Linguolabial fricatives

Spencer trying out various labial fricatives and trills
For those non-phoneticians, bilabial means “with both lips”, and linguolabial means “with tongue and lips”. The difference between trills and fricatives can be subtle. Trills usually involve a repeated flapping. A common trill is the [r] in the Spanish word perro “dog”, as opposed to pero “but”. The latter is just a single flap. In contrast, fricatives tend to have constant friction. Sometimes some of these sounds are commonly referred to as “raspberries”, or “blowing a raspberry”. I personally have always thought blowing a raspberry necessitated one making these sounds on someone else, in particular the tummy. Does anyone else agree with me on that one, or am I all alone?
Spencer seems to be enjoying trying out all of these variations.
