4715. Parliamentary Recordings as a Resource for Speech Research in Less- Resourced Languages (FA2026/956)

Nikola Ljubešić (Jožef Stefan Institute)

A20 Speech

Parliamentary recordings are a well-known resource for obtaining large-scale data for automatic speech recognition. In this contribution, we argue for a much broader use of parliamentary recordings and their accompanying official transcripts, rich speaker metadata, and generally non-problematic privacy and copyright status, especially in the context of less-resourced languages. Beyond speech...

4599. Charisma in a few seconds: Prosodic Prominence and the Perception of Vocal Charisma in Short Conversational Speech (FA2026/770)

A20 Speech

This study examines the relationship between prosodic prominence and perceived charisma in conversational speech. We conducted a perception experiment with 92 speech stimuli drawn from a corpus of spontaneous interactions and obtained ratings of charisma, like-ability, self-confidence, and passion from 30 listeners. First, we analyzed the interrelations among these perceptual dimensions and...

4598. Effect of hearing aid amplification on supra-segmental acoustic features for speech production (FA2026/637)

A20 Speech

Speech production is continuously adjusted by auditory and somatosensory feedback loops, allowing speakers to monitor and adapt their vocal output based on multimodal sensory input. In hearing-impaired speakers, a degraded auditory feedback loop results in altered supra-segmental characteristics, such as increased vocal intensity, slower articulation rates, and elevated fundamental frequency....

4600. The company we keep: Prosodic similarity within and across organizations (FA2026/164)

Oliver Niebuhr (University of Southern Denmark)

A20 Speech

Do speakers from different organizations sound systematically different? Using the COMPASS corpus of more than 500 L2 English business presentations from 18 companies across 10 industry sectors, we analyzed 28 acoustic-prosodic features of speaking style. Linear discriminant analyses and MANOVA reveal clear non-random clustering of prosodic patterns. Both company membership and industry-sector...

4601. Subjective and objective employability for degraded speech in video-mediated job interviews (FA2026/211)

Julia Schütze (UniDistance Suisse)

A20 Speech

The quality of audio transmission in video conferencing systems can influence not only speech perceptionbut also higher-level social judgments in communication contexts such as hiring decisions following jobinterviews. The present study investigated how degradations in speech quality affect perceived employability and whether objective audio quality models capture these effects.The audio...

4602. The Audience Reactor: An Embodied Sparring Partner for Public- Speaking Training (FA2026/206)

Idun Elvira Christensen (University of Southern Denmark)

A20 Speech

Public-speaking skills comprise a set of interrelatedabilities, including vocal delivery, linguistic appropri-ateness, and audience-oriented communication. How-ever, this multidimensionality makes it challenging toprovide individualized, high-quality feedback, particu-larly within time-constrained curricula and in contextswhere instructors lack specialized training in oral com-munication...
