Vocal Assessment provides you with the ability to analyze and display acoustic and EGG features of a sustained vowel. A wide range of parameters (jitter, shimmer, NNE, etc.) and graphic displays (spectrogram, F0, intensity, etc.) can be obtained as well.
When the user has a video capture card and camera, images can be captured and stored with the user information. The monitoring of clinical results can be viewed by selecting past sessions for comparison in multiple displays. Comparison can be made with a normative data base of 2973 normal voice and 902 pathological voices to determine if the current recording falls within normal limit on each of the acoustic parameters. Based on that comparison, preliminary voice quality estimates are made of hoarseness, harshness and breathiness.
