OVERVIEW
What is Labex Digitial
Labex Digital is a digital electrolarynx device. It is
specially designed to help laryngectomees talk.
Labex Digital is a CLASS I medical device.
General principle of operation for all models
electrolarynges manufactured by Labex Trade
Ltd.:
The digital electrolarynx produces mechanical
vibrations with a low sound frequency between
60-195 Hz. Applied to the neck, these vibrations
create trembling in the oral cavity compensating
for the energy generated from the lungs.
The combination of starting and stopping sound
vibrations and oral articulation creates
comprehensible speech.

Finding the sweet spot
A sweet spot is called a place on the throat area
where you feel the sound from the electrolarynx
transmits through the neck tissue and out of the
oral cavity with the most clarity.
The easiest way to find your sweet spot is by
tightly pressing the electrolarynx Top Cap in
different locations on your neck area and
articulating a single vowel while pressing the Start
Button.
What you are looking for is the place on your
neck, which best transmits the sound. While
looking for a sweet spot, it is crucial to press the
device tightly against your neck tissue so the
sound transmits through your tissue and out of
your oral cavity. Take your time finding your
sweet spot –this is the most important part of
learning to use an electrolarynx. Finding just the
right place will set you up for success.

First Words
After you have pinpointed the desired spot, you
can start making some basic sounds. It is crucial
to over-articulate every sound with your mouth
until you feel comfortable. After that, you can
start practicing short words. Slowly work your
way up to sentences and conversation.
In some cases, talking can be achieved in a
month, in other cases, it can take only 3 days.
