The invention provides a text punctuation model establishment method and further provides a punctuation method and device and computer equipment corresponding to the text punctuation model establishment method. The text punctuation model establishment method includes: subjecting a training corpus to word segmentation to obtain words corresponding to the training corpus; adding feature information to the words, wherein the feature information comprises pause information; using a conditional random field algorithm to train the words corresponding to the training corpus on the basis of the feature information to obtain a text punctuation model.

The invention discloses a punctuation mark adding method, device and computer device. The punctuation mark adding method includes encoding each character in a to-be-recognized text and generating feature vectors of the characters according to the codes, the segmentation properties and the segmentation borders of the characters; inputting the features vectors of the characters into a bidirectionallong-short-term memory model and generating input features of the characters through the bidirectional long-short-term memory model; inputting the input features of the characters into a deep neural network model and acquiring the possibility corresponding to an adding result of each punctuation mark after the characters; adding the punctuation marks after the characters according to the adding results of the highest possibilities. According to the invention, bidirectional context information of characters in the to-be-recognized text can be utilized for punctuation mark adding for the to-be-recognized texts, so that punctuation mark adding accuracy is improved and user experience is improved.

The embodiment of the invention discloses a subtitle generation method and device. Aiming at the process of generating a subtitle by multiple voice segments formed by dividing a mute segment and froma same audio stream, text separately corresponding to the multiple voice segments is acquired via voice recognition. When the subtitle is determined according to the text corresponding to the target voice segments, a to-be-processed text set including the text corresponding to the target voice segments is determined. Then, separators in the to-be-processed text set are used as bases for determining the subtitle text from the to-be-processed text set; as the separators are added based on semantics when characters in the voice segments are recognized, the text parts between the separators are complete sentences, the reasonable semantics can be embodied, so that the possibility that the incomplete sentence occurs in the subtitle text determined by the separators is greatly reduced, when the subtitle text is displayed as the subtitle of a corresponding audio stream time shaft section, the user watching an audio and video can be assisted to learn the content of the audio and video, and theuser experience is improved.

The invention discloses a technology for realizing real-time subtitle overlay during a video call and applications of the technology. The technology comprises subtitle software, and comprises the following steps: S1, a voice recognition algorithm, namely, through a machine learning algorithm, capturing audio data in a video in real time, and converting the audio data into language data with practical meaning; S2, a character converting algorithm, namely, carrying out algorithm processing on the acquired voice data so that character information is obtained through converting in real time; S3, asubtitle display algorithm, namely, carrying out real-time character-by-character or word-by-word display on the character information; S4, an automatic sentence punctuating algorithm, namely, analyzing an audio file, so that the starting and pausing points of one sentence are acquired; and S5, a character and audio/video overlay method, namely, directly displaying characters to a video interfacein an overlay manner, so that video captions are formed, wherein the video interface does not assign the display positions of the character subtitles. Through the technology for realizing real-time subtitle overlay during a video call and the applications of the technology, after the complete sentence is acquired, all the displayed characters can be updated according to the meaning of the complete sentence.

Technology for realizing real-time subtitle overlay during video call and applications of technology

The invention discloses a punctuation processing method and a device of a speech recognition text. The punctuation processing method comprises the following steps: speech recognition is performed on current inputted speech data namely target speech data, so as to obtain a current recognized text; punctuation information of a historical recognized text before the current recognized text is obtainedby predicting, and displayed to a user, but the punctuation prediction result may be inaccurate, so that the content of the current recognized text is further utilized to judge whether the punctuation prediction result of the historical recognized text is accurate or not; if not, the punctuation prediction result of the historical recognized text is corrected, and the corrected punctuation information is displayed to the user. Due to adoption of the punctuation processing method disclosed by the invention, combined with the current recognized text, punctuation amending is performed on the historical recognized text, so that the accuracy of the punctuation generating result can be increased.

Punctuation processing method and device of speech recognition text

The invention discloses a real-time subtitle display method and system. The real-time subtitle display method comprises the steps of receiving speech data of a speaker; performing speech recognition on the current voice data to acquire a subtitle text to be displayed; adding punctuations to the subtitle text to acquire subtitle text clauses; determining and marking whether each text clause requires to be paragraphed at the end position or not; determining a subtitle display basic unit according to prosodic features of the speaker; and displaying the subtitle text according to the subtitle display basic unit. By using the real-time subtitle display method and system disclosed by the invention, an information transferring effect of the speaker can be improved.
