A voice therapy program using pushing exercises to correct glottal inc
ompetence is described. The program utilizes various types of instrume
ntation to determine whether or not a given patient is likely to benef
it from the treatment. The program also provides feedback of target vo
ices. Three cases with incomplete glottal closure and subsequent vocal
dysphonia characterized by an asthenic breathy quality are used to il
lustrate the program. Details of the program, termination criteria, an
d problems and precautions learned from treating 29 patients over a 3-
year period are presented.
