The device consists of DSP ADAU1701 processor IC manufactured by Analog Devices for audio processing abilities.
The device generats a PWM wave for integrating with sound transducers from PUIaudio. The device would be able to capture the microphone audio, then process the audio data. This processed audio is amplified via an external amplifier.
Project Details: RioSH developed an Hands Free Electrolarynx. HFE is a device which is used to retain the speech who last their Vocal Cords due to vocal cancer. The voice is obtained by an excitation signal which is transmitted through the neck tissue which results in a sound wave inside the oral cavity. By using this device the Patients can speak with his/her vocal cords. Unfortunately product didn’t see sky.
