Voice Is Becoming a Key Feature in Smart Locks

Smart locks are evolving from simple access devices into intelligent home interfaces. Voice interaction, personalized greetings, AI recognition, and remote communication are becoming important differentiators for premium smart lock products.

Voice is no longer a premium feature — it’s becoming the new standard for smart locks.

Why Add Voice Capability to Smart Locks?

Voice technology enhances smart lock reliability, improves user interaction, and enables faster product innovation.

Reliable Access Experience

Fingerprint recognition can fail due to wet fingers, dry skin, or poor lighting conditions. Voice interaction provides users with an alternative and reliable way to control smart locks.

Enhanced User Experience

Clear voice prompts guide users through unlocking, setup, password management, and system notifications, reducing operation confusion.

Smart Voice Without Battery Concerns

Low-power voice processing technology enables intelligent features while maintaining long standby time for battery-powered smart locks.

Personalized & Global Applications

Support customized wake words, greetings, and multilingual voice prompts to meet regional requirements and different product positioning.

Smart Lock Backplate Integrated Solution

Smart Lock Backplate Integrated Solution

Replace Multiple Components with One Intelligent Control Chip

For manufacturers seeking a low power voice chip for battery-powered smart locks with integrated motor control, the WTV series backplate solution reduces BOM complexity while extending battery life.

Traditional smart lock designs often require separate:

  • MCU
  • Voice IC
  • Wireless module
  • Motor driver
  • Battery management circuit

This increases:

× BOM cost
× PCB complexity
× Power consumption
× Development time

Frequently Asked Questions

Waytronic supports five update methods: on‑board programming via SPI/UART, MCU‑driven rewriting over SPI/UART/IIC, PC USB virtual drive, USB stick insertion, and Bluetooth/Wi‑Fi OTA. This gives you flexibility for debugging, production, and remote multi‑language updates without hardware changes.
Yes. All chips support standard UART, SPI, and IIC interfaces, so they integrate easily with most MCUs. You can add them as a voice module, or use the WTV series as a single‑chip backplate replacement that combines MCU, voice, and motor driver functions, reducing BOM and PCB complexity.
The WTV backplate series offers deep sleep as low as 2 μA, while the WTN and WT588 series stay below 5 μA. Even AI‑enabled WT2606 chips have shutdown currents under 5 μA. This enables over 12 months of battery life under typical daily use.
Yes. Built‑in Flash models hold up to 890 seconds for one language, and external SPI Flash expands to 128 MB for Mandarin, Cantonese, English, Korean, Japanese, and more. You can also customize wake words, greetings, TTS, and user‑recorded messages via app.
Yes. The WT2606A chip offers offline recognition with 99 % wake‑up accuracy within 3 meters, built‑in noise reduction, and over 200 local commands – response under 100 ms. For hybrid needs, the WT3000A module adds online TTS and cloud AI when internet is available, but core functions stay offline.
