Apple's largest acquisition to date remains the $3 billion purchase of Beats in 2014, but now its second-largest deal involves bringing in Q.ai, a four-year-old AI audio startup. While Apple has not disclosed the specific terms, the Financial Times reports that Apple is investing $2 billion in the company. The report also mentions Q.ai's patents, which involve optical sensor technology that can be built into headphones or glasses to recognize "subtle facial skin movements." This could, for example, enable non-verbal communication with AI assistants.

The founders of Q.ai will join Apple, including CEO Aviad Maizels, who previously founded PrimeSense. Apple acquired that company in 2013 and repurposed its Xbox Kinect technology for the iPhone's FaceID setup. This time, the technology capable of understanding whispered speech could be integrated with a generative AI-upgraded Siri or other Apple smart features, supporting future AirPods, Vision Pro, iPhone, or Mac devices.

Apple's hardware executive, Johnny Srouji, described Q.ai in a statement to Reuters as "an exceptional company pioneering novel approaches to imaging and machine learning." Google Ventures supported this startup. Managing partner Tom Hulme wrote in a blog post that this might help us understand "what happens when computers finally 'disappear' into our daily lives."
