Frequently asked questions

How does voice personalization work?

Picovoice's Eagle Speaker Recognition enables appliances to adapt settings based on who is speaking. Each model runs locally, and voice data remains on-device during use—supporting privacy while enabling tailored interactions.

Will it work while cooking noise is present?

Yes. Picovoice's Cobra voice activity detection and intent recognition models are specifically built to handle noisy environments. Whether it's the sound of a blender, boiling water, or a fan oven running, your commands will still be detected clearly and executed accurately in real time.

Can I use custom wake words and multi-language commands?

Yes. You can define branded wake words and support multilingual commands using Picovoice Console—allowing broader market reach and user flexibility within the same embedded application.

Does it need cloud or Wi‑Fi?

No internet connection is needed for runtime operation—all speech processing occurs on-device. Internet is only required for licensing and usage tracking, ensuring offline reliability without compromising privacy.

What types of appliances are supported?

The SDKs are designed to run across a wide range of devices—from low-power microcontrollers in smart kettles to embedded Linux systems in ovens, coffee machines, and air fryers. Whether you're building for mobile, desktop, web, or IoT, Picovoice offers consistent and scalable voice control.
