從語音分布、連讀、押韻、音節結構等四種不同的角度來檢討閩南語喉塞音尾的性質，我們認為-?只不過是一種聲調短促的微性，而不是一種輔音。若進一步觀察其他漢語方言，如吳語、福州、南昌等各方言，似乎也可以作類似的處理和解釋。至於所有的漢語方言，甚至整個漢藏語系的語言，是否都可以作相同的處理和解釋，就有待進一步的研究了。

Based on phonetic distribution, connected speech, rhyming, and syllable structure, it is concluded in this paper that the syllable final -? in Southern Min dialects is a tone feature rather than a true consonant. The same interpretation seems to hold true for other Chinese dialects such as the Wu, Fujou and Nanchang dialects. It is suggested that we make further studies and look into the nature of -? in all other Chinese dialects and Sino-Tibetan languages.
