Inclusion criteria

Inclusion criteria: Native speakers of German Between 21 and 39 years of age

Exclusion criteria: No language, speech (voice) or hearing disorders per self-report No hoarseness per auditory-perceptual screening performed by the PI . Overall voice quality rating G < 1 per GRBAS scale (Hirano, 1981).

Design outcomes

Primary

MeasureTime frame
We expect that at least one sentence for each target voiceless consonant will be moderately variable and have a mean token-level standard deviation below 0.6 semitones consistent with the English sentence validation.

Secondary

MeasureTime frame
Additionally, we expect the uniform utterances to have a mean token-level standard deviation below 0.5 semitones.
