Distributions of prosodic interval sizes in Tamil and English speech expressing different emotions.

<p>(A) Overlays of the average distributions of prosodic interval sizes in positive/excited (red) and negative/subdued (blue) Tamil speech (purple shows overlap). The top and bottom panels show data for the monologue and bi-syllabic recordings respectively. Insets compare the mean percentages of prosodic intervals smaller and larger than a major second (dashed lines separate these groups). Error bars indicate ±2 <i>SEM</i>. Asterisks indicate statistically significant differences between the underlying distributions (*<i>P</i><0.05; Mann-Whitney <i>U</i>-tests; see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031942#pone.0031942.s004" target="_blank">Figure S4</a> for complete statistics). (B) Same as (A), but for English speech.
