> like the homophones b and v

They aren't :) where are you from? do you pronounce "vaso" and "baso" in the same way? (in Argentina and Spain at least they are clearly distinct)

In most of Spain they sound exactly the same. I have met a total of one single person who pronounced them differently. Maybe it depends on the region.

I'm from Málaga, by the way.

I stand corrected! I have visited Catalonia quite a few times and never noticed they being homophones. In Argentina, or at least in Buenos Aires, they even teach you in primary school to pronounce the v using your upper teeth and lower lips (it makes it sound closer to f), and the b only with both lips. I'm very surprised to learn this, can't imagine pronouncing vacaciones as bacaciones hahah that's amazing, I wonder where this difference comes from.
