Perceived spatial separation of speech and interference significantly improves speech recognition. This benefit holds even when the interfering speech is not fully intelligible.

Area of Science:

  • Auditory perception
  • Speech processing
  • Psychoacoustics

Background:

  • Understanding speech in noisy environments is challenging.
  • Spatial separation of sound sources can aid speech intelligibility.

Purpose of the Study:

  • To investigate how perceived spatial separation between target speech and interfering speech affects speech recognition.
  • To determine if this benefit extends to non-intelligible interfering speech.

Main Methods:

  • Three experiments were conducted using grammatically correct, nonmeaningful sentences as target speech.
  • Interference conditions included same-location (F-F) and spatially separated (F-RF) female talkers, leveraging the precedence effect.
  • Noise modulated by masker envelopes was used in a control experiment.

Main Results:

  • Sizable improvements in speech recognition were observed when interference was spatially separated (F-RF) compared to co-located (F-F).
  • This advantage was present for both single- and two-talker interference.
  • No benefit of spatial separation was found when interference was modulated noise.

Conclusions:

  • Perceived spatial separation of speech and interference enhances speech recognition.
  • The benefit of spatial separation is robust and does not require the interfering speech to be fully intelligible.
