Abstract This study investigated the role of prevoicing, breathy-voicing, and plain-aspiration in the perception of the voiced-aspirated stop category in Bangla. 31 native speakers of Bangla undertook two different perception experiments where they had to identify what stop category they can hear in forced-choice MCQ tasks. Each experiment presented 25 stimuli (repeated 3 times) that were artificially manipulated; stimuli in Experiment-1 were manipulated for the duration of prevoicing and breathy-interval, while stimuli in Experiment-2 were manipulated for the duration of prevoicing and plain-aspiration. A total of 4650 response tokens were collected in two experiments. Results revealed that a prevoicing interval of about 40ms and a breathy interval of about 20–40 ms are required for the perception of voiced-aspirates. In addition, listeners showed a clear preference for breathy-voicing over plain-aspiration when categorizing sounds as voiced-aspirated stop, indicating that breathy-voicing is perceived to be better associated with voiced-aspirates. Implications for the general phonetics of voiced-aspirates are discussed in the light of the results.

孟加拉语中预声、呼吸声和送气在感知呼吸声塞音中的作用

摘要 本研究调查了在孟加拉语中浊送气塞音类别感知中的前置声、呼吸声和普通送气的作用。31 位以孟加拉语为母语的人进行了两项不同的感知实验，他们必须确定他们在强制选择 MCQ 任务中可以听到的停止类别。每个实验呈现 25 个刺激（重复 3 次），这些刺激是人工操纵的；实验 1 中的刺激在发音和呼吸间隔期间被操纵，而实验 2 中的刺激在发音和普通吸气期间被操纵。在两个实验中总共收集了 4650 个响应令牌。结果表明，感知浊音吸气需要大约 40 毫秒的发声间隔和大约 20-40 毫秒的呼吸间隔。此外，在将声音归类为浊送气塞时，听众表现出明显偏爱呼吸发声而不是平送气音，这表明呼吸发声被认为与浊送气音更好地相关联。根据结果​​讨论了对浊送气的一般语音的影响。
