MEDIAMOSA TRANSCRIPTING TECHNOLOGY

• The number of AV-archives on the Internet increases rapidly

• Archiving is not enough: disclosure and reusing is required!

• The use of speech technology is needed (Reduce human effort).

Disclosure of audiovisual archives

UK National Film and Television Archive, Berkhamstedhttp://www.flickr.com/people/footage/

Huge amount of workand no time-coded relations with video

Adding metadata, the traditional approach:Manual annotation




Adding metadata, the new approach:Using speech-to-text technology for metadata generation

Speech Recognition(Speech-to-Text)Time-coded Transcript

Indexing and Search:Search on fragment level

Audio Extraction
