trill

If you're fluent in Spanish, you are probably able to speak with a trill, or a fluttering r sound.

Many languages include a trill in their pronunciation, the sound of a consonant spoken while the tongue vibrates in a very specific way against the teeth or roof of the mouth. To pronounce this sound is also to trill. The word originally referred to a vibrating or warbling sound made by a singer, from the Italian word trillio, "a quavering or warbling," and it's also often used to describe the sound a bird makes.
