The model of “tomato” in Figure allows for a coarticulation on the first vowel by giving two possible phones. An alternative approach is to use a tri-phone model in which the [ow (t, m)] phone automatically includes the change in vowel sound. Draw a complete tri-phone model for “tomato,” including the dialect variation.
