The iOS App is largely used in speech therapy, especially with young children (aged 0-3 years) and with autistic people and stroke patients.

Bla Bla Bla is a sound reactive application for iPhone and iPad. This app derives from an exercise called “Parametric Mask”. The exercise was part of a one-day workshop held in December 2010 at the design department of IUAV, in Venice, and in February 2011 at the ISIA of Urbino. The aim of the workshop, called “Procedures of Basic Design”, is to go beyond the classic exercises about shape and perception that characterize the Basic Design course. These new exercises introduce the use of a programming language as a problem-solving tool, but the workshop itself is not focused on programming: the language is a tool, a way to use numbers, math and logic to show objectively how to solve a design problem. The course was aimed to first year students with no coding experience. The language used in workshop activities was Processing. The porting for iOs was written in Open Frameworks.

Bla Bla Bla

This app has helped my students with deafness and other disabilities understand that they can make sounds with their mouths. Students who are mute try to talk with this app.
I am unable to use this app because it says 'waiting' on it. I've tried to delete it so that I could download it again, but it won't delete.
This has been a great tool for my students.
Please help me get it back up.

Great! Wonderful tool!

As a speech pathologist working with the dynamics of voice, this app is excellent at providing dynamic visual feedback! My patients love the way the faces interact directly with their vocal output. Well done!

This app may have started out as an exercise or workshop on programming, but is great to use with special needs kids. It is sound reactive and very sensitive. There are 16 different characters (faces) to choose from, and with each vocalization or sound - the faces get more expressive. You can tailor the sound to each picture, if you wish, and you can use this for cause and effect play, increasing vocalization, or simply visual attention. The graphics are simple drawings - perfect for kids that can't handle too much visual clutter. There are no extraneous IAP, ads or links.
