Abstract. Zebra dove's voice competition has become more popular in Thailand and many other South East Asian countries. Even though there are specific judging rules to follow, the results could still be somewhat subjective since each judge has various levels of expertise, knowledge, feeling, and experiences. Some criteria are quite straightforward and not very difficult to judge, but some could be very challenging and subjective due to several reasons including the limitations of human ears and personal preferences--aesthetic appreciation. This paper proposes a preliminary framework that could be used in developing a decision support system that exploits time series representation and signal processing that could potentially help alleviate this problem in judging the voice's quality of each zebra dove.
