Audible recognition study

In 2007 Julian McGlashan and Cathrine Sadolin conducted a study ‘Is it possible for professionals with very little training in CVT to hear the modes?’ ‘Assessing the validity of a method for classification of all singing voice into four vocal modes as taught by ‘The Complete Vocal Technique’.

The conclusion was that with relatively little training it is possible to recognise the four vocal modes as with a high degree of agreement (inter and intra-rater reliabiliy).

The result indicates the percentage of correct answers for recognition of Overdrive:

Result from 1st test: 86,5%
Result from 2nd test: 96,5% (after 14 days of practising with CD)

This study was presented by Nazia Munir presented at PEVOC7  in Groningen, Holland in 2007.

 

Visual & waveform recognition test result on stills of Overdrive

In 2008-10 Julian McGlashan and Cathrine Sadolin conducted a study ‘Laryngeal gestures and Laryngograph data associated with the four vocal modes as described in the Complete Vocal Technique method of singing teaching’.

The conclusion was that there appears to be recognisable laryngeal gestures associated with production of each of the four vocal modes. The visualising of the synchronously obtained Laryngograph waveforms provides additional supportive information to the visual images for correct mode identification.

The result indicates the procentage of correct answers for recognizion of Overdrive:

Laryngeal gestures in Overdrive on stills : 78,9%
Laryngograph waveforms in Overdrive on stills: 48,5 %
Laryngeal gestures and waveforms on stills: 84,6 %

This study was presented by Cathrine Sadolin and Julian McGlashan at BVA ‘Choice for voice’ conference in London, England, 2010.

 

Visual & waveform recognition test result on video of Overdrive

In June 2011 Julian McGlashan and Cathrine Sadolin conducted an additional study  ‘Laryngeal gestures and Laryngograph data associated with the four vocal modes as described in the Complete Vocal Technique method of singing teaching.’  This time the participants looked at video recordings of the first 4 bars  of “Somewhere over the Rainbow” instead of stills.

Again the conclusion was that there appear to be recognisable laryngeal gestures associated with production of each of the four vocal modes. The visualising of the synchronously obtained Laryngograph waveforms provide additional supportive information to the visual images for correct mode identification.

The result indicates the procentage of correct answers for recognition of Overdrive:

Laryngeal gestures and Laryngograph waveforms in Overdrive on video : 57,3 %
