Fig. 2 is a flowchart of a video generation method according to an embodiment of the present invention. As shown in fig. 2, the video generation method in the present embodiment includes the following steps.
In step S100, text information corresponding to the target document is acquired.
In this embodiment, the text information includes different forms of content such as characters, numbers, symbols, and the like, and is displayed in a sequential manner. And after receiving the target document, a back-end service layer in the video generation system analyzes the target document to obtain the text information corresponding to the target document.
In step S200, corresponding audio information is generated according to the text information.
In this embodiment, the text information is input to the preset speech synthesis model to generate corresponding audio information, where the audio information includes continuous multi-frame audio. The preset speech synthesis model can adopt a TTS model and is determined based on text corpus training stored in a database in advance.
When generating corresponding audio information according to the text information, in this embodiment, the phoneme information in the text information may be determined first, the phoneme duration (i.e., pronunciation time) and the fundamental frequency (i.e., pitch and intonation) may be predicted according to the pronunciation principle of the phoneme information, and finally, the phoneme and the corresponding duration and fundamental frequency are synthesized and converted into an original waveform, so as to output a sound signal (i.e., audio information). Alternatively, in this embodiment, the duration and fundamental frequency of the phoneme information corresponding to the text information may be determined by a segmentation model embedded in the speech synthesis model. Therefore, in the embodiment, the audio information corresponding to the text information is generated through the voice synthesis model, so that the generation efficiency is high, the efficiency of the video generation method is improved, and the process of processing the text information can enable other parts of different accents, emotions, breathing and human voice to be contained in the audio information, so that the reality of the audio information and real human voice is enhanced, and the effect of demonstrating the text information corresponding to the target document is improved.
Optionally, in this embodiment, TTS models with different parameters may be selected in different scenarios to generate different forms of audio information. For example, audio information with different timbres, morphemes, volumes or tones can be generated by adjusting different model parameters, audio information with different audio coding formats at different sampling rates can be generated, and audio information with more characteristics can be generated according to emotion or other forms of labels of text information. Therefore, different forms of audio information are generated by selecting the speech synthesis models with different parameters, the use requirements under different use scenes are met, and the applicability of the video generation method in the embodiment is improved.
In step S300, a preset target digital character is driven based on audio information to generate an avatar video.
In this embodiment, the preset target digital image is selected from a plurality of digital images based on the user requirements of the front layer in the video generation system. The target digital image may be any human image, and the target digital image may be determined based on a photographed image including the real human image, or may be determined by extracting a frame including the real human image from the video. For example, when the target digital image is determined by a video containing a human image, the target digital image may be generated by shooting with green or blue as a background during shooting or photographing, and subtracting the background by using a color key of a special effects machine during post-production. Therefore, the target digital image is more convenient to determine and use, and the more common determination mode is beneficial to improving the generation efficiency of the virtual image video and reducing the generation cost of the virtual image video.
Fig. 3 is a flowchart of generating an avatar video according to an embodiment of the present invention. As shown in fig. 3, the method of generating an avatar video in the present embodiment includes the following steps.
In step S310, a part motion sequence corresponding to the text information is generated from the audio information.
In the present embodiment, the part motion sequence includes a facial motion sequence. In the embodiment, when the avatar video is generated, the corresponding facial motion sequence is generated by processing the audio information by using the neural network model which is generated by training in advance and generates the motion sequence. Therefore, the audio information is converted into the feature vector through the neural network model, the facial action sequence is predicted and mapped based on the feature vector, and the efficiency of demonstrating the facial action in the virtual image video corresponding to the target digital image can be greatly improved.
Optionally, the facial motion sequence in this embodiment includes a mouth motion sequence. In this embodiment, a sequence model is used to generate a mouth action sequence corresponding to the text information according to the audio information. The sequence model may be a GRU, LSTM, RNN, or the like model. In the process of generating the mouth action sequence, firstly, processing audio information through a sequence model, extracting Mel spectrum (Mel Spectrum) characteristics in the audio information, predicting coordinates and phoneme labels of key parts of the mouth in the process of broadcasting the audio information according to the Mel spectrum characteristics to obtain a target digital image, splicing the coordinates and the phoneme coordinates of the key parts of the mouth and the audio information to generate a splicing result, and finally processing the splicing result to obtain corresponding action parameters of the facial mouth shape when each frame of audio is output.
Optionally, in order to make the generated avatar video more vivid, in this embodiment, after the expressionless mouth motion sequence is generated, the text information is further analyzed, the emotion keywords in the text information are located, tag information is labeled on the emotion keywords, an emotion tag is generated, and the mouth motion sequence with specific expression changes is generated according to the generated expressionless mouth motion sequence and the emotion tag. The emotion labels comprise emotion keywords (such as positive, happy, positive energy and the like), broadcast timestamps of the emotion keywords, emotion characteristics and the like.
