence.

[0047] Speech detection for multimedia data may be implemented by those skilled in the art in any appropriate manner, for example, an ASR (Automatic Speech Recognition, automatic speech recognition) manner, etc., which is not limited in this embodiment of the present invention.

[0048] By performing speech de...

Embodiment 3

[0086] refer to Figure 3A , shows a flow chart of steps of a method for session segmentation according to Embodiment 3 of the present invention.

[0087] This embodiment describes the session segmentation method provided by the embodiment of the present invention in the form of a specific example. In this specific example, one-to-one teaching is used as the scene, the multimedia data is in the form of video including audio, and the dialogue between the teacher and the students is in the form of conversation.

[0088] Based on this, the session segmentation method of the present embodiment includes the following steps:

[0089] Step S302: Determine the session start point for the session in the video, and detect the session end point of each session.

[0090] Initially, the first sentence spoken by the teacher in the video can be used as the starting point of the conversation, and the ending point of the conversation can be detected. After the session start point and sessio...

Abstract

The embodiment of the present invention discloses a session segmentation method, an electronic device, and a computer-readable medium, wherein the session segmentation method includes: determining a session start point for a current session in multimedia data; taking the session start point as a starting point, judging Whether there is a session satisfying the benchmark detection standard in the preset session interval, wherein the benchmark detection standard is used to indicate the detection rule used by the benchmark detection, and the detection rule is used to detect whether there is a complete session in the multimedia data in the preset session interval; If it exists, determine the candidate session end point of the current session according to the end point of the session that satisfies the benchmark detection standard; for the session between the determined session start point and the candidate session end point, perform at least one test according to the preset detection priority Auxiliary detection of the session end point at the level; determine the session end point of the current session according to the detection result of the auxiliary detection; perform session segmentation on the multimedia data according to the session start point and the session end point.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technologies, and in particular, to a session segmentation method, electronic equipment and computer-readable media. Background technique [0002] With the rise of the Internet, multimedia audio and video including one-on-one conversations appear in a large number of scenarios, such as one-on-one teaching scenarios, one-on-one interview scenarios, and so on. Using session segmentation technology to segment multimedia audio and video in these scenarios for subsequent data utilization and technical improvement has become one of the key technologies. [0003] Through the session segmentation technology, the session in the long segment of multimedia audio and video can be divided into effective session segments. Currently, the process of session segmentation is to detect the session start point and then detect the session end point, and perform session segmentation based on the detec...
