My research interests include a broad range of topics related to speech, signal processing, and language. In recent years, this has included the following topic areas:
Relationship between articulatory kinematics and speech acoustics
In collaboration with Dr. Jeff Berry of Speech Pathology and Audiology
- Eletromagnetic Articulography (EMA) data collection
- Acoustic to Articulatory inversion
- with applications to Computer Aided Language Learning and Pronunciation Assessment
- Articulatory to Acoustic Synthesis mapping
- Kinematics-driven voice modification for real-time acoustic feedback
Analysis and classification of animal vocalizations, and bioacoustic signal processing
In collaboration with numerous collaborators in the field of bioacoustics.
- Automatic vocalization classification and repertoire analysis
- Identification and clustering of individuals from their vocalizations
- Acoustic population monitoring and assessment
- Relationship between behavior and vocal patterns
- Auditory-model driven signal enhancement for bioacoustic data
Speech enhancement
- Signal-to-noise ratio estimation and tracking
- Perceptually-driven signal representations
- Intelligibility assessment and improvement
Dynamical systems modeling of speech signals
In collaboration with Dr. Richard Povinelli
- Statistical modeling of Reconstructed Phase Spaces (RPS) for speech recognition
- Dynamical trajectories withing RPSs for speech enhancement
Collaborative work with Tsinghua University in Beijing
I also have a close research collaboration with Tsinghua University and Professor Jia Liu,
and have worked with their research group on several speech projects
- Language identification
- Robust speech recognition using microphone arrays
- Low resource speech recognition
