However, humans cannot accurately understand the emotions or intentions behind animal vocalizations.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This research focuses on developing a deep neural network model that classifies dog barks according to emotional states. The study uses&nbsp;YAMNet, an environmental sound classification model, and trains it with publicly available datasets as well as bark recordings collected from a puppy. Dog vocalizations are categorized into emotional classes such as excitement and desire, loneliness and anxiety, communication, caution, and intimidation, with the goal of estimating a dog&#8217;s emotional state from its bark.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The model was fine-tuned using the collected audio data and evaluated for classification performance. Experimental results achieved an accuracy of approximately 80%,&nbsp;demonstrating&nbsp;high performance for several emotion categories. In addition, a web-based application was developed as an example of practical use, allowing users to upload dog bark audio files and view the predicted emotional classification results.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Future work aims to improve classification accuracy by incorporating not only bark sounds but also environmental information and individual characteristics of dogs.&nbsp;&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"601\" height=\"362\" src=\"https:\/\/www.comm.tcu.ac.jp\/masuda-lab\/wordpress\/wp-content\/uploads\/2026\/06\/20260626_\u30b3\u30f3\u30c6\u30f3\u30c4C_\u753b\u50cf.png\" alt=\"\" class=\"wp-image-1966\" style=\"aspect-ratio:1.6651818856718634;width:840px;height:auto\" srcset=\"https:\/\/www.comm.tcu.ac.jp\/masuda-lab\/wordpress\/wp-content\/uploads\/2026\/06\/20260626_\u30b3\u30f3\u30c6\u30f3\u30c4C_\u753b\u50cf.png 601w, https:\/\/www.comm.tcu.ac.jp\/masuda-lab\/wordpress\/wp-content\/uploads\/2026\/06\/20260626_\u30b3\u30f3\u30c6\u30f3\u30c4C_\u753b\u50cf-300x181.png 300w\" sizes=\"auto, (max-width: 601px) 100vw, 601px\" \/><figcaption class=\"wp-element-caption\"><strong><strong>Figure.
