Detailed Description
The above and other objects, advantages and features of the present application will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.
Besides the dual-recording function in the related APP is to achieve the dual-recording normal compliance by prohibiting the user from using the earphone, a scheme using the WebRTC technology is also provided, and the dual-recording in the earphone mode can be realized. WebRTC, the name of which is abbreviated from Web Real-Time Communication (English), is an API that supports Web browsers for Real-Time voice conversations or video conversations. It was sourced at 1 st 6/2011 and was incorporated into the W3C recommendation of the world wide web consortium under the support of Google, mozilla, opera.
Based on the open-source WebRTC technology, firstly, a set of back-end services such as a signaling server, a streaming media server, a streaming recording service and the like needs to be established. Then, the front end needs to integrate the SDK of the corresponding platform, and performs an interaction with the service through the SDK. The current mainstream solution is based on the concept of a room, i.e. one room is created by one double recording, then all audio and video sources are used as a "member" of the room, and then a "god view" program exists in the room, and he "records" all what happens in real time in the room (i.e. the audio and video recording). The scheme adopts a server-side recording mode, and audio sources and image sources in the double recording process, including TTS (risk prompt language) and other sound sources, are distributed in a room as a member, so that a user can perceive the sound sources even if wearing earphones. Moreover, the scheme needs a large number of deep developers particularly familiar with the WebRTC technical stack to complete together; meanwhile, a large amount of server resources and network bandwidth are needed, multiple services are matched, and complicated service construction, integration, management and the like are achieved. Meanwhile, for tracking abnormal conditions, the link is complex, problems are not well discovered and processed, and the cost is high.
As shown in fig. 1, the equation provided in the embodiment of the present application may at least include the following steps S101 to S103.
S101, when detecting that the terminal equipment triggers and starts a double recording process, starting an MIC stream, an image stream and a TTS stream. The terminal device of this embodiment may be a mobile phone, a tablet, or other intelligent device, and software or a program specially used for double recording may be installed in the terminal device. The terminal equipment is connected with or not connected with an earphone. The user can start double recording by triggering the terminal device, as shown in fig. 2, and can start MIC streams and image streams and TTS streams simultaneously. The MIC stream is a microphone stream mainly used for acquiring audio data, the image stream may be continuous image frame data acquired by a camera, the TTS stream is a Speech synthesis stream, and Text To Speech, which is an abbreviation, i.e., "from Text To Speech", is a part of a human-computer conversation, so that a machine can speak. In dual transcription, TTS may also be considered to mean "risk cue". The general double recording process, only the recording of image stream and the recording of MIC stream, a basic double recording (sound recording) process is a question-and-answer form, which aims to record the user's knowledge and clear awareness of risks through the user's answers. For example, in the double recording process, a risk prompt "the yield of the product XZXX purchased by you is 5%, the risk level is medium risk, XXX, is broadcasted. Ask you if you know? The "user answers" i know ". Double recording is to record the audio-video data in the process of the question and answer. Both risk cues and user answers need to be recorded simultaneously.
The risk prompt is generally converted into an anthropomorphic voice through a professional speech algorithm, and the technology is called TTS. The TTS stream is a path of stream for recording the sound of the broadcasted risk prompt words in the double recording process. If the risk prompt is not worn by the earphone, the risk prompt is played from the loudspeaker, and at the moment, the MIC can record the sound played by the loudspeaker; however, when the user wears the headset (wired or bluetooth), the risk prompt is sent from the headset hole, and the MIC of the mobile phone cannot record the sound of the risk prompt. The embodiment of the application solves the problem that the TTS stream cannot be recorded in an earphone mode by introducing the recording of the TTS stream.
S102, acquiring video stream information in a double recording process in real time by using the MIC stream and the image stream, and acquiring TTS stream information in the double recording process by using the TTS stream and the image stream.
When MIC stream and recording (namely, starting to synchronously start recording and recording), TTS stream recording is started immediately; when the MIC stream and the image stream end recording (i.e., when the audio recording ends), the TTS stream recording is stopped. Therefore, the TTS stream can follow the time lines of the MIC stream and the image stream, so that the TTS stream can be recorded in real time, and the time consistency of the MIC stream, the image stream and the TTS stream is ensured.
