Based on
definition: Phomemes are contrastive.
When you have two or more
sounds, found in identical 
environments, (transcribed identically except for
one sound) that 
mean different things.
Example: 
[bij] ‘bee’   [phij] ‘pea’/‘pee’
The sounds [b]
and [ph] contrast in minimal pairs
and thus belong 
to separate phonemes.
[suw] ‘sue’ 
  [zuw]  ‘zoo’
The sounds [s]
and [z] contrast in minimal pairs and thus belong to separate phonemes.

General Enviornments
 & Notations:
1. Word boundaries  
¡word
initial   #_____ 
¡word
final    ______#
2. Before certain sounds;
before sound classes
¡___i, ____s, ____ N, ___ palatals, ___C, ___V
3. After certain sounds;
after sound classes
¡i ___, s ____, N ____, palatals
___, C___, V___
4. Between certain
sounds; sound classes
¡i____i, s____s, N___N, pal.___pal., C__C, V__V
Data Pattern #2 – 
Complementary Distribution, cont.
Example: Spanish
[dexo]    ‘finger’
[donde]  ‘where’  
[naxa]  ‘nothing’
[pixe]   ‘3p
sing. asks’
[pwexe]  ‘3p
sing. can’  
[pared]
  ‘wall’
[r]= flap (symbol won’t show)
Also, [d] = dental
Note that
phones are phonetically similar
¡Both
dental (dental vs. interdental)
¡Both
voiced
[d] occurs in:  elsewhere
  #___e
  #___o
  n___e
  e___#
[x] e___o  V___V
  a___a
  i___e
  e__e
The phones [d] and [x]  are found in 
complementary distribution and
thus belong to
 the same phoneme. [d] and [x] are
allophones of the same phoneme /d/.
/d/
[x]  V_V

Data Pattern #3 – 
Analogous Environments
Based on
definition: Phomemes are contrastive.
This pattern is when you find two
sounds in 
nearly the same environments, but do not have 
data for a minimal
pair.  The appearance of these 
two sounds
does not seem to be conditioned by 
any specific phonetic environments, because 
they both occur in analogous environments.
Data Pattern #3 – 
Analagous Environments, cont.
Analagous Environments, cont.
lExample:
#___a  #____a
i___a  i_____a
  i_____a
These phones are found in analogous 
environments and thus
belong 
to different phonemes. These sounds are 
allophones of different 
phonemes.
Data Pattern #4 – 
Free Variation
Free Variation
Based on
definition: Phomemes are realized by allophones
This pattern is when you find two
sounds in the same environments, and there does not seem to be a change in
meaning. In other
words, it appears that the phones can interchange with one another with no
effect in meaning.  This is usually a result of phonetic
distinction that you perceive that is not contrastive in this language.
Data Pattern #4 – 
Free Variation, cont.
Free Variation, cont.
Example: English
Both
of these phones are found in identical 
environments, and yet, unlike the
analogous 
environments examples, alternation of these 
phones does NOT create
differences in meaning.
Thus, both the [p] and the [p] (unreleased) 
are allophones
of, and thus belong to, the 
same phoneme.
To summarize…
To show you have
allophones of the same phoneme:
1.Complementary
Distribution 
¡phones occur in unique, separate, 
individual
environments
¡environment of sounds conditions 
allophone
2.Free Variation
¡Phones occur in the exact same 
environments or near-identical 
environments but don’t change 
meaning
¡Seem to be used interchangeably, or 
substitute for one another,
are realized as allophones.
Phonemes
To show you have
allophones of different phonemes:
1.Minimal Pairs –
¡sounds occur in exactly the same 
environments
– in an IDENTICAL set 
- AND changes meaning of words
¡
2.Analogous Environments 
¡Phones occur in overlapping 
environments, and in near-identical 
environments, but word meanings are
 different
