Complete voice recognition, TFT display driver, Bluetooth audio, and TTS solutions for smart switch, control panel, smart speaker, and connected appliance manufacturers.
Supporting everything from basic voice prompts to offline voice recognition, touchscreen control panels, and Bluetooth music streaming — covering the full range of smart home devices from a single wall switch to a whole-home control hub.
Smart home devices are evolving from single-function switches and sensors into multi-sensory interaction hubs. Hands-free voice control, touchscreen status panels, and Bluetooth-connected speakers are becoming standard expectations for smart switches, thermostats, control panels, and connected appliances.
A smart home device without voice or display feedback increasingly feels incomplete to today’s users — interaction, not just automation, is what buyers now expect.
Wet hands, cooking, or cleaning make touch controls inconvenient. Offline voice recognition lets users control lighting, faucets, exhaust fans, and small appliances without touching a single button.
Wall switches, thermostats, and 86-box control panels increasingly need a screen for status and animation. Waytronic’s display driver SoCs integrate screen drive, audio playback, and capacitive touch on one chip, avoiding a separate touch controller and audio codec.
Many smart home buyers are wary of always-listening cloud assistants. Waytronic voice recognition ICs process everything locally — no audio is ever uploaded, no cloud subscription, no internet dependency, and no added latency.
Kitchens, bathrooms, and living rooms are rarely quiet — TVs, exhaust fans, running water, and appliance noise are common. Waytronic voice ICs use echo cancellation and noise suppression tuned for these real-world home conditions.
Waytronic has been providing voice IC and smart home solutions for over 26 years, helping manufacturers integrate voice interaction, TFT displays, touch control, Bluetooth connectivity, and audio into connected home devices. From entry-level voice prompts to offline voice recognition and intelligent control panels, we offer solutions covering different smart home product tiers.
Cost-Effective Voice Feedback for Smart Switches & Connected Appliances

Bluetooth music/audio streaming from a paired phone or hub、Local voice status and connection prompts alongside streamed audio、App-controlled BLE configuration and firmware updates、Multi-room or multi-device audio setups
Recommended Chips:
WT2605C4-32N
WT2605C8-32N
WT2801A4-32N (BLE-only voice prompt variant)
Key Benefits:
✓ A2DP music streaming plus local MP3 playback on a single chip
✓ BLE 5.4 for independent app control, data sync, and OTA updates
✓ AT command protocol for straightforward MCU integration
✓ External SPI Flash / TF card expansion for larger audio libraries
✓ Voice prompts and streamed music can run independently without interference
For manufacturers building smart switches, thermostat faces, and 86-box central control panels that need a screen alongside voice and touch interaction, the WT2003Bx/WT2606B family reduces BOM complexity while simplifying panel design.
Traditional smart panel designs often require separate:
– Display driver IC
– Touch controller
– Audio codec / amplifier IC
– MCU for coordinating all three
This increases:
BOM cost
PCB complexity
Vendor management complexity
Development time
Recommended Chips by Application Tier:
WT2003Bx — entry tier, small screen (0.96″–2.06″), for basic wall switches and 86-box panels
WT2606Bx — adds BLE 6.0 connectivity for app pairing and OTA panel updates
WT2606BPx — dual-core + 2.5D GPU for smoother animation on thermostat and scene-control panels
Beyond voice and display, Waytronic solutions also support:
Presence & Proximity Sensing: Infrared and microwave radar sensors (WT4001 series, WT41 series) let smart switches and panels detect approach or occupancy, triggering wake-up greetings or automatically adjusting lighting — without requiring a spoken wake word.
Multi-Channel Audio Mixing: WT2003H-series chips support simultaneous playback of background tones and voice prompts, useful for smart home hubs that need to layer chime sounds with spoken status updates.
Expandable Voice & Music Content: Voice packs and background music can be stored on external Flash, TF card, or U-disk, and updated without redesigning the product — supporting firmware-free content refreshes for regional voice packs or seasonal audio themes.
“Turn on the lights,” “Dim to fifty percent” — WTK6900HA delivers reliable 3-5 meter recognition for hands-free lighting control in living rooms and bedrooms, entirely offline.
Wet hands or cooking make touch controls inconvenient. Voice recognition ICs let users control exhaust fans, faucets, and small appliances without touching a switch.
WT2003Bx and WT2606Bx drive small TFT screens on wall switches and 86-box panels, showing icons, scene names, and animated feedback alongside voice confirmation tones.
WT2605-series Bluetooth audio chips let connected speakers stream music from a phone while independently playing local voice prompts for connection status or alerts.
Infrared or radar presence sensors (WT4001 / WT41 series) trigger a voice greeting or automatic lighting change when a user approaches a panel or enters a room, without needing a spoken wake word.
Supports Mandarin, English, and other languages through swappable voice files, letting manufacturers serve multiple international markets from a single hardware platform.
