Speech Decomposition Based on a Hybrid Speech Model and Optimal Segmentation
Alfredo Esquivel Jaramillo, Jesper Kjær Nielsen, Mads Græsbøll Christensen
In a hybrid speech model, both voiced and unvoiced components can coexist in a segment. Often, the voiced speech is regarded as the deterministic component, and the unvoiced speech…
Signal-Adaptive and Perceptually Optimized Sound Zones with Variable Span Trade-Off Filters
Taewoong Lee, Jesper Kjær Nielsen, Mads Græsbøll Christensen
Creating sound zones has been an active research field since the idea was first proposed. So far, most sound zone control methods rely on either an optimization of physical metrics…
Bayesian Pitch Tracking Based on the Harmonic Model
Liming Shi, Jesper Kjaer Nielsen, Jesper Rindom Jensen +2
Fundamental frequency is one of the most important characteristics of speech and audio signals. Harmonic model-based fundamental frequency estimators offer a higher estimation accu…
Model-based Speech Enhancement for Intelligibility Improvement in Binaural Hearing Aids
Mathew Shaji Kavalekalam, Jesper K. Nielsen, Jesper B. Boldt +1
Speech intelligibility is often severely degraded among hearing impaired individuals in situations such as the cocktail party scenario. The performance of the current hearing aid t…
A Variational EM Method for Pole-Zero Modeling of Speech with Mixed Block Sparse and Gaussian Excitation
Liming Shi, Jesper Kjær Nielsen, Jesper Rindom Jensen +1
The modeling of speech can be used for speech synthesis and speech recognition. We present a speech analysis method based on pole-zero modeling of speech with mixed block sparse an…
