For a fuller account of the phases of speech, see Catford ( 1977),
Chap. 1, and for the vocal tract, ibid., Chap. 2. An illuminating,
but quite different, introduction to phonetics is given in Abercrombie
( 1967), Chap. 1.

Initiation types are gone into in great detail in Catford ( 1977),
Chap. 5. There are also useful descriptions of types of initiation--
under the heading of 'air-stream mechanisms'--in Abercrombie
( 1967), Chap. 2, and in Ladefoged ( 1975), Chap. 6.

Phonation is discussed in Abercrombie, Chap. 1, Ladefoged,
Chap. 6. Various types of voice quality, which we barely touch on
in this book, are gone into in Abercrombie, Chap. 6, and Catford,
Chap. 6, and in very great detail in Laver ( 1980). On aspiration,
see also Abercrombie, Chap. 9.

Articulatory locations and stricture types are dealt with, as 'place
and manner' of articulation, in Abercrombie, Chap. 4, and
Chap. 9 (on stops) and Ladefoged, Chap. 7.

Much the same ground is covered in much more detail in Catford,
Chaps. 10 and 11. On co-articulation see Abercrombie, Chap. 9,
where the sequence types are also discussed, and Ladefoged,
Chap. 9.
