Characteristics of talkers, listeners, and their surroundings can make speech more or less intelligible. To increase intelligibility, talkers may employ hyperarticulation – the exaggeration of speech sounds. Currently, I’m investigating affrication in English stops as a potential consequence of hyperarticulation. This affrication may be limited to certain segmental contexts or prosodic positions. My research seeks to answer: 1) what are the acoustic properties of this affrication 2) in what specific environments is it produced, and 3) do talkers spontaneously produce it under suboptimal conditions. Answers to these questions serve to enhance our understanding of talker-based methods for increasing intelligibility in speech.
