“…2 Actors must be able to adjust their vocal production to their performance space, whether it is a 100-seat theater or a 3000-seat auditorium, while maintaining the intonation range necessary for expressing a wide range of emotions. 3 The projection skills of actors with experience performing Shakespearean plays are of particular interest. For these actors who rely on their voices rather than amplification, optimal projection is crucial.…”

“…Interestingly, Acker (1987) found that actors have greater articulatory excursions associated with a resonant voice than a constricted voice. Radiographic measures revealed that resonant phonation greatly increased oral cavity size (by 36 mm) and jaw lowering (by 14.6 mm) when compared to constricted phonation.…”

“…Acker (1987) compared samples of resonant phonation and constricted phonation, and claimed that resonant voice is both perceptually and acoustically louder. The study used one subject who was a female actor trained in the Lessac technique.…”

“…The different physiological states employed by the subject between the different modes of singing assessed by Acker (1987) Although use of these techniques would be hard to encourage directly at a physiological level, it may be that a form of graphical visualization based on acoustic analysis, operating in real-time, could incite the appropriate physiological actions that are required for this phenomenon.…”

“…Although the vocal sound utilising the singer's formant appeared to be louder than the constricted form of vocal articulation, the recorded SPL was only slightly higher. This implies that the effect of the singer's formant gave the impression that the vocal sound was more predominant.This would clearly be an important quality to encourage in singing training.The different physiological states employed by the subject between the different modes of singing assessed by Acker (1987) Although use of these techniques would be hard to encourage directly at a physiological level, it may be that a form of graphical visualization based on acoustic analysis, operating in real-time, could incite the appropriate physiological actions that are required for this phenomenon. …”

The human voice is used regularly in day-to-day activity, particularly by teachers, politicians and singers. This can place a level of strain on their vocal mechanism. To counter this, professional voice users may undergo some form of vocal tuition. However, there is a prevalence of subjective, sometimes ambiguous tuition techniques.Vocal damage can therefore occur in spite of, or partially because of, the tuition techniques that are supposed to help the subject.It is hypothesised that a computer system which can a) objectively measure a large set of parameters relating to vocal performance, b) appropriately translate these parameters to a smaller set of easily interpreted measures, and c) dynamically display this information in an appropriate graphical form may be able to provide a measure of progress to complement instructive techniques during vocal tuition.A highly flexible, easy-to-use tool for the analysis and visualization of voice source and acoustic signals has been developed called ALBERT (Acoustic and Laryngeal Biofeedback Enhancement in Real-Time). The system can be used to provide real-time feedback on the state of a number of voice parameters. The visualization of these parameters is highly configurable, and includes 1D, 2D and 3D arrangements with optional colour mapping. ALBERT is novel in its ability to display many popular laryngeal and acoustic parameters in many informative graphical configurations. The system can be used in real-time to function as a tool for use by a voice tutor.To test the hypothesis, three studies are presented of vocally developing male and female subjects as follows: i) a six week course of vocal expression, ii) a group of actors over an eight month period, and iii) a group of singers over a time span of 2.7 years. Two voice parameters in particular have been identified as indicative of vocal performance: the closed quotient of the vocal folds (CQ) and the spectral amplitude in the frequency band within which the phenomenon of the 'singer's formant' is known to occur relative to the spectral amplitude of the complete acoustic output (Ratio). ALBERT has been used as a tool to provide real-time visual feedback of these parameters in the context of singing tuition. Results suggest that ALBERT is a tool with considerable potential for use in a voice tuition process. 2.4 General arrangement of the vocal organs (From Crystal, 1987) .. 11 2.5 Physiology of the human head (From Sataloff, 1992 2.10 Vocal tract profiles for two vowels.
