Schedule 73. StuTS

That auditory feedback plays a significant role in online speech monitoring and thus in speech production, has been shown using real-time auditory feedback perturbation experiments. When auditory feedback perturbation is applied, how participants hear themselves is altered, which creates a mismatch between the participants’ expectations of auditory feedback and the actual feedback they are presented with. This kind of perturbation can be applied to different properties of speech, i.e., spectral properties such as formants but also temporal properties. Previous studies on temporal auditory feedback perturbation (e.g., Oschkinat & Hoole 2020, 2022 using German real-words, Karlin et al. 2021, Karin & Parrell 2022 using English real-words) have shown that when confronted with perturbed feedback participants alter their production to compensate in the opposite direction, which means that a shortened sound is expected to be lengthened, while a lengthened sound shortened. However, the exact nature of compensation is dependent of several factors, e.g., language-specific phonetic contrasts (Niziolek & Guenther 2013, Karlin & Parrell 2022), syllable position (Oschkinat & Hoole 2020), rhythmic ability and auditory acuity (Oschkinat et al. 2022), as well as impairments such as stuttering (Frankford et al. 2022).

The present study investigates the effect of temporal auditory feedback perturbation on Quebec French CVC syllables using the targets [sut] and [tus]. In the first condition (onset condition), the onset consonant [s] is stretched, while the vowel [u] is shortened. In the second condition (coda condition) the vowel [u] is stretched, while the coda consonant [s] is shortened. Because no final results can be presented yet, the talk will mainly focus on the study design and the method as well as speculate on how the temporal characteristics of Quebec French will possibly influence the results.
