diacritictone

Diacritictone is a proposed notation system in which diacritic marks attached to letters encode lexical tone within a writing system. The term blends diacritic and tone and is used in linguistic discussions, experimental orthographies, and some constructed languages to indicate pitch or contour on syllables. Unlike some languages that rely on paragraph-level tone interpretation, diacritictone aims to make tonal information explicit in the written form.

In languages with lexical tone, pitch patterns differentiate meanings. A diacritictone scheme would attach diacritic marks to vowels or syllables to signal high, mid, low, or contour tones. Marking schemes vary by design, with some systems using single marks for level tones and others using combinations or diacritic placement to signal contour movements. The exact mapping is language-specific and can be adapted to different writing scripts.

Illustrative examples (for discussion, not standardized): tá, tà, tả, tã show different marks on the vowel to indicate distinct tones. The precise interpretation of each mark depends on the adopted language model and orthography. In practice, diacritictone concepts are often explored as part of prototype orthographies or learning aids rather than as a universal writing rule.

Advantages of a diacritictone approach include clearer tone representation in writing, potential benefits for language learning, and improved machine processing for text-to-speech and NLP. Challenges include increased typographic complexity, the need for consistent fonts and keyboard layouts, potential confusion with existing diacritics, and the requirement for standardized conventions across languages.

Status and scope: diacritictone is not a widely adopted standard. It appears mainly in theoretical discussions, experimental orthographies, and some conlangs. See also: tone language, diacritic, orthography, linguistic notation.
