Voice Measurement and Analysis

Speech Studio is Laryngograph's voice analysis system provides a Laryngograph and acoustic waveform. It gives precise analysis of sustained vowels and uniquely, connected speech.

 Features:

• Laryngograph Processor provides a Laryngograph (EGG) and Speech input.
• 4 channel CD quality recording and playback.
• USB 2.0 interface allows use with desktop or laptop PC.
• Narrowband or broadband spectrogram.
• Continuous display of closed quotient (Qx) and fundamental frequency (Fx)
• Jitter, Shimmer and HNR measurements for continuous vowels.
• Extensive library of quantitative analysis for connected speech. These work on different kinds of speech pattern including fundamental frequency, speech amplitude, vocal fold contact quotient, nasality and function.
• Optional Nasality Processor for temporal nasalance measures.
• Advanced methods of voice analysis are linked to diagnosis and stroboscopy.

The Laryngograph Processor

A portable electro-laryngograph, microphone pre-amplifier, and speech or Laryngograph based fundamental frequency (”pitch” ) extractor.

• It examins vocal fold contact during voice production via electrical conductance, without interfering with the processes of speaking or singing.
• It determines voice pitch, regularity, loudness and quality.
• In addition to use for normal voice detection, the equipment can also be used with oesophageal speakers and for work in dysphagia.
• The optional nasality processor provides an integrated basis for interactive training and temporal nasalance measurement.
