Summary
Delayed auditory feedback (DAF) alters speech patterns. New measures analyzing pause and vocalization durations reveal individual speech variations under DAF, offering insights beyond traditional metrics.
Area of Science:
- Speech Science
- Auditory Feedback Research
- Phonetics
Background:
- Traditional speech analysis under delayed auditory feedback (DAF) relies on gross measures like reading time and pause duration.
- These measures offer limited insight into the nuanced changes in speech production caused by DAF.
Purpose of the Study:
- To investigate novel descriptive measures for analyzing speech alterations under DAF.
- To assess the utility of these measures in capturing individual speech performance variations.
Main Methods:
- Utilized an analog-to-digital converter to record speech.
- Analyzed 11 descriptive measures derived from pause and vocalization duration distributions.
- Compared speech patterns under normal conditions versus DAF conditions.
Main Results:
- Identified 11 distinct measures reflecting speech changes under DAF.
- Observed variations in individual speech performance consistent with subjective assessments.
- Demonstrated that these measures capture more detailed speech dynamics than gross measures.
Conclusions:
- The newly developed measures provide a more granular analysis of speech under DAF.
- Further research is needed to correlate these measures with subject, task, and environmental variables.
- These detailed measures hold potential for a deeper understanding of DAF effects on speech.
