Data Results for Affricates: /ȴ/ & /ȷ /
Figure 3 illustrates CP’s performance during data probes as the percent <strong>of</strong> affricates
/ȴ, ȷ/ correctly produced in carrier phrases. Data were charted over time during baseline,
treatment, and post treatment phases. Pre treatment data probes indicated that CP
produced /ds/, /d/, and /Ȉ / sounds in place <strong>of</strong> / ȴ / and /ts/, /d/, /t/, and /s/ sounds in place
<strong>of</strong> / ȷ / phonemes.
CP demonstrated levels <strong>of</strong> performance on speech probes during baseline sessions (1
through 19) alternating between 0 and 60% accuracy <strong>of</strong> /ȴ, ȷ/ phonemes. Baseline speech
probes show some indication <strong>of</strong> improved speech production <strong>of</strong> / ȴ / and / ȷ / phonemes
in carrier phrases before treatment for the sounds had begun. This may have been a result
<strong>of</strong> CP’s increased awareness and control <strong>of</strong> speech sounds and articulators acquired over
the course <strong>of</strong> 17 sessions. Sessions 20 through 37 include data probes gathered after
treatment had begun. Over the treatment period, CP’s accuracy fluctuated between 20%
and 100% for / ȴ / and / ȷ / phonemes in carrier phrases over sessions 20 through 37.
Post-Treatment Results for Affricates: /ȴ/ & /ȷ /
Post treatment results (sessions 38 through 40 in Figure 3) illustrate that CP’s correct
production <strong>of</strong> target phonemes /ȴ / and / ȷ / remained at or above 60% accuracy in
carrier phrases. Data results indicate that CP’s accurate production <strong>of</strong> / ȴ / and / ȷ /
phonemes increased over the course <strong>of</strong> 20 treatment sessions and was maintained
approximately 2 weeks after treatment ended.
