Voice input does not recognize en passant as legal move

Exact URL of where the bug happened

Example of an e.p. capture in a puzzle: https://lichess.org/training/nvucg

The voice input doesn't recognize en passant captures. The voice input gets the correct transcription of "c takes b six", but it doesn't do the move even though it's possible with my mouse.

Steps to reproduce the bug

1. Turn on "Input moves with your voice" setting at "https://lichess.org/account/preferences/game-behavior"
2. Go to the linked puzzle for example of e.p. move
3. Use voice input to say "C takes b6"

What did you expect to happen?

I expected the en passant move to work.

ie, for the c pawn to move to b6, capturing the b5 pawn.

What happened instead?

Nothing

There is no 'en passant' in the vocabulary ... I think you just say 'b6' in this case (the destination)

You're right that it's just "b6". I just tried that and couldn't figure that out.

But it's strange that "C takes B6" doesn't work, but works in other positions.

You are right, this is not consistent with algebraic notation ...

Consider following position ... with the voice input, you have to use the disambiguation mecanism ...

There may be a possible improvement here

Yeah, this looks like it could be improved.

When solving puzzles I usually just say "takes", although recently puzzles with less obvious solutions have been added.
