We give choice to voice

You can operate your voice completely locally or pass speech processing to our cloud, which focuses on privacy.

• Concentrated local processing - Limited to a fixed list of commonly used phrases that control the home, this even allows low-power hardware systems to process speech locally and offline.
• Full local processing - Full speech processing is done locally, which requires high processing power to ensure proper speed and accuracy.
• Home Assistant in the Cloud - Your voice is processed privately in the Home Assistant Cloud, which allows Assist to work very accurately on low-power equipment.

Assist is supposed to support more languages than other voice assistants, but it’s still a work in progress and we need your help.

Polish

• Local processing - Running this language locally is not supported.
• Home assistant in the cloud - This language supports cloud computing, which allows for fast and accurate processing even on low-power Home Assistant systems.

English Language

• Local processing - Both concentrated and full local processing are supported in this language.
• Home assistant in the cloud - This language supports cloud computing, which allows for fast and accurate processing even on low-power Home Assistant systems.
