Pocket DAF/FAF Assistant for PDA can be used by people who have stuttering problem to control their speech fluency, increase their confidence level and develop carryover fluency when techniques are used on a regular basis. Delayed auditory feedback (DAF) delays your voice to your ears a fraction of a second. The application provides delay range from 50 to 250 milliseconds. The delay increment step is 10 milliseconds. A short delay ( 50-80 milliseconds) almost instantly reduces stuttering without changing the speech speaking rate. A longer delay (90-250 milliseconds) makes you stretch your vowels and talk slower. This can help with even severe stuttering, but requires training, mental effort, and may sound abnormal. Frequency Altered Feedback (FAF) shifts the pitch of your voice. The application provides the pitch shift in the range from one-half octave down to one-half octave up. The FAF enhances the effectiveness of the application when is used simultaneously with DAF. The application saves the configured settings when it is closed and restores them when it is restarted.

The application is compatible with Bluetooth (wireless) headsets on those Pocket PCs that support Bluetooth headset connections. Easy to install, easy to use.
