Virage Launches AudioLogger 1.0 at Demo 99 Conference
Industry's first real-time audio cataloger makes video searchable by spoken words, speaker names and audio types INDIAN WELLS, Calif.--Feb. 8, 1999--Virage, Inc. today debuted and announced the immediate availability of the 1.0 version of its AudioLogger software, the first application that automatically transforms the audio content of video into searchable text in real time. By intelligently "listening" to the audio track of a video, the AudioLogger identifies spoken words, speaker names and audio types, generating a powerful index that allows users to search for and find specific segments of video. The announcement was made at the Demo 99 Conference, the industry's premiere showcase of leading edge products and technologies.
"At CNN, the vast majority of video that we deal with is raw footage that contains no embedded textual material, such as closed captioning, from which to construct an index of the content," said Kevin Ivey, Vice President of Research & Development at Cable News Network, Inc. "We are very excited about the introduction of the AudioLogger because of its potential to allow broadcasters to extract and index, in real time, the wealth of information contained in the audio tracks of video. The ability to search incoming news feeds by speaker or by spoken content would enable us to accelerate the rate at which we bring stories to air, one of CNN's major objectives. We see this as an important developing component to our ongoing content management efforts.""Making video searchable is the perfect application for today's audio and speech technologies," said Paul Lego, chief executive officer of Virage. "Virage extends the benefits of searchable video beyond the broadcast market by automatically turning the audio portion of any video into searchable text. The combination of the AudioLogger and VideoLogger create a unique solution that transforms video into a powerful decision support and communication tool for the corporate and Internet markets.
Developed around a powerful and extensible framework, AudioLogger is a PC-based application that combines three unique audio processing engines to automatically generate keyword, speaker identification and audio classification indices from a raw audio signal. Whether the signal originates from a satellite, a VTR, a live feed or directly from a microphone, AudioLogger transforms the audio portion into a rich index of textual content in real time, thereby eliminating the dependency on tedious manual annotation or costly closed captioning.
Speech Keyword Engine AudioLogger generates a keyword index for any speech sample using IBM's ViaVoice technology for Broadcast Speech Transcription. This speech recognition engine handles continuous speech in real time and is speaker independent, eliminating the need for it to be pre-trained for individual speakers. The engine also incorporates special filtering to eliminate background noise and other signal contamination.
Speaker Identification Engine The AudioLogger is the first commercial product to incorporate IBM's real-time ViaVoice technology for Broadcast Speaker Identification. AudioLogger identifies voices from a user-defined library of up to 300 speakers per session, regardless of the words or even the language spoken. By simply providing a short speech sample, users can easily add new speakers to the library. Multiple libraries can be created to support different content types and sources.
Audio Classification Engine AudioLogger also generates an audio classification index that allows users to locate specific audio cues. For example, a segment might be classified as speech, music, ambient noise or silence. AudioLogger combines these various audio indices with the video indices created by Virage's VideoLogger. The result is an extremely accurate index of the video that can be exported to a variety of data stores, such as Web servers, database management systems or media asset management systems, allowing searchable video to be incorporated into a broad range of applications used throughout the enterprise. With the Virage VideoLogger and AudioLogger applications users no longer have to spend hours creating transcripts or adding annotations manually to make video searchable--it all happens automatically, effortlessly and in real time.
The Virage AudioLogger 1.0 is currently shipping with a unit price of $15,000 (U.S.). For additional product or purchase information, contact Virage Sales at (650) 573-3236 or info@virage.com.
