Podcast在美國與台灣相繼竄起，號稱搶佔第二注意力市場，在科技發展加速資訊爆炸且碎片化的生活型態下，Podcast被譽為通勤、運動、做家事時的聆聽首選；Podcast收聽常發生於多工任務情境，但以往對於Podcast相關學術研究，較少以多工任務之角度去探討，而是以使用與滿足理論之觀點去研究Podcast，因此本研究以任務科技適配理論作為主要架構，根據任務及科技本身的角度去探討Podcast，並且將聽覺特性、支配特性加入考量，並搭配使用與滿足理論來建立研究模型。
本研究結果發現：多工任務特性與科技聽覺特性達成適配，並且多工任務特性相較於科技聽覺特性有較大的正向影響；科技支配特性對於任務科技適配的影響則不成立；科技聽覺與個人聽覺達成適配，其中以個人聽覺的影響較大；科技支配與個人支配達成適配，其中以科技支配的影響較大；任務科技適配、科技聽覺適配、科技支配適配、使用與滿足皆正向影響Podcast使用意圖，以任務科技適配影響為最大，其次是使用與滿足。

Podcasts have sprung up in the United States and Taiwan one after another, claiming to seize the second attention market. Under the accelerated information explosion and fragmented lifestyle, podcasts are known as the first choice for listening during commuting, sports, and household chores. Podcast listening often occurs in multitasking situations, however, in past academic research on podcast, it has rarely been discussed from a multitasking perspective, but from a U&G theory perspective. Therefore, this study takes task-technology fit theory as the main framework, discusses podcast from the perspective of task and technology itself, and considers auditory characteristics and dominance characteristics as well as U&G theory to establish a research model.
The results of the study found: the characteristics of multitasking are fit to the characteristics of technological hearing, and the characteristics of multitasking have a greater positive impact than the characteristics of technological hearing; the influence of technology dominance characteristics on task technology fit is not established; the technological hearing is fit to the personal hearing, and the personal hearing has a greater impact; technology domination and personal domination are compatible, and technological domination has a greater impact; task technology fit, technology hearing fit, technology domination fit, U&G all positively affect the use intention of podcast. The task technology fit has the greatest impact, followed by U&G.
