Vocal Range Profile

Vocal Range Profile (VRP) is a representation of a clients minimum and maximum intensity levels across his/her vocal range.  Phonetograms are graphical representations of the vocal range profile.  Frequency, as well as intensity ranges are measured yielding quantitative measures.  The following characteristics can be obtained when establishing the vocal range profile:

  Habitual frequency

  Total fundamental frequency range

  Lowest and highest fundamental frequencies

  Habitual intensity

  Total intensity range

  Lowest and highest intensity range

  VRP shapes and contours

(Heylen, L., et. al., 1998)

Vocal range profiles can be used in treatment and assessment.  These areas will be discussed in the clinical application section.
