Abstract
A system and method of delivering an information output to a viewer of a live performance. The information output can be displayed text or an audio description at predefined times in the live performance relative to stage events. A follower script with entries organised along a timeline, and metadata at time points between at least some of the entries is generated. The metadata is associated with stage events in the live performance. The system uses speech recognition to track spoken dialogue against the entries in the follower script, and the stage events, to aid in following the live performance.
Claims16
A caption delivery system for displaying captions during a live performance, the system comprising:
- a memory component storing a follower script and a caption script, the follower script including waypoints associated with performance cues;
- a speech follower component operable to recognise spoken dialogue of the performance and to compare the spoken dialogue with the follower script to track the location in the follower script of the spoken dialogue to identify when a caption is to be displayed;
- the caption output module configured to access from the caption script the caption for display at each location in the follower script associated with a caption;
- a cue handler component which stores performance cue identifiers with associated cue metadata and which is configured to receive performance cues detected in the live performance and output cue signals to the speech follower component to thereby assist the speech follower component to determine the location based on the waypoints at the detected cues.
A method of delivering an information output to a viewer of a live performance, the information output being at least one of displayed text and an audio description at predefined times in the live performance relative to stage events by providing a follower script with entries organised along a timeline, and metadata at timepoints between at least some of the entries, wherein the metadata is associated with stage events in the live performance, and using speech recognition to track spoken dialogue against the entries in the follower script, and the stage events to aid in following by live performance.
