# System for Uniform Phonetic Representation (SUPR)
By: Simon Y. Blackwell, Copyright 2024


# Executive Summary
The System for Uniform Phonetic Representation (SUPR) is a flexible, keyboard-friendly transcription system designed
for both non-tonal and tonal languages. It uses standard keyboard characters and provides consistent modifier stacking
to support both left-to-right and right-to-left writing systems. The system offers basic coverage for non-tonal
languages and enhanced notation for tonal languages, making it suitable for digital input and monospace fonts while
maintaining explicit and unambiguous notation. It is also designed to express phonetics using either Latin characters
or in the readers native script and adds mood modifiers (exclamation/question) to phonetic mapping. The focus is on 
automated text conversion as well as cross-language standard keyboard input, readability, and utility for indexing 
dimensions that may impact semantics beyond syllables rather than precise acoustic representation.

# 1. Introduction
## 1.1 Purpose
The Uniform Phonetic Writing System provides a standardized method for phonetic transcription that balances accuracy,
ease of input, and universal compatibility. It was designed as a simpler alternative to the International Phonetic Alphabet
in order to support phonetic indexing across languages, but may also serve researchers, linguists, and language
learners who need a practical system for digital phonetic notation in either a Latin character set or their native language.

We hope you find it useful.

# 2. Base System
## 2.1 Base Characters
Consonants
Labial: p b b' m f v w
Dental/Alveolar: t d d' n s z l r
Postalveolar: [sh] [zh] [ch] j
Palatal: c [gj] [nj] y
Velar: k g [ng]
Uvular: q (Voiceless uvular stop) G (Voiced uvular stop) [qh]
Glottal: h ['] (for glottal stop)
Implosive: [b'] (Voiced bilabial implosive) [d'] (Voiced alveolar implosive)

Vowels
High: i u [ue] [uh] (Unrounded high back vowel)
Mid: e o [oe] [eh] (Open-mid front unrounded vowel)
Low: a [aa] [ao]


## 2.2 Structural Markers
Grouping
Simple cluster: [kw]
Optional element: (t)
Complex cluster: str
Vowel combinations: [oe], [ue], [ae]

Boundaries
Syllable: . (middle dot)
Morpheme: -
Word: space
Phrase: > (LTR), < (RTL)
Sentence: >> (LTR), << (RTL)

Sentence with mood: 
- >>? >>! (LTR questions/exclamations)
- ?<< !<< (RTL questions/exclamations)

Boundary Guidelines
Boundary markers are context-dependent indicators of text direction and structure
Use minimal markers to convey necessary directional or structural information
Phrase markers (>, <) are recommended for:
- Disambiguating text direction in mixed-language contexts
- Clarifying text structure in complex transcriptions

Sentence markers (>>, <<) are used for:
- Longer passages or complete sentences
- Indicating distinct paragraph or section boundaries

Omit markers for:
- Single words or short phonetic fragments
- Contexts where text direction is already clear
  The primary goal is clarity without unnecessary notation.

## 2.3 Writing Direction
Left-to-Right (LTR)
- Basic Version: base + feature + length + stress
- Enhanced Version: base + feature + length + stress + tone
- Boundaries: > (phrase), >> (sentence)
- Sentence Mood: Append ? or ! after >> for questions/exclamations

Right-to-Left (RTL)
- Basic Version: stress + length + feature + base
- Enhanced Version: tone + stress + length + feature + base
- Boundaries: < (phrase), << (sentence)
- Sentence Mood: Prepend ? or ! before << for questions/exclamations


## 2.4 Metadata Markers
Metadata markers use a curly brace containers {key:value,...} where multiple key and value pairs are unquoted identifiers or strings without spaces. The marker appears immediately before sentence (>>), phrase (>), or word delimiters. Multiple metadata markers may be present.

