PowerPoint

Hi Simona

Thank you for your question; and welcome to the forum.

You can draw a speech bubble shape from the Drawing toolbar in PowerPoint.

Make sure the Drawing Toolbar is turned on (View - Toolbars - Drawing).

Go to AutoShapes on the Drawing Toolbar and you will find several different speech bubble shapes under Callouts.

Select the shape you wish to use, and diagionally drag your left mouse on the slide to draw the shape onto the slide.

Kind regards
Amanda
