In the week of February 1, 2026, Samsung was granted six related US patents in the Voice AI domain. The patent numbers: US12536993, US12536992, US12536999, US12537000, US12537002, and US12537005. They cover the entire stack — from wake-word detection to multimodal device control.
The Core Patent: Self-Calibrating Wake-Word Detection (US12536993)
The most technically significant patent is US12536993 (False Wake-Up Suppression). Claim 1 describes a two-stage ML pipeline:
- Stage 1: A first model evaluates the wake-word probability from raw audio
- Stage 2: When a threshold is exceeded, a second model evaluates based on ASR text output, audio features, and device context data
- Self-calibration: The threshold of the second stage is dynamically adjusted — based on the measured accuracy of the first model
The patent is broadly worded: It covers any two-stage wake-word verification system that uses ASR output as a second pass and adjusts its thresholds based on first-model accuracy. Most production voice assistants already use device context, which does little to limit the scope of protection.
AR/XR-Relevant: Vision + Voice (US12536999)
US12536999 describes a wearable device that combines camera imagery and voice input to identify and control target devices. The direct use case: AR/XR glasses that recognize smart home devices and control them via voice commands.
This patent is immediately relevant for Meta (Ray-Ban Smart Glasses), Google, and Apple's XR programs. The combination of camera-based device identification and voice control is becoming standard in AR glasses — and Samsung has now secured it through patent law.
Patent Family and Reach
US12536993 was filed in June 2023 (priority October 2022) and has a PCT application (PCT/KR2023/008934) with designations in Europe and China. Samsung is pursuing worldwide protection. The cluster appears coordinated, not as a continuation series — the patents cover complementary aspects of the same Voice AI platform.
Competitive Landscape
The cluster directly competes with:
- Apple's Siri wake-word and device control stack
- Google's Assistant on-device ML pipeline
- Amazon's Alexa false-wake suppression systems (Amazon has its own patents for multi-stage wake-word verification)
Manufacturers of smart speakers, TVs, or wearables that use two-stage wake-word verification with ASR feedback should review US12536993 for potential exposure. Samsung has historically favored cross-licensing over litigation, but this cluster significantly strengthens their negotiating position.
