A voice enhancement device including an earpiece configured to be positioned in an ear canal of a user. A microcontroller is operatively coupled to the earpiece. The microcontroller is configured to selectively provide at least multitalker babble. An accelerometer is located within the earpiece and operatively coupled to the microcontroller. The accelerometer is configured to detect speech by the user and communicate with the microcontroller to provide the multitalker babble to the earpiece during the detected speech by the user. A method of making the voice enhancement device, and a method for increasing vocal loudness in a patient using the voice enhancement device are also disclosed.

Devices that train voice patterns and methods thereof

One example embodiment of the present disclosure includes method and system to improve communication comprising an assembly fixedly positioned during use in close proximity to a user's ear. The assembly includes an accelerometer to detect the initiation and duration of the user's speech and an output presentation system. The output presentation system comprises a non-occlusive ear fitting that presents unintelligible noise that is unrelated to the sound-frequency or intonation of the user's current speech. The unintelligible noise is presented to the patient at a level less than 85 dB. The system further comprises a control arrangement to maintain presentation of the noise substantially throughout the detected duration of the user's speech, but substantially not at other times.
