The Portable Voice Amplifier Model 100 from ChatterVox is a compact wearable speech amplification system, used around the waist, that significantly amplifies the voice and sounds entirely natural.

Who benefits from the Portable Voice Amplifier?

It is originally designed to help people with communication difficulties (as a result of Parkinson’s, Dystonia or other conditions) to be heard even when 'whispering'. It is also suitable for people with permanent or temporary voice injuries or disabilities that affect their speech volume.

One of the most common impairments in advanced Parkinson’s disease (or Dystonia) is hypophonia, a reduction of speech intensity, typically decreasing intelligibility. Hypophonia associated with Parkinson’s especially inhibits communication in noisy environments, on the phone, for a longer period of time, and with unfamiliar listeners or those at a distance.  This may hinder the person’s participation and engagement in communication (as many find it very difficult to make themselves heard) and may even threaten their dignity, value and independence. The Portable Voice Amplifier Model 100 from ChatterVox has been specifically designed and developped for this condition and will help the user gain confidence as she/he can participate again in the conversation.

How does the Portable Voice Amplifier work?

The Portable Voice Amplifier is tailored for indoor and outdoor use. It elevates the vocal output to a level that is effective for everyday communication and improves vocal clarity significantly. It can boost the vocal output by 18dB by using the headset with microphone. As a result, the device provides amplification for 'whisper speech' with a 'mellow' frequency without the emphasis on harsh sounding/ high frequency. The great advantage of the set is the fact that the background noises are minimised enhancing the voice only. This makes the voice clearer and easier to hear. With one simple button, you can quickly customise voice sound enhancement and minimise distracting background noise.
