I doubt the guts of something like an Echo would be capable of containing any kind of speech to text model. It'll probably be a lot more of a concern in a few years when speech models like that are getting baked into cheap chips for consumer devices, though.
I'm not as doubtful: iPhones have had on-device speech recognition since at least 2019, with iOS 13[1]. Amazon might have legal or policy reasons for not doing offline speech recognition, but the technology has been there for a while.
