The orthographical depth of a language impacts on a learner's ability to learn a language (Katz & Frost, 1992). If it is easier for learners to read the language as it is written, it will make the learning process easier. One way to address the problem of orthographically deep or opaque languages where the pronunciation is not very easy to determine is to demystify its pronunciation by using animation. This involves showing learners graphically how a combination of certain letters or diacritics produces a particular sound. This is particularly useful when the combination is different to what might be expected given the learner's knowledge of how those letters or symbols sound individually. This is also important when two orthography systems may appear similar on a superficial level but are actually different. This paper provides an overview of the animation component of the CALLIPSO system--a CALL resource for Irish orthography and pronunciation. Irish uses the same letters as the English alphabet but there are differences in the letter-sound correspondences. In the animation component, words are passed to the animation tool which demonstrates how each combination of letters gives rise to the overall pronunciation of the word. The tool is language independent and can be used for languages other than Irish. [For the complete volume of short papers, see ED572005.]
