The problem is, that the locations of accents (I.e. the position of prominent syllables) isnít associated with any particular local shape of F0.These are data from the IViE corpus (Grabe and company, Oxford, circa 2002).†† They are local fits of polynomials to prominent (red) syllables and non-prominent places (randomly chosen between the prominent syllables).†† As can be seen, the prominent and non-prominent syllables have essentially the same F0, slope, and curvature.†† Thus, a Tilt-model analysis of speech will not be able to find prominent syllables by looking for bumps.
