The only metadata profile that we have is one that is used to tailor your actual interactions with Siri. For example, we are training our voice models to do natural language recognition on the sound profile. This is really just within the Siri business or the Siri experience. If your question is whether it informs some broader profile used by the company to market products and services, the answer is no.
