Multiple strategies have evolved to compensate for masking noise, leading changes in call features. One adjustment is the Lombard effect, an increase amplitude response noise. Another strategy involves production periods where noise absent. While mechanisms underlying vocal adjustments been well studied, avoidance remain largely unclear. We systematically perturbed ongoing phee calls of marmosets investigate strategies. Marmosets canceled their after onset and produced longer noise-phases ended. Additionally, number uttered syllables decreased during perturbation. This behavior persisted beyond noise-phase. Using machine learning techniques, we found that a fraction single phees were initially planned as double became interrupted first syllable. Our findings indicate use different suggest flexibility at complexity levels marmoset brain.

In recent years, vocal music is becoming more and important to daily life, which can cultivate emotion adjust pressure, but at present, teaching faced with an increasingly serious shortage of teacher resources. Therefore, it particularly develop a system using the computer-aided function. First, algorithm flow designed in detail according principle computer neural network technology, performance characteristics are extracted by Fourier transform its improved function, key modules frame structure data processing gave design code. Finally, taking piano as example, players different steel bar grades were selected test accuracy evaluation. The results show that reflect real level performers, beneficial teaching. improvement great practical significance traditional mode make education reasonable.

Linguistic law-like compression strategies emerge to maximize coding efficiency in marmoset vocal communication

Human language follows statistical regularities or linguistic laws. For instance, Zipf's law of brevity states that the more frequently a word is used, shorter it tends to be. All human languages adhere this structure. However, unclear whether emerged de novo in humans also exists non-linguistic vocal systems our primate ancestors. Using conditioning paradigm, we examined capacity marmoset monkeys efficiently encode vocalizations. We observed marmosets adopted compression strategies at three levels: (i) increasing call rate, (ii) decreasing duration and (iii) proportion short calls. Our results demonstrate marmosets, when able freely choose what vocalize, exhibit consistent with go beyond their context-specific natural behaviour. This suggests laws lineage.
