When did you last feel your ears ‘pop’ and lose the sound of your own voice?
Like many people, this happens to me fairly frequently on flights and car journeys. Adapting to the muffled world of partial hearing is quite intriguing as it offers a rare glimpse into what my brain is doing behind the scenes while I’m having a simple conversation. Of course, I’m always extremely grateful when my hearing returns to normal again.
Our awareness of speech is organised for the most part around our perception of sound, which is probably why our awareness of the rapidly changing jaw movements or the movements of facial muscle groups is suppressed while we are speaking. Consequently, losing the sound of our own voice is extremely disruptive to normal speech production.
If like me you’ve tried to persevere with a conversation in the absence of sound perception, you may have experienced that the movement sensations produced by facial muscles and jaw muscles are no longer suppressed, but that you become aware that your perception of your facial muscles is magnified, revealing in detail the intricate facial shapes necessary for the formation of syllables and words.
Even though the power of speech feels far slower and more effortful in the absence of sound, it’s still possible to continue speaking by monitoring the rhythmic patterning of the jaw and the facial muscles. In this way, rhythm unifies intention and movement in language, overriding the temporary disruption to the auditory system.
Losing the sound of my own voice made me realise how tiring communication can become if the sounds of language are not clearly relayed from the voice to the auditory system. It also indicated the importance of the role of rhythm as a bidirectional frame both for anticipating and tracking the number of syllables produced in an utterance.
The development of early reading depends on the efficient coordination between the ear and the eye. Strong associations between letters and their sounds help children to learn to recognise words on the page. Voices matter too. Educators have realised that poor oral language skills are a strong predictor of poor literacy (Stackhouse & Well, 1997) and that socially disadvantaged children are more likely to lag behind in their vocabulary development when compared with more affluent peers (Fernauld et al, 2013). However, research indicates that sharpening rhythmic awareness supports children’s ability to process information (Long, 2016), better perceive the sounds of language, to read more fluently and with more understanding (Long, 2014).
