Voice Analyzer with Super Cross Technology
A speech analysis application for evaluating speech quality. Harmonics to noise ratio (HNR) and harmonics to fundamental ratio (HFR) of speech using a proprietary high-performance zero-cross point detection algorithm is calculated and visualized.
We have released two modes: a mode that continuously plots two indexes related to noise and overtones on a two-dimensional coordinate axis, and a graph display of time-series changes in voice pitch and harmonic energy.
In a quiet environment, the fundamental frequency can also be calculated with high accuracy. Please use it for voice training and singing training.
