Product Description: 

Dr. Voice: Voice Assessment is a speech analysis program that provides professionals and home users with the ability to analyze and display both acoustic and EGG features of a sustained vowel. It is used to guide diagnostic assessments for voice disorders by measuring hoarse, harsh, and breathy voice.

Main Features: 

  • It offers a range of parameters (jitter, shimmer, NNE, etc.) and graphic displays (spectrogram, F0, intensity, etc.).
  • Designed to improve speech, hearing, language, cognition, vocabulary, reading, and functional skills.
  • Provides diagnosis and rehabilitation data about laryngeal function signals (voice signals, laryngeal acoustics signals) and speech signals.
  • Uses precise signal detection and processing.
  • Users can edit and store their collected data.
  • Provides a 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), and contact index perturbation (CIP).
  • Provides analysis of glottal closure time and vocal cord vibration regularity.
  • Comparison of mucous wave irregularity to make up for the lack of laryngoscopy.

Primary Specifications: 

  • Windows 7 SP1 and above.
  • Hard drive with at least 1GB of free space.
