How the AIA381-M10 Revolutionizes Low-Power Voice Detection

In today’s wearables and smart electronics, energy-efficient voice activation is no longer a luxury — it’s a necessity.

The WBC-AIA381-M10 addresses this need with a hybrid voice detection mode (VAD+KWS). It operates in ultra-low-power voice detection mode (~70µA), and once human voice is confirmed, seamlessly switches to keyword recognition mode (~160µA) for offline wake-up command recognition.

Mode Overview:

• VAD Mode: Continuous listening for voice activity.
• KWS Mode: Keyword recognition from a predefined list of up to 30 phrases.
• Hybrid Mode (VAD+KWS): Smartly toggles between VAD and KWS to balance power and responsiveness.

This capability makes the AIA381-M10 the perfect AI front-end for voice-first systems in consumer electronics, reducing reliance on cloud processing while increasing privacy and speed.
