二十一世紀是個充滿跨國界活動的時代，如何有效率地進行溝通成為一個重要的議題。拜資訊科技之賜，電子郵件、行動電話讓人們的溝通更加容易，然而在溝通漸趨頻繁之後，如何讓溝通成本有效降低變成另一個重點，而近年來興起的網路電話（Voice over IP；VoIP）就是最佳的解決方案。
由於網路電話屬於一創新科技，本研究將引用科技接受模型（Technology Acceptance Model；TAM），輔以其他相關的理論擴展TAM的實用性。研究目的為探討影響個人接受網路電話之因素，並試圖找出影響個人行為意圖幾個較重要的變數。針對網路電話特性，擷取相關文獻研究構面，選出「知覺使用者人數」、「個人知覺效能」、「個人創新性」以及「系統可靠性」做為外部變數，並考量創新擴散理論（Innovation Diffusion Theory；IDT）其中的「相容性」以及網路電話的「價格」因素，一併納入研究架構中討論。
本研究第一階段先施以前測，建立起具備信、效度的問卷量表；第二階段正式問卷發放，共回收有效問卷521份，其中實際使用過網路電話的人數為292人。獲得之資料以SPSS 13.0 for Windows統計軟體進行徑路分析以驗證假說，此外，亦採取獨立樣本t檢定，檢定軟體與硬體網路電話兩種不同通話原理，是否造成個人在TAM 研究變數上的知覺程度有所差異。重要發現節錄如下：
1. 假說：「知覺自我效能對個人採用網路電話的知覺有用性有正向影響」，經驗證後發現假說並不成立。
2. 影響「行為意圖」與「態度」的最主要因素為「知覺有用性」；影響「行為意圖」的次重要因素為「知覺使用者人數」，「態度」方面則是「相容性」。影響「知覺有用性」的最主要因素為「相容性」；「知覺易用性」方面則是「知覺使用者人數」。
3. 軟體與硬體網路電話在「相容性」與「系統可靠性」兩個變數上有所差異，而且都是硬體網路電話的分數大於軟體網路電話。
最後將根據研究發現，提供策略性的建議供業界做為參考，並在學術貢獻上略盡棉薄之力。

In recent times, people travel on business or for pleasure more often than before. How to communicate efficiently with each other has become an important issue. The rapid develop- -ment of technologies such as e-mail and mobile phone make people communicate easily. However, while communicates getting more and more frequently, how to reduce communi- -cation cost turns into another key point. And we think the best solution is VoIP.
This article focuses on examining what factors could influence individual on acceptance of VoIP. Since VoIP is an innovative technology, we use Technology Acceptance Model as a theoretical foundation to explore the acceptance of VoIP. The study also adds what are argued to be key constructs such as Perceived of user number, Personal Self-efficacy, Personal Inno- -vativeness, and System Reliability to be the external variables of TAM. Besides, it considers the Compatibility characteristic select form Innovation Diffusion Theory and Price factor of VoIP.
The research analysis is presented in two stages. First, develop a questionnaire which has reliability and validity by pilot test. Second, a web-based questionnaire is designed. We ask users of on-line boards in the communication, computer, and hardware/software. In total, 521 replies were collected and 292 replies are actual users of VoIP. For the purpose, we conduct both Pearson Correlate Coefficient and Path Analysis by statistics software in order to verify the hypotheses. And individual t-test is processed to examine whether any difference between software/hardware VoIP in variables of TAM. There are some interesting findings:
1. A hypothesis: “Personal Self-efficacy positively influences the Personal Useful- -ness of VoIP” is not supported.
2. PU is the main factor influencing BI and Att; Com is the main factor influencing PU; and PNOU is the main factor influencing PEOU.
3. Software/hardware VoIP have difference in Com and SR. In addition, the mean of both variables are hardware VoIP higher than software VoIP.
Through testing those hypotheses, we find which personal factors affecting acceptance of VoIP and how worthwhile are they. Hence, we can provide some strategic advices for enterprises as reference and make contribution to the academic circles as possible as we can.
