This is extremely cool!!! Also I find surprising that, as a Spanish speaker with no whistle-spanish training, I was able to understand most of the whistles.
Interesting! Spanish isn’t a tonal language, so how do you ‘translate’ the words into whistles? (And do you think you could do it without subtitles?) (I should note I haven’t actually managed to watch the video yet, because my audio seems to be broken. Perhaps it would be obvious if only I could hear the whistles…)
Does it happen to you that when you think of a word in English, even if you don't vocalize, some of your vocal cords become tense or move? Well, these whistles feel the same.
