2 results about "Broadcast quality" patented technology

This invention relates to the field of speech signal processing and live broadcast quality control technology, and discloses a method and system for real-time monitoring and correction of speech anomalies in news live broadcasts. The method includes: extracting multi-dimensional acoustic feature vectors from the announcer's speech signal in real time by frame segmentation and storing them in a circular feature buffer; performing parallel detection of abnormal pauses, speech errors, and sudden volume changes based on the feature vectors; pushing prompts through in-ear monitors, highlighting deviation positions on the teleprompter, or triggering a dynamic compressor to smooth the volume according to the type of abnormal event; recording abnormal events to generate a broadcast quality analysis report and using this report to correct the detection threshold. This invention achieves millisecond-level real-time perception and immediate correction assistance for broadcast anomalies, significantly shortening the response delay of traditional manual monitoring.

The application relates to the technical field of speech signal processing and live broadcast quality control, and discloses a news live broadcast speech abnormality real-time monitoring and correction method and system, which comprises the following steps: extracting a multi-dimensional acoustic feature vector from a real-time frame of a broadcaster's speech signal and storing the feature vector in a ring feature buffer; synchronously performing parallel detection of abnormal pause detection, speech error deviation detection and volume mutation detection based on the feature vector; pushing a prompt sound through an ear return, highlighting a deviation position on a teleprompter or triggering a dynamic compressor to smooth the volume according to the type of an abnormal event; recording the abnormal event to generate a broadcast quality analysis report and correcting the detection threshold according to the report; and the application realizes millisecond-level real-time perception and instant correction assistance for broadcasting abnormalities, and significantly shortens the response delay of traditional manual monitoring.
