Voce Vista and Voiceprint are two powerful programs for analysing the voice with aid of a computer. These programs visualize the voice on a computer screen in a power spectrum, showing how the energy of the sound is distributed among the subsequent harmonics (see for an illustration the website of Voce Vista. Where are the strongest frequencies visible in the voiceprint? This information can tell us about how efficient the voice works. Although everyone has a unique voice, we all share most of the characteristics while having the same options. From a spectrogram we can collect information on: intonation, legato phonation, clarity of tone, singer's formant, presence of noise, and further on. There is a Voiceprint version available that includes sung expert samples of every single EVT exercise.
If you do not want to run a voice analysis all by yourself, simply ask for assistance. I am willing to help you getting started!
Voiceprint aids the practicing of EVT-figures
At the Estill World Voice Symposium V in Rome in 2011, Hanny and Marja Reinders presented a study on the application of Voiceprint (VP) in training singing students. VP stimulated the students to practice more frequently and they learned their skills faster. A publication on this topic is in preparation. A Dutch summary can be viewed by clicking this link.
