Here's the problem: All these companies, no matter whether the do something that is objectively Ok or not, have to but what they do into non-threatening words so that the population stays calm. Whether they are up to no good or not doesn't make a difference. But by doing so, they don't give people the information they need.
"Anonymized" can mean so many things. When you post here as AppleScruff1, I have no idea who you are, where you live, what you look like and so on. So we could say you are anonymous. On the other hand, there are hundreds of posts under the same name, and I assume they are by the same person. So I can look at your posts in the context of other posts, and you are not anonymous. However, if you post on some other site under a different name (say if you are a member of the South Californian Rabbit Breeders, or a member of the Italian Olympic Rowing team, and frequently post on their websites) I wouldn't know, so that again is anonymous.
If what Apple stores is a voice clip with no information associated with it, so if there is no way to know that clip 1 and clip 2 come from the same person, that would be fine with me. From what I hear about Google, they do connect pieces about the same person. If they know ten thousand pieces of information that all belong to the same person, you, and the only thing they don't have is your name and address, that's not anonymous in a practical sense.
