Summary

Wearing a face mask during speech production alters tongue movements. Specifically, masks cause changes in linguopalatal contact for certain consonants, suggesting articulatory compensation strategies.

Area of Science:

  • Speech Science
  • Articulatory Phonetics
  • Human-Computer Interaction

Background:

  • Face masks are widely used, potentially impacting speech production.
  • Understanding articulatory changes is crucial for communication and assistive technologies.

Purpose of the Study:

  • To investigate how face masks affect linguopalatal contact during speech.
  • To identify specific changes in tongue-palate interactions with mask use.

Main Methods:

  • Electropalatography (EPG) was used to record linguopalatal contact.
  • Data were collected from five Catalan speakers producing specific consonants ([n], [n], [j]).
  • Speech samples were analyzed in both mask and non-mask conditions.

Main Results:

Related Experiment Videos

  • The alveolar stop [n] showed increased closure retraction when wearing a mask.
  • The alveolopalatal stop [n] and palatal approximant [j] exhibited increased dorsopalatal contact.
  • These changes are hypothesized to be compensatory strategies.

Conclusions:

  • Face mask use demonstrably alters linguopalatal contact during speech.
  • Speakers may employ compensatory mechanisms to maintain speech intelligibility.
  • Further research is needed to explore the full implications for speech perception and production.
