Well yes of course, I just meant that them having voice transcription AI even in the 60s is not that unlikely, since they did a lot specifically in speech synthesis and audio analysis, besides everything else. I don't think they had it, but they had some of the important prerequisites figured out.
I guess it makes sense, voice-related AI is highly relevant for a phone company.
EDIT: Not full voice transcription, but it turns out that they did have systems to recognise digits and small (~a dozen) vocabularies of command words.
The prototype called Audrey could recognise 0-9 spoken digits with 97% accuracy in 1952! Although it did have to be calibrated for each individual speaker.
