Figure 4. Potential phonemic ambiguity in the acoustic-phonetic realization of vowel stimuli.

Figure 4

Each point on the vowel space chart represents the position of a vowel stimulus spoken by each talker in F1×F2 space. The distance between vowel categories is greatest in the easy phonetic contrast condition and smallest in the hard one. Note that the orientation of the axes is consistent with the articulatory position of the vowels.
