Fig 2.
Number of studies and percentage of studies reporting a relationship between acoustic features and anxiety visualized using SRplot [48].
The size of the balloons indicates the number of studies examining each acoustic correlate. The color represents the percentage of studies reporting a relationship, with darker colors indicating a higher proportion of findings supporting an association between the acoustic feature and anxiety.
