Ph.D. Level Research Topics in Speech Processing

Research area: Speech and audio coding, including:

• Quantization and classification, using vector quantization and density models such as Gaussian Mixture Models (GMMs);

• Objective and subjective quality measures;

• Complexity measures and complexity reduction.

Research area: Acoustic signal analysis, including:

• Spectral modeling through autoregressive (AR), cepstral and related models;

• Time-frequency representations through transforms and filterbanks;

• Model order estimation and reduction.

Research area: Environmental and biometrical signal enhancement and source identification, including:

• Dynamic spectral and cepstral modeling and adaptive filtering;

• Clustering through Gaussian Mixture Models (GMMs);

• Source placement and localization;

Office: Room D2-14

Note: Master's level research may be accommodated in the major topics above subject to suitable constraints.
