INTRODUCTION
Hunter et al (2020) defined vocal demand both in terms of the scenario description and the vocal content required to satisfy that communicative scenario. The vocal demand response was defined as the individual manner in which speakers use their voice in an attempt to meet a perceived vocal demand. This response can be described in terms of subjective and objective qualities combined with physiological phonation within the context of a vocal demand.
METHODS
A bibliometric analysis using the OpenAlex database was performed. The query term was "vocal demand". Following the identification phase, all records were downloaded in .ris format and uploaded to Rayyan. Then, duplicates were eliminated, and titles and abstracts were screened. As the final step, a term co-occurrence map was created using VOSviewer (version 1.6.20).
RESULTS
The initial search in OpenAlex retrieved 283 records. After duplicates deletion and initial screening of titles and abstracts, 141 records were excluded. Consequently, 142 publications were included for bibliometric analysis. Four keyword co-occurrence clusters were identified. The first cluster included terms focused on vocal demand. The second cluster included terms focused on vocal effort. The third cluster included terms focused on treatment. The fourth cluster included terms focused on vocal demand response.
CONCLUSIONS
The results of this bibliometric analysis suggest an emerging recognition of “vocal demand response” as the individualized nature of vocal system responses to external demands.
The modest number of publications suggests that vocal demand and vocal demand response remain an evolving area of inquiry requiring further empirical investigation and theoretical refinement.
