soundletter

Soundletter is a term used to describe the link between a speech sound (phoneme) and its written representation in a writing system. In this sense, a soundletter is the unitized pairing of a phoneme with a letter or digraph that signals that sound in a given language. The concept is used in phonology, orthography studies, and literacy education to discuss how spoken language is encoded in writing.

In alphabetic systems, a single phoneme may have one or more possible letters. Conversely, a single letter may signal different sounds in different contexts. The study of soundletters often overlaps with discussions of graphemes (the written characters) and grapheme-phoneme correspondences, but the term emphasizes the functional pairing rather than the character inventory alone.

In English, the phoneme /s/ can be written as s, c (before e or i), or ss; the phoneme /f/ can be written as f or ph. In other languages, the same sound may map to different letters or digraphs. Soundletters can also refer to digraphs like th or sh representing single sounds.

Educational use: teachers may present soundletters to illustrate how decoding works in reading instruction. The approach highlights that learning to read involves memorizing reliable soundletter mappings while also learning irregularities.

Limitations: 'soundletter' is not a standard term in all linguistic references. Many scholars prefer terms such as grapheme-phoneme correspondence or phoneme-grapheme mapping. As a result, the concept is often described in more precise terminology in scholarly contexts, while 'soundletter' may appear in pedagogical writings or informal discussions.