Optionally, after generating the facial motion sequence with expression changes, the embodiment may further add an eye motion sequence to the facial motion sequence, and/or add a limb motion sequence based on the part motion sequence of the target digital image. For example, when the mouth of the target digital character moves as an active keyword in the category of "look", actions such as blinking eyes, like likes may be added to the sequence of facial actions. Therefore, the virtual image video is more vivid through the combination of the mouth action sequence, the eye action sequence and the limb action sequence. Meanwhile, due to the fact that corresponding timestamps are arranged between the emotion label settings and the corresponding audio information, the corresponding correspondence between the corresponding mouth action, eye action and limb action under the same audio information can be guaranteed, and the corresponding mouth action, eye action, limb action and the like are displayed while the audio information is broadcasted, so that the virtual image video is displayed more vividly and vividly.
In step S320, a corresponding avatar video is generated according to the part motion sequence and the preset target digital avatar.
In this embodiment, after the part action sequence corresponding to the audio information is generated, in a neural network model preset by the preset target digital image input value and the part action sequence corresponding to the audio information of the target document, a corresponding part action diagram is generated according to the action parameters in the part action sequence, and the part action diagram is spliced to the position of the corresponding part in the preset target digital image, so that the part action sequence is adapted to the target digital image, and further, an avatar video under the audio information corresponding to the text information in the target document is generated.
Alternatively, in order to make the quality of the generated avatar video higher, the position action map may be adjusted according to the position action map and the corresponding position in the target digital avatar. For example, the part motion map is precisely attached to the position corresponding to the target digital Image by an Image Warping algorithm (i.e., an Image Warping algorithm, such as an Inverse Distance weighted difference IDW-Inverse weighted interpolation), so that the degree of adaptation between the motion sequence corresponding to the part motion map and the target digital Image is improved, the quality of the generated virtual Image video is improved, and the quality and the display effect of the subsequently generated target video are improved.
In step S400, a target video is generated according to the avatar video and a video corresponding to the target document, so that the target document is interpreted by a target digital avatar in the target video.
In the embodiment, the target video is generated according to the virtual image video and the video corresponding to the target document, so that the target digital image explains the target document, the interestingness of target document demonstration is enhanced, the text demonstration effect can be improved, and meanwhile, the explanation cost of a real person can be reduced.
Fig. 4 is a flow chart of generating a target video according to an embodiment of the present invention. As shown in fig. 4, the target video is generated by the following steps in the present embodiment.
In step S410, the target document is converted into a corresponding video file.
In this embodiment, after receiving the text-to-video function issued by the front end layer, the target document is converted into a corresponding video file based on the document conversion service module in the service application module. The text information in the target document is sequentially provided with the time stamps according to the display sequence in the target document, and correspondingly, when the video file is generated, the text information displayed in the video file still carries the time stamps so as to ensure the display sequence of each text information in the text demonstration process.
In step S420, the avatar video is synthesized with the video file to generate a target video.
In the embodiment, the virtual image video is added into the video file, the target video is generated so that the text demonstration process of the target document is realized, the three display modes of the video file, the audio information and the target virtual image are combined simultaneously, the text information in the target document is displayed through the video file, the text information content is broadcasted through the audio information, the explanation of the text information is simulated through the action behavior of the target virtual image, the text demonstration process corresponding to the target document is realized, the broadcasted sound-shape effect is good, the interest of the text demonstration can be enhanced, and the performance of meeting the requirements of different audiences through the text demonstration is improved.
Further, in the present embodiment, the audio information corresponding to the avatar video has a temporal correspondence with the text information displayed in the video file. Specifically, the action or behavior of the target digital character and the audio information in the avatar video correspond to text information at a word level, and the text information corresponding to the avatar video is the same as the text information corresponding to the video file, so that the timestamps corresponding to the same text information fields in the avatar video and the video file are the same when the explanation process is presented. Therefore, through the setting and the correspondence of the timestamps, in the process of playing the target video, the broadcasting of the audio information is aligned with the display time of the corresponding text information, and the action behavior of the target digital image is aligned with the corresponding audio information time, so that the matching of the audio information, the text information and the action behavior of the target digital image can be ensured, and the text demonstration effect is further optimized.
Further, in order to further optimize the text demonstration effect, the target digital image in the target video of the embodiment has editability, and the video generating method of the embodiment further includes:
in step S500, attribute information of a target digital character in a target video is adjusted.
In this embodiment, the attribute information includes at least one of a display position and a display size of the target digital character in the target video. Therefore, the display position and the display size of the target digital image in the target video are adjusted by adjusting the attribute information of the target digital image in the target video, and the display effect of the target video and the text demonstration effect of the corresponding target document are further optimized.
Optionally, in this embodiment, different layers are respectively set for the avatar video and the video file to display respective corresponding contents, so as to adjust the display effects of the avatar video and the video file in the corresponding layers, for example, after a layer corresponding to the avatar video is selected, attribute information of a target digital avatar in the avatar video may be adjusted based on an operation option in the current layer, or after a layer corresponding to the video file is selected, display information such as a text font or a text interval in the video file may be adjusted based on an operation option in the current layer. Therefore, through setting different layers, the adjustment of the content in the virtual image video and the video file can obtain a better display effect on the premise of mutual noninterference, the interestingness of target document display can be further enhanced, and the text demonstration effect of the target document is optimized.

Meanwhile, the interest of target document display can be further enhanced and the text demonstration effect of the target document can be optimized by adjusting the attribute information of the target digital image in the target video.
