A new Danish speech material, DANTALE, offers comprehensive tools for speech audiometry, including digit triplets, word lists, and continuous speech for various audiological assessments.

Area of Science:

  • Audiology
  • Speech Science
  • Hearing Research

Background:

  • Current audiological practices require standardized and validated speech materials.
  • Existing speech audiometry tools may not fully meet the specific needs of Danish hearing centers.
  • Digital recording and advanced signal processing enable more precise audiological measurements.

Purpose of the Study:

  • To introduce and describe DANTALE, a new digital speech material for clinical and experimental speech audiometry in Denmark.
  • To provide audiological professionals with a comprehensive resource for assessing speech reception threshold, discrimination, and loudness perception.
  • To offer a validated tool for evaluating hearing aid fitting and auditory processing abilities.

Main Methods:

  • Digital recording of speech signals and masking noise onto a compact disc (CD).

Related Experiment Videos

  • Inclusion of digit triplets for speech reception threshold (SRT) measurement.
  • Development of adult and child-specific monosyllabic word lists for discrimination score (DS) assessment.
  • Provision of continuous speech segments for most comfortable loudness level (MCL) and hearing aid fitting evaluations.
  • Generation of an amplitude-modulated, speech-shaped noise signal simulating a 4-person speech babble for frequency and temporal resolution assessment.
  • Detailed description of the speech material, including long-term power and modulation spectra.
  • Main Results:

    • The DANTALE material comprises digit triplets, adult and child word lists, and continuous speech segments.
    • Adult word lists are phonetically and visually equalized; child lists use minimal pairs.
    • The masking noise simulates speech babble to assess frequency selectivity and temporal resolution.
    • Calibration signals are included on the CD for accurate measurement setup.

    Conclusions:

    • DANTALE is a novel, digitally recorded speech material designed to meet current audiological requirements in Danish hearing centers.
    • The comprehensive nature of DANTALE supports various audiological assessments, from basic thresholds to complex auditory processing.
    • This material provides a standardized and validated tool for enhancing speech audiometry practices and research.
