Stephen D. Voran and Jaden Pieper, “A Powerful, Fixed-Size Modulation Spectrum Representation for Perceptually Consistent Speech Evaluation,” Technical Memorandum NTIA TM-24-274, September 2024
We develop the wideband fixed-size modulation spectra (FMS) and show that they contain the necessary information to perform perceptually consistent evaluation of speech. We compare FMS with the already established frame-based modula-tion spectra as r...

Jaden Pieper and Stephen D. Voran, “AlignNet: Learning Dataset Score Alignment Functions To Enable Better Training of Speech Quality Estimators,” Conference Paper, July 2024
We develop two complementary advances for training no-reference (NR) speech quality estimators with independent datasets. Multi-dataset finetuning (MDF) pretrains an NR estimator on a single dataset and then finetunes it on multiple datasets at once,...
