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
Research Assistantships are currently available in the Speech Lab, related to projects in Computer Aided Language Learning and Computer Aided Pronunciation Training. More information is available in this RA Position Announcement. For more information or to apply for a position, contact Dr. Johnson.
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
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
