A systematic and pretty thorough presentation of spoken English. Nuts-n-bolts, yet fairly non-technical:
syllables, stress, stress patterns, pitch change, syllable length, syllable structure, vowel quality, word stress, content words, structure words, rhythm, sentence structure, reductions, contractions, verb auxiliaries, disappearing syllables, consonant clusters, linking - consonant-to-vowel, linking - vowel to vowel, sentence focus, correcting information, checking information, asking for repetition, thought groups, pitch range, pitch curves, voicing, voicing and syllable length, stops and continuants, aspiration(puff of air - p,t,k.) consonant sound contrasts, vowel sound contrasts
listening difficulties, listening accuracy, comprehension, getting key information, taking notes, following structure, keeping track
From the introduction: "It is not necessary to pronounce every sound perfectly to be understood - only a few parts of each sentence are really important, but these parts are essential. The native speaker depends on hearing these parts clearly, therefore you need to know which parts of a sentence must be clear and how to make them clear."
