Fig 1.
Individual participant convergence patterns.
Each graph plots for each participant (one per row) the difference in semitones between the accompanist voice mean F0 (represented by the filled circles at zero) and (i) the participant’s mean F0 at solo reading (shown in the filled triangles) and (ii) the participant’s mean F0 at synchronous speech (shown in the empty triangles). Symbol colour represents whether each participant demonstrated significant convergence, divergence, or no change in their F0 between solo reading and synchronous speech, as determined using one-sample t-tests on their F0 change values (see Table 1). The three conditions (high F0, low F0 and extra-low F0) are plotted on separate graphs (A, B and C).

Frequencies of convergers, divergers and non-convergers (no change in F0) in high, low and extra-low F0 groups from Experiment 1.
Fig 2.
F0 change across trials in high, low and extra-low conditions.
Graph shows average change in F0 from solo reading baseline to synchronous speech (in semitones) for each trial of the task, averaged across participants in high, low and extra-low conditions. Shaded areas around lines indicate standard error.
Fig 3.
Average F0 change in high, low and extra-low conditions.
Graph shows average change in F0 from solo reading baseline to synchronous speech (in semitones) averaged across trials for participants in the three conditions of Experiment 1. Dots indicate individual participant averages, thick line indicates group means, boxes indicate standard errors.

Individual participant convergence patterns.
Each graph plots for each participant (one per row) the difference in semitones between the accompanist voice mean F0 (represented by the filled circles at zero) and (i) the participant’s mean F0 at solo reading (shown in the filled triangles) and (ii) the participant’s mean F0 at synchronous speech (shown in the empty triangles). Symbol colour represents whether each participant demonstrated significant convergence, divergence, or no change in their F0 between solo reading and synchronous speech, as determined using one-sample t-tests on their F0 change values (see Table 2). The three conditions (audiovisual, audio-only and visual-only) are plotted on separate graphs (A, B and C).

Fig 5.
F0 change across trials in audio, visual and audiovisual conditions.
Graph shows average change in F0 from solo reading baseline to synchronous speech (in semitones) for each trial of the task, averaged across participants in each of the three conditions of Experiment 2. Shaded areas around lines indicate standard error.

Average F0 change in visual, audio and audiovisual conditions.
Graph shows average change in F0 from solo reading baseline to synchronous speech (in semitones) averaged across trials for participants in the three conditions of Experiment 2. Dots indicate individual participant averages, thick line indicates group means, boxes indicate standard errors.
