Systems and methods for authoring and modifying presentation conversation files are disclosed. Exemplary implementations may: receive, at a renderer module, voice files, visual effect files,
facial expression files, and / or mobility files; analyze, by the
language processor module, the voice files, the visual effect files, the
facial expression files, and / or mobility files follow guidelines of a multimodal
authoring system; generate, by the renderer module, one or more presentation conversation files based at least in part on the received voice files, visual effect files,
facial expression files, and / or mobility files; test, at an
automatic testing system, the one or more presentation conversation files to verify correct operation of a computing device that receives the one or more presentation conversation files as an input; and identify, by a multimodal review module, changes to be made to the voice input files, the visual effect files, the facial expression files, and / or the mobility files.
