Mm. Good point. I wonder if that's why Microsoft has notices that their AI "requires Edge" - I'd assumed they were just trying to get people to switch browsers and a UA spoof did seem to work fine, but I hadn't tried any TTS features. Having platform behaviour be a defacto part of the spec is probably not a downside for them :) It's definitely funny that this article portrays this as Firefox removing functionality.
