The recently-established Laboratory for Recognition and Organization of Speech and Audio (LabROSA) at Columbia has the mission of developing techniques to extract useful information from sound. This covers a range of areas:I will present more details on some current and new projects, including:
- General-purpose structure discovery and recovery, i.e. the basic segmentation problem over scales from subwords to episodes, and on both time and frequency dimensions;
- Source/object-based organization: Explaining the observed signal as the mixture of the independent sources that would be percieved by listeners;
- Special-purpose recognition and characterization for specific domains such as speech (transcription, speaker tracking etc.), music (classification and indexing), and other distinct categories.
- Tandem acoustic modeling: Noise-robust speech recognition features calculated by a neural net.
- The Meeting Recorder project: Acoustic information extraction applications in a conventional meeting scenario.
- Machine Listening: Hearing for autonomous devices in the real world.
