摘要

由於語音辨識技術日趨成熟，通訊產品功能愈來愈豐富，對中高齡者而言提高操作的複雜度，常常無法順利使用這類的通訊產品。
語音辨識這樣自然、直接的操作介面，理論上應該能幫助中高齡者容易操作手機，但目前似乎沒有顯著的效果，本研究主要探討語音聲控介面沒有被廣泛使用的原因，評估其使用性，並提出設計原則。
研究結果發現，中高齡者沒有使用語音聲控介面的可能原因，不知道語音辨識技術己經應用在手機介面上，中高齡者很少有意願主動去瞭解新技術與科技。除了指令記憶的問題，語音聲控介面比傳統按鍵介面具有較高的使用性。
根據中高齡者使用語音聲控介面的困難點，提出設計原則如下：1. 語音功能按鍵可以獨立設立，以方便使用。2. 關鍵指令應該統一。3. 增加語音的資料庫，讓功能指令愈口語愈好。4. 語音聲控介面應該獨立操作，不要結合傳統按鍵的介面。

Because of the progress of communication technology, sound identification has reached its maturity and it brings communication products with much more divergent contents. For intermediate-age and advance-age users, the enhanced operation complexity usually cannot make the said users comprehensively and smoothly operate communication products.
A natural and direct operation interface like sound identification, theoretically, can help intermediate-age and advance-age users operate cell phones more comprehensively and conveniently. However, till now, there seems to be no significant effect like that happening. This research is mainly aimed to explore the reason why the said sound control interface cannot be widely applied so far and evaluate its applicability with our design principles proposed.
From research results, we find the possible reasons that no intermediate-age and advance-age user adopting sound identification technology is because they never know that the said sound identification technology has been designed in cell phones already. Actually, there are few intermediate-age and advance-age users willing to understand novel techniques and technology aggressively. Except the problems about command memory, the sound control interface is really featured with higher applicability than that of conventional key-in interface.
Based on the difficulties for intermediate-age and advance-age users to adopt sound control interface, we hereby propose the design principles as below:
1. The sound control function keys can be designed with the stand-alone style for operation convenience.
2. The critical commands shall be unifiedly arranged.
3. It is required to enhance the sound control database with better commanding operation triggered by frequently-used daily vocabulary.
4. The sound control interface shall be operated independently of no combination with conventional key-in interfaces.
