Natural voicelifting (named after facelifting ) involves speech therapy, speech exercises focused on voice quality, to achieve a healthy and more pleasant voice.

The exercises are conducted in cycles, based on a method developed by phonetics experts, led by Academician Petar Guberina, at the Institute of Phonetics (now the Department of Phonetics of the Faculty of Philosophy in Zagreb) in the 1950s and 1960s.

The exercise cycle includes an (initial) recording and five half-hour treatments. The exercises (treatments) include speech exercises, pronunciation of words and sentences, and reading of text, completely individualized and tailored to the needs. The experience is dynamic, fun, and educational.

For best results, two cycles are optimal. At the end of the treatment, the voice is acoustically analyzed before and after, and the client receives a visual and numerical representation of the progress.
