Kosmo turned to the trusty Teensy 3.2 and Audio Adaptor to craft a replacement for the out-of-production Kenwood VS-2 Voice Synthesizer, commonly used in HAM radio.

The VS-2 is a voice module for the Kenwood TS-850, TS-690, TS-450 and other transceivers, which announces frequency and other settings upon request, making it of particular utility to blind operators. WAV files can be loaded from SD for complete customization.
