Junctural contrasts in esophageal and normal speech
Journal of Speech and Hearing Research
|March 1, 1981
Summary
Both normal and esophageal speakers effectively use junctural contrasts in speech production. This study highlights the importance of clinical samples for understanding speech and language therapy, production, and perception.
Area of Science:
- Linguistics
- Speech-Language Pathology
- Auditory Perception
Background:
- Junctural contrasts are crucial for distinguishing meaning in spoken language.
- Esophageal speech presents unique challenges for producing and perceiving these contrasts.
Purpose of the Study:
- To assess the realization of junctural contrasts by individuals using esophageal speech compared to normal speakers.
- To investigate the impact of speaker type on the perception of speech juncture locus.
Main Methods:
- High-quality audio recordings of five ambiguous two-word phrases were collected from ten normal and ten esophageal speakers.
- Forty listeners evaluated the recordings using a Two Interval Forced Choice procedure to determine juncture perception.
Main Results:
- Both normal and esophageal speakers demonstrated effective realization of junctural contrasts.
- Significant differences in listeners' perception of juncture locus were observed based on speaker group and individual variations.
Conclusions:
- The study confirms that esophageal speech can effectively convey junctural contrasts.
- Findings underscore the value of clinical speech samples in advancing research in speech production, perception, and linguistic therapy.
