Seeing at the Speed of Sound

The term "lipreading" implies that the skill is, in a sense, exactly like reading—in which the words on the page are clear and perfectly legible. "Can you read my lips?" strangers ask when they meet me. (Never mind that the question is inherently illogical: If I couldn't lipread, how on earth could I answer?) As they ask it, I can see the other, unspoken questions reeling in their heads—What if she can't? What will I do then? Mime?

When I answer that, yes, I can lipread, they relax. Then they prattle on as if all preconditions are off. Because I can "read" their lips, I must therefore be able to "read" everything they say. After all, it would be absurd for me to protest that I can sometimes read the words in a book, but sometimes not. Either you can read, or you can't. (Likewise, either you can hear perfectly—meaning hear and understand everything—or you can't hear at all. Forget hearing aids and microphones and other assistive devices.)

"How did you learn to lipread?" is another common query. I do not have a satisfactory answer. The truth is, I can't explain it. No more than I could explain how I learned to walk, or than anyone else could explain how she learned to hear and understand language. "Practice," I usually answer. Since I entered a mainstreamed public school in first grade, there have been no other deaf people occupying center stage in my life. My world is primarily a hearing one, and I learned to deal with this reality at a very young age. There was no reason to sign with anyone besides close friends and family, no reason to expect anyone to communicate on my terms. Surrounded by hearing people all the time, my only option has been to adapt, and lipreading is the skill that I have practiced most.

But this answer is too simple. The foundation for my success with communication was laid in my earliest years, at a deaf preschool. That was perhaps the only time in my life when I experienced full communication access each day. Everyone—students, teachers, speech therapists, parents, siblings—signed. From ages 2 to 5, I lived, breathed and conversed with people like me—at least, as alike as a young child understands. There was no reason for me to doubt myself or my abilities, so I grew fluent and confident with language. I learned its nuances, its facial and emotional expressions. I learned that it was not inaccessible, as it would sometimes later seem.

Self-confidence fuels the desire to practice and protects against the degradation of communication breakdown; but my ability to lipread is attributable not only to my own efforts, but also to the contributions of others. When I was less than a year old, my parents started me in speech therapy, which I continued for 18 years. There, I encountered the visual and physical fragments of the sound that was so absent from my world. This sound was mysterious to me. I could not grasp it—even with hearing aids—but I could see it. Under the tutelage of a succession of speech therapists, with support from my family, I became a student of its aftereffects.

In teaching me how to make sound's shapes with my own mouth, they taught me how to focus on their faces with the deepest intensity. Like a detective-in-training, I learned to recognize consonantal stops, the subtle visual differences between a "d" and a "g." (On the other hand, "p" and "b" are all but impossible to distinguish by lipreading alone, because their only difference is that one is voiced and one is not.) I learned how to zone in on the minutest changes in the muscles of the face. Over many years of drills and refinement, I learned how to construct the appearance of functioning like a hearing person. But I did not hear: I saw.
