Correlation coefficients between factor scores and the glottal shape and acoustic parameters. Coefficients based on cell means were calculated for two subsets of data: for prominence the soft and loud items were excluded; for vocal effort the unfocused and the weak items were excluded. Only significant coefficients (p<0.05) are shown here. Highly significant coefficients are printed in bold.
