Research Progress of Audio Information Technology in Agricultural Field

Abstract

Audio technology, as a vital modality for agricultural information perception, offers significant advantages, including non-invasiveness, strong real-time responsiveness, and low implementation cost. These features enabled its broad application potential in the context of smart agriculture. A comprehensive review of recent advancements and representative applications of audio technology in both livestock farming and plants production was provided. In the domain of animal husbandry, it highlighted audio-based methods for recognizing feeding, estrus, drinking, and egg-laying behaviors, along with key techniques for emotion assessment, stress monitoring, disease detection, voiceprint identification, and sound source localization. In the plants sector, the acoustic emission mechanisms under abiotic stresses such as drought and freezing were covered, the regulatory effects of specific sound frequencies on plant physiology and gene expression were explored. Additionally, the current status of intelligent voice interaction systems in agriculture was outlined, including their roles in information services, machinery control, and voice-based consultation. Finally, it emphasized future research directions, advocating for the development of multimodal sensing integration, edge computing optimization, and standardized audio data platforms to advance the intelligent, efficient, and scalable application of audio technologies in modern agricultural systems.
