Auditory Perception

939
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Summary
This summary is machine-generated.

The Filter-bank (FB) scheme, using four spectral components, improved consonant perception in noise compared to the zero-crossing (ZC) scheme with two spectral components in normal-hearing subjects.

Area of Science:

  • Audiology and Speech Sciences
  • Signal Processing
  • Psychoacoustics

Background:

  • Speech processing schemes are crucial for understanding speech perception, particularly for individuals with hearing impairments.
  • Real-time laboratory speech processors enable controlled studies on how spectral information affects auditory perception.
  • Comparing different spectral component extraction methods is essential for optimizing speech intelligibility.

Purpose of the Study:

  • To compare the efficacy of two distinct speech processing schemes, zero-crossing (ZC) and Filter-bank (FB), in a real-time laboratory setting.
  • To evaluate the impact of the number of spectral components (two vs. four) on speech perception in normal-hearing individuals.
  • To assess performance differences in vowel and consonant perception, as well as word recognition and speech tracking.

Main Methods:

  • Implemented two real-time speech processing schemes: ZC (two spectral components) and FB (four spectral components).
  • Conducted perceptual studies with 4 normal-hearing subjects, employing a within-subjects design with counterbalanced training and testing.
  • Measured vowel perception, consonant perception in noise (5-20 dB SNR), open-set CNC word recognition, and speech tracking scores.

Main Results:

  • Vowel perception performance was comparable between the ZC and FB schemes across all subjects.
  • Consonant perception in noise showed significantly higher accuracy for the FB scheme compared to the ZC scheme.
  • Open-set CNC word recognition and speech tracking scores were also superior with the FB scheme.

Conclusions:

  • The Filter-bank (FB) scheme, utilizing more spectral information (four components), offers enhanced consonant perception in noise over the zero-crossing (ZC) scheme (two components).
  • The FB scheme demonstrates superior performance in complex speech recognition tasks like CNC words and speech tracking.
  • These findings suggest that processing more spectral detail is beneficial for speech intelligibility, especially in noisy environments.
