Summary
This study introduces the Horii Oral-Nasal Coupling Index (HONC), a new measure for assessing oral-nasal coupling. HONC utilizes accelerometer data to quantify the ratio of nasal to vocal amplitude, offering insights into speech production.
Area of Science:
- Speech science
- Biomedical engineering
- Acoustics
Background:
- Assessing oral-nasal coupling is crucial for understanding speech production.
- Existing methods may have limitations in real-time or non-invasive measurement.
Purpose of the Study:
- To introduce and describe the Horii Oral-Nasal Coupling Index (HONC).
- To present a novel method for quantifying oral-nasal coupling using accelerometry.
Main Methods:
- Development of the Horii Oral-Nasal Coupling Index (HONC).
- Utilizing accelerometers placed on the nose and neck.
- Calculating HONC as the ratio of nasal amplitude to vocal amplitude.
Main Results:
- Preliminary data suggests HONC is a viable measure of oral-nasal coupling.
- The index is derived from easily obtainable accelerometer signals.
- Discussion of the advantages of the HONC method.
Conclusions:
- The Horii Oral-Nasal Coupling Index (HONC) offers a promising new tool for speech analysis.
- Accelerometry provides a practical approach for measuring oral-nasal coupling.
- Further research will explore the clinical and research applications of HONC.
