• Abstract: Deciphering the acoustic language of chickens offers new opportunities in animal welfare and ecological informatics. Their subtle vocal signals encode health conditions, emotional states, and dynamic interactions within ecosystems. Understanding the semantics of these calls provides a valuable tool for interpreting their functional vocabulary and clarifying how each sound serves a specific purpose in social and environmental contexts. We apply advanced Natural Language Processing and transformer based models to translate bioacoustic data into meaningful insights. Our method integrates Wave2Vec 2.0 for raw audio feature extraction with a fine tuned Bidirectional Encoder Representations from Transformers model, pretrained on a broad corpus of animal sounds and adapted to poultry tasks. This pipeline decodes poultry vocalizations into interpretable categories including distress calls, feeding signals, and mating vocalizations, revealing emotional nuances often overlooked by conventional analyses. Achieving 92 percent accuracy in classifying key vocalization types, our approach demonstrates the feasibility of real time automated monitoring of flock health and stress. By tracking this functional vocabulary, farmers can respond proactively to environmental or behavioral changes, improving poultry welfare, reducing stress related productivity losses, and supporting more sustainable farm management. Beyond agriculture, this research enhances our understanding of computational ecology. Accessing the semantic foundation of animal calls may indicate biodiversity, environmental stressors, and species interactions, informing integrative ecosystem level decision making.

  This study aims to decode dairy cow contact calls by employing multi-modal data fusion techniques. We utilize the Natural Language Processing model to transcribe audio recordings of cow vocalizations into written form. We categorized vocalizations into high frequency calls associated with distress or arousal, and low frequency calls linked to contentment or calmness.
