Area of Science:

  • Speech-Language Pathology
  • Augmentative and Alternative Communication
  • Voice Disorders

Background:

  • Esophageal speech is a method for voice restoration after laryngectomy.
  • Intelligibility of esophageal speech can be a challenge, particularly for certain speech sounds.
  • Targeted practice may improve specific phonetic features in esophageal speech.

Purpose of the Study:

  • To investigate the effect of targeted practice on the intelligibility of esophageal speech.
  • To determine if practice focusing on words beginning with +BACK consonants improves intelligibility.
  • To compare gains for practiced (+BACK) versus less-practiced (-BACK) consonants.

Main Methods:

  • Seven esophageal speakers recorded speech intelligibility word lists.

Related Experiment Videos

  • Practice focused on words starting with +BACK consonants and clusters.
  • Recordings were assessed before and after an 8-session practice period.
  • Naive listeners evaluated the intelligibility of recorded speech samples.

    • Main Results:

    • Significant improvement in intelligibility for +BACK words from 84.1% to 90.6%.
    • Average gain of 0.81% per session for +BACK word practice.
    • Lower average gain of 0.46% for less-practiced -BACK items.

    Conclusions:

    • Targeted practice significantly enhances the intelligibility of esophageal speech for specific phonetic contexts.
    • The findings support the efficacy of focused speech therapy for improving consonant production in esophageal speakers.
    • The study provides quantifiable data on practice effects in esophageal voice users.
