Summary

Women exhibit higher speech intelligibility than men, with significant acoustic differences observed. However, correlations between speech intelligibility and acoustic measures were low, necessitating further research.

Area of Science:

  • Speech Science
  • Acoustic Phonetics
  • Prosthodontics

Background:

  • Speech intelligibility is crucial for communication.
  • Objective acoustic parameters are increasingly used to analyze voice characteristics.
  • Understanding sex-based differences in speech is important for various applications, including prosthodontics.

Purpose of the Study:

  • Compare speech intelligibility between men and women.
  • Validate objective acoustic parameters for speech intelligibility assessment.
  • Establish baseline data for future prosthodontic research.

Main Methods:

  • Twenty men and women participated.
  • Speech intelligibility tests were conducted by three speech pathologists.
  • Acoustic analyses included fundamental frequency, formant frequencies, vowel space area, and dispersion.

Main Results:

  • Women demonstrated significantly higher speech intelligibility scores compared to men.
  • Most acoustic parameters showed significant differences between sexes.
  • Correlations between speech intelligibility scores and acoustic parameters were low.

Conclusions:

  • Speech intelligibility tests and acoustic parameters effectively differentiate male and female voices.
  • These parameters may be valuable in maxillofacial prosthodontics research.
  • Further investigation is required to clarify the relationship between speech intelligibility and acoustic measures.
