- Apple announced on Thursday that it has acquired QAI, an Israeli artificial intelligence startup specializing in voice technology.

QAI’s founding team will join Apple, including the CEO who previously founded PrimeSense, a 3D sensing company, and sold it to Apple in 2013. The PrimeSense deal later helped Apple move away from fingerprint sensors in iPhones and toward facial recognition technology.

Apple did not disclose the terms of the deal or the purpose of using QAI technology, but said the startup has been working on new machine learning applications to help devices understand speech in low-volume environments and improve sound quality in challenging environments.

Apple is adding new artificial intelligence features to AirPods and last year introduced technology that allows it to translate speech between languages.
