sound categories
(e.g. C/V,
obstruents, sonorants, nasals, palatalized consonants, front vowels, nasalized
vowels, etc.) and relations between categories, instead of using sound pairs (the
so-called “suspect pairs”). Sounds that belong to the same (articulatory or
acoustic) category tend to present similar phonological “behaviour”. Cf. The
concepts of
natural class
and
sound feature

Study the distribution of the sounds: i.e. the sum of the different positions in which
they may occur. The principle aim of this study is to examine the
relations
between the
sounds of the language (individual sounds, sounds categories), especially between the
phonetically most similar ones: (paradigmatic)
contrast
,
variation
(free, allophonic),
alternation

computer programme may be extremely helpful.]

Reminder:

(Vertical) contrast
: a sound substitution that changes word meaning.
9
Allophonic variation
: two (or more) phonetically similar sounds that are in
complementary distribution (i.e. that appear in mutually exclusive phonetic
environments).
9
Free variation
: a sound substitution that does not change word meaning.

E.g. Secondary articulations (labialized, palatalized, velarized, glottalized sounds, etc.), affricates, labiovelars, pre- or post-
nasalised consonants, trills, long segments, diphthongs. It should however be noted that sounds that surface as complex units
may derive from underlying sequences.
16
Semivowels and close vowels.

It should however be noted that Silverman (2006:92) advocates strong caution in employing phonetic similarity as a
diagnostic for linguistic relatedness (i.e. linguistic categorization). According to this author, phonetic similarity is not
(necessarily) isomorphic with functional identity.
18
Silverman (2006:87) underlines that all that matters to learners (and speakers) is the consequences the sound substitution
have for word meaning, and that functional identity overrides physical similarity in the determination of category membership
or non-membership. (Phonological symbols represent categories. The question is to what extent these categories match the
ones acquired/used by the speakers.)
