Routine analysis

Spead: 
A program for voice analysis made by Laryngograph.

MDVP:
A program for voice analysis made by Kay-elemetrics - Pentax.

High Speed Analysis Wolf Ltd.:
This equipment is purchased from Wolf Ltd. which makes us able to record a sample with sound and video of the throat and the vocal cords. 4000 pictures pr. second with fiber optics and stored films (Stoboscopy with only 25 pictures pr. seconds gives a distorted picture), there are 187 measurements in the software, licensed from Erlangen (Prof. Döllinger) for high speed film and analysis, including acoustically analysis, glottal areal waveform, ect.

Phonetography:
Current analysis method includes Lingwaves software (see also thesis/ebook 2014).

Formants and overtones:
Description of intensity maxima of the sound in the human throat. Overtone Analyzer by software company SYGYT(r) used to visualize formants and overtones up to 20.000 Hz, this is valuable for registers and high note problems, in voice recordings.

Medical Voice Hygiene Advice.
Advice on proper use of the voice for optimal function both in singing and speaking, including Voice Handicap Index (VHI) and Reflux Symptom Index (RSI), as well voice related quality of life (VQOL).
