Motor Speech Disorder Assessment (MSDA)
Dysarthria and Apraxia
Motor Speech Disorders are known as
dysarthria or apraxia. Muscles of the mouth may become weak resulting in
a slow articulation movement after a stroke
or other brain injury or a brain damage results in having trouble
sequencing sounds in syllables and words.
Beside of other symptoms a person may experience a
slow rate of speech or changes in voice quality like hoarseness
and breathiness.
Changes in voice quality can be reliable
measured with the
lingWAVES Vospector (irregularity - hoarseness, noise - breathiness,
hoarseness - overall severity). The (maximum) rate of speech can be
determined with the Diadochokinetic Rate (DDK).
In the past DDK assessment was a time consuming work counting the number
of syllables spoken in a given time period.
lingWAVES DDK assessment
A quick DDK
assessment within seconds is now available with the
lingWAVES Motor Speech Disorder Assessment (MSDA)
using new speech technology.
Recorded and analyzed word
sequence. The calculation takes about 3 seconds on a recent Windows XP
or Vista PC. All results are clearly arranged and visible at a glance.
MSDA records a sequence of the word
“buttercup” with front, middle and back articulation during one air
stream / expiration. After selecting and starting the automatic
calculation the DDK rate and other useful measurement values (F0,
DDK jitter and SD, SNR, energy slope) are available within 2-5
seconds and are shown in an easy to interpret “green-to-red” result
window on the left. The colors of the measurement values show a gradual
normal-abnormal indication.
Because of the used
new speech technology alignment process of lingWAVES MSDA, the
program is also able to extract information about
each syllable occurring in the word sequence. Therefore MSDA can
measure and display (on the right) pronunciation
time for front, middle and back articulation. With this help MSDA
gives a great assistance to determine and document
special articulation problems. Using the client manager all data
and changes of the patient’s speech can be tracked
over time.
MSDA result tracking for 9
records. The trend view shows important motor speech data over time.
You can print out a report form
for recent and over time assessment. Additionally you can do
further acoustic analysis with MSDA
recordings, e.g. spectrography of speech.
