Different systems called 'Signed English' have been developed in Australia, New Zealand, Ireland, the UK, the US, Kenya, and South Africa. However each 'Signed English' has borrowed signs from the local deaf sign language and invented new signs to represent the words and grammar of English. They tend to follow a loose logic of sound rather than the strict phonetic structure of Cued Speech. For example, in Australian Signed English 'uncomfortable' is represented in signs meaning 'un', 'come', 'for', and 'table'. A visual sign taken from a deaf sign language may be generalised to represent homonyms of the English word – for example, the Auslan sign for a 'fly' (insect) may be used in Signed English for the verb (to) 'fly'.
