Naturally produced clear speech significantly improves listening for native speakers but offers minimal benefit to non-native listeners. Clear speech is tailored for native language users, not those learning a new language.

Area of Science:

  • Speech Perception
  • Auditory Neuroscience
  • Second Language Acquisition

Background:

  • Previous research indicates clear speech enhances intelligibility for native and hearing-impaired listeners in noisy environments.
  • Clear speech involves slower articulation, increased pitch range, and precise consonant production.

Purpose of the Study:

  • To evaluate the effectiveness of naturally produced clear speech as an intelligibility enhancement strategy for non-native English listeners.
  • To compare the benefits of clear speech for non-native listeners versus native listeners.

Main Methods:

  • 32 non-native and 32 native English listeners participated.
  • Participants listened to English sentences produced in either conversational or clear speaking styles.
  • Stimuli were presented at two signal-to-noise ratios (-4 dB and -8 dB) by a male and female talker.

Main Results:

  • Native listeners showed a substantial improvement in intelligibility with clear speech (approx. 16 rau units).
  • Non-native listeners exhibited a significantly smaller benefit from clear speech (approx. 5 rau units).

Conclusions:

  • Naturally produced clear speech is less effective for non-native listeners compared to native listeners.
  • The benefits of clear speech are limited for non-native listeners due to its orientation towards native phonological and prosodic patterns.
