Do you trust smartphones that use always-on sensors to monitor your surroundings for context?

Syntiant Corp announced the integration of its NDP120 Neural Decision Processor into the new STEPX Neo phone. This partnership aims to enhance the capabilities of the LLM-native device through advanced hardware.

Why it matters

The technology allows the phone to conduct always-on audio sensing while maintaining power efficiency and user privacy. By capturing context before a user prompt occurs, the device reduces the need for the main processor to wake frequently.

The STEPX Neo leverages the NDP120 Neural Decision Processor alongside six SiSonic MEMS microphones. This configuration supports continuous, low-power audio sensing to preemptively capture user context.
