Lisp

Background
A lisp (O E wlisp, stammering)[1] is a speech impediment, historically also known as sigmatism.[2] Stereotypically, people with a lisp are unable to pronounce sibilants (like the sound [[Voiceless alveolar fricative|Template:IPA]]), and replace them with interdentals (like the sound [[Voiceless dental fricative|Template:IPA]]), though there are actually several kinds of lisp. The result is that the speech is unclear.
- “Interdental” lisping is produced when the tip of the tongue protrudes between the front teeth and “dentalised” lisping is produced when the tip of the tongue just touches the front teeth.
- The “lateral” lisp, where the Template:IPA and Template:IPA sounds are produced with air escaping over the sides of the tongue, is also called ‘slushy ess’ or a ‘slushy lisp’ due to the wet, spitty sound. The symbols for these lateralized sounds are in the Extended International Phonetic Alphabet for speech disorders, Template:IPA and Template:IPA.
- Finally there is the “palatal lisp” where the speaker attempts to make the sounds with the tongue in contact with the palate.[2]
