Abstract

This study presents a bibliometric analysis of 500 publications (2010–2025) on bone-conducted voice (BCV) technologies, highlighting their evolution from medical to educational applications, particularly in articulation training. Using performance analysis, co-citation and keyword mapping, content review, and gap assessment, we found an 8.3% annual growth rate and identified five intellectual clusters, with voice-mixing technologies as an emerging field. Teacher-student voice synchronization was notably underrepresented (coverage adequacy 2.6/10; 8.2% of studies). Research was concentrated in North America and Europe, with East Asia showing faster growth. Experimental studies demonstrated higher methodological rigor (3.8/5) than observational ones (3.2/5). The findings reveal a substantial gap in teacher-student audio blending research and propose a roadmap for integrating BCV with air-conducted feedback to enhance speech recognition, production, and attention in children with speech sound disorders.
