Our future work aims to reduce the size and cost of the device by replacing parts such as the Arduino nano unit with microprocessor chips.
Initial hardware testing to establish control response time and operating time for users prior to subject testing
Two part testing system uses a survey to evaluate convenience rating and a second randomly selected audibility test to evaluate the listener end experience.
There are over 100,000 tracheostomies a year, of which these individuals must use an electrolarynx which performs poorly. Our Team believes that we can address this shortcoming through wireless controls and ample sound insulation.
