Is it time to don an Expert hat here?
In the course of my post-doc research in computer speech recognition (as well as in voice training as a singer), I learned a lot about how you articulate different sounds (it's pretty fundamental to teaching a computer that we have a clear picture of the problem it's to solve). There is indeed a difference between an articulated P and a W, though it's quite subtle. There's a bigger difference between "Pe" and "Wo", as the mouth opens for the brighter vowel.
But if we could
rely on that, computer speech recognition would've been a solved problem back when I was working on it in the early '90s. The fact is, it's much harder because people don't in practice articulate so clearly. Those syllables are
not clearly distinct in real-life speech, let alone in subconsciously-muttered non-speech.
Lip-reading for the deaf works because the reader has a lot more context to help disambiguate, and because the speaker is making the effort to speak clearly. And because the listener is prepared to ignore an utterly unimportant ambiguity. Lip-reading for espionage uses a great deal more effort to get the gist of something, but is still less than reliable.
What is always easy to see is what confirms a strongly-held prejudice.
As for Corbyn, could he have got away with just calling out the Thought Police, and saying "
my unspoken thoughts are my business, not yours"? That could've provoked a much more interesting debate, and shone a light on totalitarians in both parties.
p.s. The stupid woman of this thread title is still the one who described it as a man "shouting down" a woman.
