According to the current oral training and necessity of the hearing impaired people, this study would develop mobile based tone training software for them. The withdrawal design (A-B-A design) of single-subject research designs has been applied for this study. The subjects of study are 4 hearing impaired university students. The software training has been applied for 3 successive days of baseline phase, 5 days of intervention phase and 3 days of maintenance phase. The result shows that: (1) the average level difference of the 4 subjects from baseline phase to intervention phase is +17.85 (subject A is +25.8%, subject B is +12.4%, subject C is +23.4%, and subject D is +9.8%). This shows that there has been positive effect to tone articulation of the 4 subjects. (2) The overlapped percentage of the 4 subjects from intervention phase to maintenance phase is 74.75% (subject A is 66%, subject B is 100%, subject C is 100%, and subject D is 33%). This shows that there has been maintenance effect for the tone articulation of the 4 subjects. (3) According to the result of the experiment, it has been verified that combining ocular feedback approach and mobile based software for oral training of the hearing impaired people have certain effects and prospects.
