Vocal Assessment
Vocal Assessment provides you with the ability to analyze and display both acoustic and EGG features of a sustained vowel.
System Overview
Vocal Assessment provides you with the ability to analyze and display both acoustic and EGG features of a sustained vowel. A wide range of parameters (jitter, shimmer, NNE, etc.) and graphic displays (spectrogram, F0, intensity, etc.) are offered. Used to guide diagnostic assessments for voice disorders by measuring hoarse, harsh, and breathy voice.
Features
- Provides diagnosis and rehabilitation data about laryngeal function signals (voice signals, laryngeal acoustics signals) and speech signals.
- Uses precise signal detection and processing.
- Easily edit and store your collected data.
Recommended for

- ESL teaching
- Public Schools
Functions
— Advanced multidimensional voice parameter detection and analysis.
— Provides a comprehensive report for voice quality assessment using acoustic parameters – jitter, shimmer, fundamental frequency tremor, amplitude tremor, normalized noise energy (NNE), harmonic-to-noise ratio (HNR), signal-to-noise ratio (SNR).
— Useful for patients with moderate hoarseness, mild roughness, and severe breathiness.
— When used in combination with EGG, provides data such as: contact quotient (CQ), contact index (CI), open quotient (OQ), closed quotient (CQ), contact quotient perturbation (CQP), contact index perturbation (CIP), etc.
— Provides analysis of glottal closure time and vocal cord vibration regularity.
— Comprehensive comparison of mucous wave irregularity to make up for the lack of laryngoscopy.
