    • 2004, Stephan Gramley, Michael Pätzold, A Survey of Modern English, Routledge (→ISBN), page 80:
      All vowels, whether short or complex, are relatively shorter when followed by a fortis consonant and relatively longer when followed by a lenis one or, for those where this is possible, when no consonant follows (in free or unchecked syllables).
