While speaking today at the All Things D conference, Nuance CEO Paul Ricci confirmed that Nuance does indeed help power the voice recognition service for Siri.
Since Siri’s launch in 2011, many people assumed that Apple had formed a partnership with Nuance, but neither company has officially confirmed the relationship.
During the his interview, Ricci was asked whether it’s his company’s fault if the iPhone doesn’t understand a user’s voice. Ricci confirmed that Nuance does power the voice part of Siri, but the company is not involved in speech-recognition efforts with Google.
