    Resumé

    This paper presents part of an ongoing research
    program which aims to apply mathematical and
    geometrical analytic methods to vowel formant
    data to enable the quantification of parameters of
    variation of interest to sociophoneticians. We open
    with an overview of recent research working
    towards a set of desiderata for choice of
    normalization algorithm(s) based on replicable
    procedures. We then present the principles of
    centroid-based normalization and account for its
    performance in recent road tests. In sections 4 and
    5 we introduce a method that utilizes the centroid
    of the speaker’s vowel space as an anchor point or
    vertex for calculation of planar locations on
    formant plots, permitting quantification of the
    distribution of vowel tokens within the space. This
    information, along with details such as Euclidean
    distances, can then be used to precisely pinpoint
    the trajectories of diachronic change, for instance
    over a set of speakers in different age groups
    within a defined speech community. This has the
    advantage of mathematical reproducibility, and
    reduces the level of subjectivity in visual analyses
    of formant plots used in investigations of vowel
    variability and change in progress.
