“…Target guinea pig calls consisted of the chut, wheek, rumble, and whine calls. The guinea pig calls varied in both their long-term spectra (e.g., the wheek had higher frequency content than the others) as well as in other spectrotemporal properties 33 . While vocalization recordings from each species typically had high (>15 dB) SNR, recordings contained some colony noise, which had low-pass spectra.…”

For robust vocalization perception, the auditory system must generalize over variability in vocalization production as well as variability arising from the listening environment (e.g., noise and reverberation). We previously demonstrated using guinea pig and marmoset vocalizations that a hierarchical model generalized over production variability by detecting sparse intermediate-complexity features that are maximally informative about vocalization category from a dense spectrotemporal input representation. Here, we explore three biologically feasible model extensions to generalize over environmental variability: (1) training in degraded conditions, (2) adaptation to sound statistics in the spectrotemporal stage and (3) sensitivity adjustment at the feature detection stage. All mechanisms improved vocalization categorization performance, but improvement trends varied across degradation type and vocalization type. One or more adaptive mechanisms were required for model performance to approach the behavioral performance of guinea pigs on a vocalization categorization task. These results highlight the contributions of adaptive mechanisms at multiple auditory processing stages to achieve robust auditory categorization.

“…Guinea pig calls were primarily recorded from four male and one female guinea pigs. Male guinea pigs were placed in pairs in a sound-attenuating booth, sometimes in two different chambers separated by an acrylic divider 33 . A directional condenser microphone, suspended from the sound booth ceiling, was used to record these vocalizations.…”
