High-fidelity simultaneous speech-to-speech translation

If Finnish is not widely known, German is more familiar, and there you can put the "nicht" at the very end of a sentence, reversing its meaning. Also, the verb may come close to the end, after an extended description of the subject / object; in English, you want the verb early.

Human translators somehow handle that; machines would likely exhibit a similar delay.

Vaguely related anecdote: have you ever dictated a number to a French speaker? When you say “forty-two” or “seventy-six”, an English speaker will start writing the 4 or the 7 the moment they hear the “forty” or the “seventy”. The French speaker will also write the 4 the moment they hear the “quarante” in “quarante-deux” (40+2), but when you say “soixante-seize” (60+16), they will (without thinking about it!) only start writing 76 at the end of the whole thing, because after only hearing the “soixante” they can’t tell if they’ll need to write a 6 or a 7.

Belgian have figured this correctly

I've never heard of an english speaker doing that.. .. .. NOT!
