Indeed, the major finding of this study, that bimodal presentation (text with voice) had a hindering, rather than a facilitative, effect on learning performance was not in line with dual-coding theory, which formed the theoretical premise of this research.‘ http://www.carleton.ca/hotlab/hottopics/Articles/VoiceandText.html
