Summary

The Speech Perception in Noise (SPIN) and Griffiths Modified Rhyme Test (GMRT) showed similar effectiveness for Navy divers. Context aids speech understanding, particularly with the SPIN test, in helium speech unscrambler (HSU) communication systems.

Area of Science:

  • Audiology
  • Speech Science
  • Diving Physiology

Background:

  • Underwater communication systems for Navy divers present unique challenges due to helium speech.
  • Evaluating the intelligibility of speech in noisy, helium-rich environments is crucial for diver safety and operational effectiveness.
  • Existing speech perception tests may vary in their suitability for assessing communication in these specialized conditions.

Purpose of the Study:

  • To compare the effectiveness of the Speech Perception in Noise (SPIN) test and the Griffiths Version of the Modified Rhyme Test (GMRT).
  • To assess Navy divers' speech understanding through communication systems with different helium speech unscramblers (HSUs).
  • To evaluate the influence of listening conditions (taped vs. live-voice) on speech perception test performance.

Main Methods:

Related Experiment Videos

  • Participants included Navy divers during saturation dives and a control group of non-divers.
  • Digital audio recordings of stimuli were used, simulating diver-to-diver and topside-to-diver communication.
  • Performance was measured using mean percent correct scores on both SPIN and GMRT lists across two listening conditions.

Main Results:

  • Mean correct scores on SPIN and GMRT were nearly identical across tested conditions.
  • Listeners performed better in the topside-diver (taped) condition compared to the diver-diver (live-voice) condition.
  • SPIN test errors were predominantly on low-predictability, context-poor items, indicating context's importance.

Conclusions:

  • Both SPIN and GMRT are comparably effective for assessing speech understanding in Navy divers using HSU systems.
  • The listening condition significantly impacts speech perception scores, with taped, topside-diver communication yielding better results.
  • Contextual information plays a vital role in speech perception, especially for the SPIN test, in these communication scenarios.
