Abstract: An attenuator is disclosed that enables a microphone's relatively undistorted pick up of a voice that is generated in close proximity to the microphone. This attenuator is a key component of a groundbreaking assistive device or handset/headset that empowers individuals with speech impairments to effectively communicate and reintegrate into society. By leveraging advanced acoustic hardware, intelligent voice algorithms, and a comprehensive image-or-vocabulary-to-impaired-voice database, the handset/headset facilitates understanding the user's impaired speech by harvesting understood terminology and outputting the same in a communicative context. Thus, the handset/headset enables seamless public interaction, independence, and improved quality of life to the user with speech impediments and ensures equal participation and inclusion in everyday verbal interactions.

Abstract: The acoustic attenuator also serves as a protective microphone enclosure that reduces exposure to debris as well as environmental humidity 5 and harmful gases.

Abstract: Disclosed is a precisely controlled microphone acoustic attenuator that lowers the sound pressure level to minimize microphone distortion. The acoustic attenuator also serves as a protective microphone enclosure that reduces exposure to debris as well as environmental humidity and harmful gases.
