Speech Mapping with Live Voice Inputs
The screenshot on the left shows
the Live Speech Mapping (LSM)
window. The system was designed
to capture and display the human
voice in the ear canal, so we
recommend using the microphone
input and the peaks measurement.
Using the microphone allows
measurement of both the
professional’s voice and that of the
patient’s significant others.
To improve repeatability of
measurements, it is recommended
that the speaker read a standard
passage such as the “Rainbow
Passage” which is provided on
pg. 27.
NOTE
: The screen shot above shows the MedRx Modified Speech Spectrum (Canoe). It is also
possible to underlay DSL IO or NAL-NL2 targets on this screen. Click
Options
in the text
menu bar on the top of the screen to select and configure these underlays to meet the needs
of your practice.
Speech Mapping with Recorded Inputs
For those who prefer a recorded,
repeatable stimulus for Speech
Mapping, the software provides
several digital audio files. These are
accessed by Clicking the
File
button on the right and then
selecting the desired track from the
pull-down menu in the audio
player. Peak measurements are
recommended.
Once the desired track is selected, Click the
Start
button to begin measuring. A pure tone or
white noise will be presented and once it reaches the selected input level with the slide bar,
the chosen track will play. When enough data is collected, Click the
Stop
button to stop the
recording and capture calibration measurement.
