The research that I am conducting represents a logical progression from my PhD thesis(2007). My PhD thesis addressed the issue of lenition/reduction. In the thesis, I found that speakers reduced the duration of vowels in the second and third mention (token) of the same word and concluded that lenition is the default option for a native speaker of English. In addition to speech, I have also investigated reduction in writing(text messaging in Polish and English).
At present, I have extended my research in reduction to the frequency and typology of reduction processes, the role of the rate of speech and reduction in second language acquisition.
