Beyond the Baseband: Adaptive Multi-Band Encoding for Full-Spectrum Bioacoustics Classification

Eklavya Sarkar, Marius Miron, David Robinson +6

Animals hear and vocalize across frequency ranges that differ substantially from humans, often extending into the ultrasonic domain. Yet most computational bioacoustics systems rel…

Towards Leveraging Sequential Structure in Animal Vocalizations

Eklavya Sarkar, Mathew Magimai. -Doss

Animal vocalizations contain sequential structures that carry important communicative information, yet most computational bioacoustics studies average the extracted frame-level fea…

On feature representations for marmoset vocal communication analysis

Eklavya Sarkar, Kaja Wierucka, Alexandra B. Bosshard +2

The acoustic analysis of marmoset (Callithrix jacchus) vocalizations is often used to understand the evolutionary origins of human language. Currently, the analysis is largely carr…

Comparing Self-Supervised Learning Models Pre-Trained on Human Speech and Animal Vocalizations for Bioacoustics Processing

Eklavya Sarkar, Mathew Magimai. -Doss

Self-supervised learning (SSL) foundation models have emerged as powerful, domain-agnostic, general-purpose feature extractors applicable to a wide range of tasks. Such models pre-…

On the Utility of Speech and Audio Foundation Models for Marmoset Call Analysis

Eklavya Sarkar, Mathew Magimai. -Doss

Marmoset monkeys encode vital information in their calls and serve as a surrogate model for neuro-biologists to understand the evolutionary origins of human vocal communication. Tr…

Can Self-Supervised Neural Representations Pre-Trained on Human Speech distinguish Animal Callers?

Eklavya Sarkar, Mathew Magimai. -Doss

Self-supervised learning (SSL) models use only the intrinsic structure of a given signal, independent of its acoustic domain, to extract essential information from the input to an…
