The accuracy of the predictive generalized mixed-effect model is 70.9%–71.4%. Significant differences in the effect sizes and directions are observed between female and male subgroups. The greater the severity of mania in males, the louder (&lt;i&gt;β&lt;/i&gt; = 1.6) and higher the tone of voice (&lt;i&gt;β&lt;/i&gt; = 0.71), more clearly (&lt;i&gt;β&lt;/i&gt; = 1.35), and more sharply they speak (&lt;i&gt;β&lt;/i&gt; = 0.95), and their conversations are longer (&lt;i&gt;β&lt;/i&gt; = 1.64). For females, the observations are either exactly the opposite—the greater the severity of mania, the quieter (&lt;i&gt;β =&lt;/i&gt; −0.27) and lower the tone of voice (&lt;i&gt;β&lt;/i&gt; = −0.21) and less clearly (&lt;i&gt;β&lt;/i&gt; = −0.25) they speak — or no correlations are found (length of speech). On the other hand, the greater the severity of bipolar depression in males, the quieter (&lt;i&gt;β&lt;/i&gt; = −1.07) and less clearly they speak (&lt;i&gt;β&lt;/i&gt; = −1.00).
