Announcing 'Stammering Research' - Stammering Research - UCL

Stammering Research. Vol. 1.
The Pocket DAF/FAF Assistant
interface is simple and intuitive.
There are two gauge controls that are
responsible for setting Delay and
Frequency Shift. The Delay has the
range of 50 ms to 250 ms. The
Frequency Shift has the range of -10
to +10 which corresponds to +/- onehalf
octave. These intervals are
widely used in DAF/FAF speech
therapy.
The DAF/FAF Assistant
automatically saves configured
Delay and Frequency Shift settings
when you close the program and
restores these settings back when
you start the application.
The Start and Stop buttons turn the
sound playback on and off.
The Register button allows you to
enter your registration name and key.
When the software is registered this
button is hidden.
