A speaker’s portrait is 48x48 pixels in size. Spritesheets for a speaker should be multiples of 48 pixels to a side to ensure Chatty can sample frames properly.
Frames are counted in 48x48 pixel squares, starting from the top left and moving right and down the image. An example of frame numbering for a 144x144 pixel image is shown below.
