Live Broadcast Script Synchronization via Speech Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Social networking systems lack the ability to provide users with a seamless live-broadcasting experience that allows for real-time interaction and media streaming, particularly in video or audio formats, while enabling users to deliver prepared scripts during live broadcasts.
Innovation Solution
The social networking system implements a live-broadcast service that allows users to broadcast media streams in real-time, providing a script-composing functionality for users to prepare and deliver scripted content during live sessions, with features like script selection, display, and synchronization with vocal expressions, enabling users to broadcast using a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users broadcast media streams in real-time with script-composing functionality, then user engagement and sense of presence are improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent combines multiple functions (media streaming, script composition, speech recognition, and script display) into a single integrated live-broadcast service. The script-composing functionality is merged with the broadcasting interface, allowing users to prepare and deliver scripted content through one unified system rather than separate tools, thereby improving engagement without proportionally increasing complexity.
Solution Approach 2:
The live-broadcast service is designed as a multi-functional platform that handles media capture, script composition, speech-to-text conversion, and real-time script display within a single service. This universal approach allows the same system to perform diverse functions (broadcasting, scripting, recognition, display) that would traditionally require multiple separate applications or devices.
2Measurement precision
If speech recognition is used to identify words in vocal expressions, then script synchronization is improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing transcribed script content before the live broadcast. The speech recognition engine converts vocal expressions to text in advance or in real-time with optimized processing, so that when it's time to synchronize and display the script, the text is already prepared and ready for immediate presentation, reducing latency during the actual broadcast.
3Ease of operation
If a single device is used for broadcasting with script display, then ease of operation is improved, but display area and information visibility are limited
Solution Approach 1:
The script display is segmented into manageable portions rather than showing the entire script at once. The interface divides the script content into sections that can be displayed sequentially or in focused views, allowing the limited screen real estate to effectively present relevant information without overwhelming the user or requiring a larger display area.
Data Source
AI summary
In one embodiment, a method includes retrieving, from one or more data stores, a script including multiple text strings, where the script is associated with a user of a social-networking system. The method also includes capturing an incoming media stream including audio data corresponding to vocal expression by the user, where the media stream is transmitted to the social-networking system for broadcast and identifying, using a speech recognition process, one or more words in the vocal expression corresponding to a text string of the script. The method also includes providing the corresponding text string for display in conjunction with a subsequent text string of the script.