With reference to fig. 3, the acquiring, by using the MIC stream and the image stream, the sound information in the double recording process includes:
a1, creating a local recording file, wherein the local recording file can be read and written randomly, and the local recording file is defaulted to be filled with null sound in real time. When the recording starts, a local recording file can be created first, the local recording file can be read and written randomly, and then empty sound is filled in the local recording file in real time in a default mode; and is consistent with the time lines of the MIC stream and the image stream.
A2, when the terminal equipment starts to play sound, stopping filling the local recording file with empty sound, and converting the local recording file into sound for filling the local recording file with the sound played by the terminal equipment in real time;
and A3, when the terminal equipment stops playing sound, stopping filling the sound played by the terminal equipment into the local recording file, and converting into filling empty sound into the local file in real time.
When the mobile phone starts to play sound (such as a risk prompt), the local recording file immediately stops filling the empty sound, and simultaneously, the sound played starts to be filled in real time; when the mobile phone stops playing the sound, the local recording file also correspondingly stops filling the playing sound, and the local recording file is converted into the local recording file which starts to fill the empty sound; and repeating the steps A3 and A4 until double recording is finished.
S103, when detecting that the terminal equipment finishes the double recording process, stopping the MIC stream, the image stream and the TTS stream to obtain a first file recorded by the MIC stream, a second file recorded by the image stream and a third file recorded by the TTS stream; and the MIC stream and the TTS stream are consistent in duration.
Further, after the step S103, the first file, the second file, and the third file may be uploaded to a cloud; and/or synthesizing the first file, the second file and the third file to obtain a double-recording video file.
And finally, obtaining the TTS stream recording file along with the end of the recording and the video recording. Therefore, MIC stream and image stream recording files, TTS stream recording files and corresponding video stream recording files can be uploaded or synthesized for final double-recording video generation. The method provided by the embodiment of the application can realize double recording in the earphone mode, and is low in technical threshold and controllable in cost.
Specifically, the method is divided into a local composition method and a server composition method. In the dual recording system of this embodiment, server-side synthesis is used, that is, after dual recording is completed, a file generated by 3 streams is uploaded to the server, and after the server takes the 3 files, an encoding and decoding operation is performed, and finally a video file is synthesized. Wherein the encoding and decoding operations use the currently mainstream FFMPEG technology.
For example, the overall double recording process of the present embodiment may be as follows:
1) And the user initiates double recording and starts recording.
2) The program respectively starts recording of the image stream, the MIC stream and the TTS stream, and synchronizes time schedule in real time, wherein the time schedule is based on the MIC stream sum, and consistency is ensured.
3) In the double recording process, a risk prompt is broadcasted, for example, "user is good, you buy financing product XXX, the product duration is 24 months, the risk level is medium risk, and the following risks exist: YYYY. Ask you if you already know? ". The user will then answer: "yes, i know. And repeating the steps to finish double recording.
4) And after double recording is finished, respectively obtaining an image stream recording file, an MIC stream recording file and a TTS stream recording file.
5) The files can be synthesized to generate a final double-recording video file; and uploading and retaining can be respectively carried out. The method can be specifically customized according to the requirements of customers.
The method of the embodiment has the following beneficial effects:
1. the user experience and the conversion rate are improved. In a scene that a user uses a mobile phone to perform self-service double recording, the user may be in a special environment, for example, for a user who pays attention to privacy, the user does not want to play sound, and the user is heard by other people or disturbs other people. Or the surrounding environment is noisy, the user wants to wear the earphone to perform double recording.
2. And (5) sensitive word quality inspection. Partial procurement customer requests, during double-recording, if the user speaks sensitive words, such as, for example, abusive words or illicit words. Double entries need to be detected and processed according to quality inspection exceptions. In the original recording scheme, the recorded audio is mixed with TTS voice and user response voice, and cannot be distinguished. According to the scheme, because the MIC stream, the image stream (user answer) and the TTS stream (risk prompt) are separated, the MIC stream, the image stream (user answer) and the TTS stream (risk prompt) can be distinguished, and quality inspection can be performed in a targeted mode.
