Validation of a Swiss German Language Test for Children

The aim of this study is to validate a Swiss German children's language test. Standard values for the speech intelligibility of Swiss German monosyllables and disyllables for children with normal hearing aged 4-6 years are recorded.

Treatment and study plan

Speech test

Diagnostic Test

The hearing screening ensures normal hearing before enrollment. The speech reception threshold for swiss german mono- and bisyllable words is determined in an adaptive procedure.

Other names: Hearing screening

Primary outcomes

  1. Speech reception threshold for monosyllabic words

    Time frame: Single visit at baseline

    Speech Reception Threshold (SRT) measured in decibel sound pressure level (dB SPL), with lower scores indicating better hearing

  2. Speech reception threshold for bisyllabic words

    Time frame: Single visit at baseline

    Speech Reception Threshold (SRT) measured in decibel sound pressure level (dB SPL), with lower scores indicating better hearing

Secondary outcomes

  1. Speech reception threshold in noise for monosyllabic words

    Time frame: Single visit at baseline

    Speech Reception Threshold (SRT) measured in decibel signal-to-noise ratio (dB SNR) with lower scores indicating better hearing

  2. Speech reception threshold in noise for bisyllabic words

    Time frame: Single visit at baseline

    Speech Reception Threshold (SRT) measured in decibel signal-to-noise ratio (dB SNR) with lower scores indicating better hearing
