#2I hope this never takes off.
This whole machine learning, optimization etc, story, but the end goal is that Google can easily transcribe your voice calls and store it as text. Then it can apply all shady practices that it previously was too expensive to do because storing voice and extracting information from it required huge storage costs and actual human labour.
Or worst, just imagine what some government you don't trust could do with all those voice call transcripts.

#3In practical terms, very impressive. Anyone know what latency is like? Feels a domain where people who have not experienced low latency full duplex cannot fully appreciate why voice has faded in everyday life...

This codec has nothing to do with what you're worried about. There's no current technical limitation preventing what you're describing. Google doesn't do it because it makes no sense for their business and because your phone calls aren't routed through Google's servers. Governments outside the US are already doing it.

#6Encoding takes >40ms? Opus takes 5-26.5ms. Apparently 150ms[1] is the generally accepted upper bound for call latency.
I think the article could do with some bandwidth/quality/latency/power comparisons to other codecs.

Can they not do that with opus?

#8Sounds like NVIDIA's Maxine [1], but for voice?

It sounds more like a "offline" codec, not a Google service compressing your voice so I don't immediately see how Google would violate our privacy here this time.
