This study investigated whether gradient speech change occurred in six participants with cleft palate ± lip undergoing intervention within a usage-based phonology framework (2/6 participants with speech distortions; 4/6 with pattern-based speech substitutions; combined total of 25 speech sounds targeted for intervention). Participants received weekly therapy in a hospital setting and were aged 10-27 years. Gradient speech change with target speech sounds was examined using EPG analysis, which was undertaken after every fifth session of therapy. The presence of gradient change was determined by visually examining EPG palatograms and EPG indices for target speech sounds across successive EPG test points. This study found gradient speech change occurred in 22/25 target sounds over the course of intervention. This gradient change occurred for both speech distortions and pattern-based speech substitutions. The remaining 3/25 target sounds showed categorical change. Usage-based phonology was suggested as a theory with potential for explaining gradient speech change, with both typical and atypical speech, and with speech distortions and pattern-based speech substitutions.
