Summary
AIStorm and DB HiTek have launched SpectroMic™ KWS, a fully integrated keyword-spotting solution that packs a MEMS microphone, programmable amplifier, charge pump, adaptive voice-activity detector (VAD), and charge-domain spectral engine into a 5.5 × 5.5 mm package, drawing only 18 µA in always-listening mode. Models and software support a variety of microcontrollers—including Raspberry Pi Pico-class devices—allowing developers to wake the host MCU only on relevant audio events, and use compressed spectral buffering to cut rolling-buffer memory by 8× and power by 10×.
Why it matters
Coverage in Semi IP Hub—a go-to news source for semiconductor-IP and embedded-systems professionals—spotlights AIStorm’s leadership in ultra-low-power, charge-domain AI solutions. For hardware engineers and systems integrators, SpectroMic™ KWS delivers plug-and-play, always-on keyword spotting with minimal power overhead. Strategic partners see clear evidence of our platform’s scalability across consumer and industrial IoT voice-interaction applications.
