Hi Rafaela, 

you probably know that in Germany we use a lot of "Mundbilder" 

I defined a set of symbols to represent these lip and tongue movements that
go along with what you can see if a person is speaking (even without sound) 

I just wrote your two signs

1) it is a short "Brumm"  a long "U" could be interpreted differently but in
general I do not distinguish between long and short vorcals if it is not for
the purpose of articulation.

2) Papa - is easy to understand. 

Have a great day 

Stefan

Betreff: Mouth symbols

Hello everyone. Hope everthing is well.

I have 2 doubts/questions and I hope someone can help me!

1 - SW have a facial symbol for the expression "bruumm" that we do with the 
mouth, for example, when we want to imitate or explain the sound of a 
motorcycle?

2 - SW have a symbol that represents the mouth opening and closing 
consecutively? (As babies do whe they are starting to talk, like
"papapapapa")

Thank you.

Rafaela
