Ironically, Siri (as a virtual assistant) came from SRI's Darpa program "CALO" back in the 2000's. SRI also has a speech recognition platform called EduSpeak, and that is the codebase that was licensed to Nuance for their product.
However, after Siri was sold to Apple, I don't think that they retained the EduSpeak portion for speech-to-text. (I honestly don't know - but it seems to me it did not; I don't think Apple wanted to pay that license fee to SRI).
