What’s the rationale for the way Rosetta Stone breaks down words in the Pronunciation Activity?
We tailor the content in the pronunciation activities specifically toward helping students improve their pronunciation. We design these activities to teach a student to pronounce a word well by providing listening and pronunciation practice on each word segment in order.
For this reason, we break down words into segments that make sense phonetically rather than morphologically. (We focus on word morphology in the grammar activities.)
For example, although the verb 'to wash' is conjugated by adding 'ing', we don't want to train students to say 'wash ing', but rather 'wa shing'.
The breakdown we use matches the pronunciation breakdown you would find in a standard dictionary.
