Voice training became a major problem in voice and speech research disciplines. Medical purposes due to voice disorders, linguistic usage due to public speaking training or educational training are only a few examples where voice analysis and voice training are essential parts. Education, training and analysis of someone’s voice is nowadays supported by assessment sheets, audio or video recordings or even voice measurement and visualization tools. Most of these tools require a suffcient education in linguistics and phonetics and therefore are restricted in their application possibilities. Reliable voice measurement and feedback tools tend to be very expensive because they are not designed for home-usage. This work is based on the vision that voice education can be seamlessly integrated into daily routines.

To come one step closer to this dream, reliable real-time speech analysis will be implemented on an smartphone.
