\caption{\label{1}Experimental results of speech pattern discovery in "audio only", "visual only", "feature fusion" and "decision fusion"}
\begin{tabular}{c|c|c|c|c}
\hline
 & Precision & Recall & F1-meature & Time\\
\hline
Audio only &   41.38\%  &   53.50\%      &  46.67\%     & 229.15s  \\
\hline
Visual only &   34.14\%  &   29.03\%      &  31.38\%     & 493.69s  \\
