Voice Control for Smart Home
Fully On-Device. Stays Home.
From wake word to action: custom wake word detection, speech-to-text, a local LLM that operates your devices, and text-to-speech responses — all running on-device, with no cloud and no per-token costs.
Why a Fully On-Device Pipeline Matters for Smart Home Products
- ✓Privacy & security — wake word, STT, LLM, and TTS all run locally, so nothing leaves the house
- ✓Speaker verification & voice separation — isolates the owner's voice and rejects commands from other speakers, guests, or a TV/speaker in the background
- ✓Works during internet outages, since the entire pipeline runs without connectivity
- ✓No token dependency — the local LLM means no per-query API costs or cloud inference fees
- ✓No recurring cloud costs per device at scale
- ✓Brand differentiation instead of a generic "Alexa" or "Hey Google" experience
A Complete On-Device Voice Pipeline
Wake Word
Custom branded trigger phrase, always listening on-device with minimal power draw.
→Speech-to-Text
Converts the voice command that follows the wake word into text for the LLM to act on.
→Local LLM
Understands the command and operates your smart home devices directly — no cloud round-trip.
→Text-to-Speech
The LLM talks back, confirming what it understood and what it did.
Built for Teams Building Smart Home Products
App Developers
Building a companion app for lighting, climate, security, or any connected device? Add a full voice pipeline without sending audio to the cloud.
Hardware & IoT Makers
Building a voice-enabled speaker, hub, or appliance? Run wake word, STT, LLM, and TTS directly on embedded hardware.
Platform Builders
Want your own branded "Hey [Product]" instead of relying on Alexa or Google Assistant? Ship a voice experience that's entirely yours.
What You Can Build With DaVoice
Custom Branded Wake Word
Train a wake word unique to your product name or brand, instead of a generic assistant trigger.
Voice Commands via STT
On-device speech-to-text turns spoken commands into text the LLM can use to operate any connected device.
Local LLM for Device Control
A local LLM interprets commands and operates lighting, climate, security, and other devices — no cloud inference, no token fees.
Spoken Responses via TTS
On-device text-to-speech lets the LLM talk back — confirming what it understood and what action it took.
Fully On-Device
Wake word, STT, LLM, and TTS all run locally — works offline and keeps audio and data on the device.
Owner-Only Voice Recognition
Speaker verification and voice separation create a voiceprint for the owner, so only their voice can issue commands — other speakers, guests, or background audio are ignored.
SDKs for Mobile & Embedded
Drop the DaVoice pipeline into your existing iOS, Android, or embedded codebase rather than building voice AI from scratch.
How Integration Works
Add the SDK
Integrate the DaVoice SDK into your mobile app or embedded firmware.
→Configure the Pipeline
Set your custom wake word and connect the LLM to the devices it should operate.
→Ship It
Deploy to your app or device — wake word, STT, LLM, and TTS all run on-device from day one.
See the documentation or integration guides for implementation details.
