็Homophone are words that have exactly the same sound (Pronunciation) but different meanings and (usually) spelling.
In speech perception homophones are semantically ambiguous, whereas in speech production no ambiguity occurs: when a homophone is heard or read it can only be disambiguation by the listener with the help of context, whereas when generating homophones the relationship between concept and word form is clear-cut to the speaker.
Homophones where one spelling is of a threatening nature and one is not have been used in studies of anxiety as a test of cognitive models that those with high anxiety tend to interpret ambiguous information in a threatening manner.
The term “homophone” may also apply to units longer or shorter than words, such phrase, letter or groups of letters that are pronounced the same as another phrase, letter or group of letters.
