Smart Prompter: WT4101 Radar Sensing + WT2605C Voice Chip with Online TTS Technology – Redefining Contextual Interaction
In 2025, smart prompters are evolving from simple voice-playback devices into contextualized intelligent interaction terminals. As traditional infrared sensing hits its limitations, how can enterprises break through? Guangzhou Waytronic decodes the technological revolution in smart prompters!
I. Core Architecture: Radar Sensing + Online TTS Synthesis
What defines a truly smart prompter?
Simply put, it should integrate long-range sensing, real-time multilingual synthesis, ultra-low power operation, and contextual intelligence. It’s like installing a “smart core” for any space – capable of perceiving, understanding, responding, and delivering personalized services across scenarios.
Today, Waytronic explores how radar sensing and online TTS technology are revolutionizing spatial interaction:
WT2605C Voice Chip: The engine of this revolution. It supports online TTS synthesis in 30+ languages/dialects, adds background effects, and generates personalized prompts from real-time data. Critically, its integrated Wi-Fi/4G protocols enable OTA updates as simple as refreshing a webpage.
WT4101-C01 Microwave Radar Module: The system’s “long-range eyes.” Unlike IR sensors (1–3m range), it achieves 0–13m adjustable detection at just 38μA operating current. Translation: A standard lithium battery powers devices for months, solving traditional solutions’ power drain.
Synergy: When fused, these technologies spark transformative chemistry. Devices proactively sense environmental shifts (time, context, user profiles) to deliver precise voice services.
Flexibility: Via Waytronic Home App, one device switches roles/IP personas. A morning office assistant becomes a lunchtime restaurant guide, then an evening security component – slashing deployment costs while boosting operational efficiency.

II. Applied Scenarios
Smart Office: Context-Aware Assistant
8:50 AM, weekday rush: Employees arrive unsure about a 9:00 AM strategy meeting. The wall-mounted prompter detects timing/occupancy via radar and clock, triggering a warm broadcast:
*”Good morning team! It’s 8:50. Today’s all-hands meeting starts at 9:00 in Conference Room C. Wishing you a productive day!”*
Cost Efficiency vs. Manual Alerts:
↗️ 85% faster information delivery
↘️ 60% fewer repetitive communications
⚡ Near-zero maintenance (6-month battery life)
Smart Retail: Hyper-Personalized Engagement
Fixed greetings feel archaic. Our TTS-powered prompter auto-detects and welcomes shoppers in their language:
“Welcome! Today’s promotions are on the third floor. Enjoy your visit!”
Competitive Edge:
30+ language support → Localized experiences → ↗️ Customer satisfaction/repeat visits
Smart Security: Active Deterrence
Legacy systems miss threats. WT4101’s 13m radar range + multilingual warnings create proactive protection:
“Restricted area. Leave immediately. You are on camera.”
Key Features:
13m long-range sensing
Real-time multilingual warnings

III. End-to-End Ecosystem
Hardware: *WT2605C + WT4101*
WT2605C: 32-bit processor with online TTS + Wi-Fi/4G. Stream audio from Waytronic Cloud or mobile app.
WT4101: 38μA power draw (vs. IR’s 200mA) → 99.98% lower consumption.
Software: Waytronic Home App
Manage TTS synthesis, recordings, and OTA updates. Bluetooth support simplifies close-range (<10m) setups.

3.Cloud: Waytronic Cloud Platform
Offers TTS APIs, device/usage management, and private deployment. Batch updates + usage-based pricing democratize enterprise-grade intelligence.

IV. Innovation Value: Reshaping the Industry
Intelligence Leap: From “static alerts” to “dynamic interaction” via radar positioning + real-time TTS.
Cost Optimization: Ultra-low power → zero wiring; cloud updates → zero onsite labor.
Market Differentiation: 30+ languages + 13m sensing + extreme efficiency = premium B2B value.
V. Future Trends: 4 Key Shifts
AI Integration: Predictive capabilities + contextual awareness → devices evolve into proactive assistants.
Multimodal Interaction: Fuse voice, vision, and gestures → natural, intuitive engagement.
Edge Computing: On-device processing → faster response + enhanced privacy.
Ecosystem Synergy: Interconnect with lighting, security, and environmental systems → unified smart spaces.
Guangzhou Waytronic pioneers radar-voice fusion, steering smart prompters from function-driven to experience-led solutions. In an interconnected world, every space deserves smarter, more thoughtful interactions.
