DOI: 10.1016/j.cub.2019.06.022

Abstract: Acoustic allometry consists of looking at how an organism's body size scales with the characteristics of its vocalizations. A typical finding based on this framework is that across mammals body size is reflected in the… read more here.

DOI: 10.1038/s41598-024-69620-z

Abstract: Glucose levels in the body have been hypothesized to affect voice characteristics. One of the primary justifications for voice changes are due to Hooke’s law, in which a variation in the tension, mass, or length… read more here.

DOI: 10.1093/scan/nsac033

Abstract: Abstract Our ability to infer a speaker’s emotional state depends on the processing of acoustic parameters such as fundamental frequency (F0) and timbre. Yet, how these parameters are processed and integrated to inform emotion perception… read more here.

recommendations! Published in 2025 at "IEEE Access"

DOI: 10.1109/access.2025.3564648

Abstract: We propose a system to enhance electrolaryngeal speech naturalness using automatically extracted phoneme representations. Phonemes provide sufficient information for predicting reasonably natural fundamental frequency patterns. Previous studies using forced-aligned phoneme labels to create shared features… read more here.
