Helping quiet voices be heard
ChatterVOX® began in 1998 as a hands-free amplifier for a revered mentor whose voice had weakened. It still does that job first.
Parkinson’s often quiets the voice. Amplification lifts it gently, so you are heard without pushing.
As speech grows tired, a light amplifier keeps you part of every conversation for longer.
When the vocal cords cannot do it alone, the amplifier carries a breathy voice across the room.
During recovery, or with an electrolarynx, a hands-free amplifier gives a weakened voice volume.
Talking all day strains a healthy voice too. Speak at a relaxed level and let the amplifier work.
Speech-language pathologists have recommended ChatterVOX® for more than 25 years.
ChatterVOX® is a voice amplifier, not a medical device. It does not treat any condition. Follow the advice of your physician or speech-language pathologist about how and when to use it.
Conceived in 1998 for one voice. Used by more than 75,000.
ChatterVOX® was conceived to help a revered mentor of its developer continue enjoying a full life of communication and social interaction. It has since helped people with Parkinson’s disease, ALS, vocal cord paralysis and other conditions, as well as teachers, coaches and guides, be heard without strain.
Every ChatterVOX® is designed and supported by ELT™ Enhanced Listening Technologies in Nashville, Tennessee.
