| Abstract(in English) | In order to investigate speechmodifications under reverberant environments, and relationships between themodifications and speech intelligibility in reverberant environments, acoustic analyses were performed for vowel parts produced by a male speaker in 4 reverberant environments. The results showed that F1 and F2 frequencies shift in addition to decrease/increase speech level, lengthening of duration depending on the reverberant environments. The F1 and F2 shifting showed different pattern by vowel type. It indicates that acoustic/articulatory features of each vowel became clearer. It is suggested that speech produced under reverberant environments is hyper-articulated speech (i.e., clear speech) with less coarticulation and steeper formant transitions which can contribute to speech intelligibility in reverberant environments. |
