Read moreAnswers to frequently asked questions about our spectrographic speech analysis software for speech therapy and clinical research.
Our algorithms measure quantitative voice parameters such as jitter (frequency instability) and shimmer (amplitude instability). These objective measurements help in mapping vocal cord pathologies for an accurate clinical diagnosis.
The software is primarily developed for speech therapists and researchers in phonetics within academic hospitals. It supports both clinical practice and scientific research into voice disorders.
The software visualizes speech in a frequency spectrum (spectrogram). Waveforms and frequency components are visible within it, enabling a detailed analysis of voice quality, far beyond what the human ear can perceive.
No. We do not develop presentation courses or public speaking training. Our focus is entirely on medical software for objective vocal cord analysis for the benefit of speech therapy and phonetic research.
