Figure 6. Examples of tongue shapes developed in the sounding of vowels and consonants. These images are 3D reconstructions from ultrasound slices (see text). The upper left-hand image is a consonant, the upper right a ‘front vowel’. The lower left image shows the shape for another front vowel, and the lower right a ‘back vowel’. The reconstructions are reproduced with permission from Dr. Maureen Stone and were originally published in Stone and Lundberg (1996).
