When we read silently, we often experience the feeling of hearing our voice saying the words our eyes are falling on. Some readers actually move their lips at times during silent reading and there is a considerable amount of muscle activity in the speech tract that can be measured if not experienced as we read silently. What is the function of these activities? In Chapter 3 we argued that access to the lexicon can proceed via either a visual route or a phonological route. Yet most of the time we can clearly hear our voice saying the words in the text and for most readers there is evidence of much speech-like activity in silent reading. In this chapter we will discuss these speechrelated activities in terms of the possible reasons for their occurrence.
