Vocoder Testing

Project Overview: The Science and Technology Directorate Command, Control and Interoperability Division (CID) is partnering with the International Association of Fire Chiefs, federal agencies, industry leaders, and firefighters nationwide to improve digital radio transmissions in high-noise fire response operations by testing the digital Vocoder. This working group identified the Vocoder-a hardware/software component in every digital radio-as the cause of voice distortion in radios. When affected, the Vocoder may endanger the lives of responders and those awaiting help. CID will help train responders on how to minimize the distortion and will partner with radio manufacturers in the development of smarter radios. This project is part of the Office for Interoperability and Compatibility within CID.