### 2.4.1 Language Codes
Language codes are specified using the metadata marker format {lang:ISO-code} to indicate the source language of subsequent SUPR text. This supports automated translation and reversibility.
Guidelines for Language Code Markers:

- Place immediately before sentence (>>), phrase (>), or word delimiters
- Process left-to-right, applying to all subsequent text until another code appears
- Use standard ISO language codes (e.g., {lang:eng}, {lang:ara}, {lang:heb})
- Optional but useful for mixed-language contexts or where there is a desire to support teaching for written language expression
- Some SUPR encodings may reverse to different written characters depending on the specified language code

# 7. Reader-Native Expression

The System for Uniform Phonetic Representation (SUPR) supports expressing phonetic transcriptions in a reader's native script while maintaining the system's structural integrity. The eliminates the requirements for readers to full understand non-native characters. This capability relies on the metadata markers, boundary indicators, and consistent phonetic mappings defined in previous sections and appendices.

## 7.1 Script Transformation Rules

When expressing SUPR in a reader's native script, the following elements must be preserved:

Structural Markers:
- Syllable boundaries (.)
- Morpheme boundaries (-)
- Directional markers (>, <)
- Sentence markers (>>, <<)
- Metadata containers {key:value}

Language Context:
- Language specifiers {lang:code} must be maintained
- Language-specific mappings from Section C must be applied
- Script direction conventions must follow Section 2.3

## 7.2 Transformation Examples

Airport Sign in Multiple Scripts:

Original SUPR:
{lang:eng} > b[ae]cg[i][dj] kl[ei]m > {lang:ara} [i]s.ti.l[aa]m < [a]l.[a]m.ti.[a] << {lang:heb} ka.ba.l[a]t < me.t[a].[a]n > {lang:eng} t[er].mi.n[a]l > [th]ri:

Arabic:
{lang:الإنجليزية} > بَاجِد كليم > {lang:العربية} إِستيلام < المَتيا << {lang:עברית} كابالات < ميتان > {lang:الإنجليزية} ترمينال > ثري

Hebrew:
{lang:אנגלית} > בַאגִד קלים > {lang:العربية} אִסתילאם < אלמתיא << {lang:עברית} כאבאלאת < מיתאן > {lang:אנגלית} טרמינאל > תרי

# 8. Reader-Native Pronunciation Guides

## 8.1 Core Principles

Reader-native pronunciation guides transform SUPR notation into familiar sound patterns using the reader's native language conventions. The goal is to make pronunciation immediately accessible without requiring knowledge of phonetic notation or unfamiliar scripts.

### 8.1.1 Transformation Rules

1. Sound Mapping
  - Map SUPR phonemes to closest native language equivalents
  - Preserve syllable structure and stress patterns
  - Use native conventions for indicating length and stress
  - Convert tone markers to native tone notation where relevant

2. Structure Simplification
  - Replace SUPR boundary markers with natural punctuation
  - Remove metadata markers
  - Use standard writing conventions of target language
  - Break complex syllables at natural points

3. Visual Format
  - Original text
  - Native script pronunciation guide in parentheses
  - Optional meaning in square brackets when helpful


### 8.1.2 Cross-Script Examples

English "Supermarket" for Different Readers:

Arabic Script:
supermarket (سوبَر-ماركِت)

Korean Script:
supermarket (슈퍼-마켓)

Japanese Script:
supermarket (スーパー・マーケット)

Chinese Script:
supermarket (苏泼马克特) [超市]

## 8.3 Complex Examples

### 8.3.1 Multi-Language Airport Sign

For Arabic readers:
Original: "Baggage Claim استلام الأمتعة קבלת מטען Terminal 3"
Guide: باجِج كلَيم - إستِلام الأمتِعة - كابالات مِطاعَن - تيرمينال 3

For Korean readers:
Original: "Baggage Claim استلام الأمتعة קבלת מטען Terminal 3"
Guide: 배기지 클레임 - 이스틸람 알암티아 - 카발라트 메타안 - 터미널 3

### 8.3.2 Tonal Language Examples

Mandarin "你好" for Japanese readers:
你好 (ニーハオ↓↑) [こんにちは]

Vietnamese "xin chào" for Korean readers:
xin chào (신˯ 짜오˘) [안녕하세요]

# 9. Semantic Nuance and Phonetics

Since the initial impetus for SUPR was to provide a system for phonetic indexing across languages for information retrieval, it is important to consider the impact of phonetic distinctions on meaning. This section explores how SUPR can capture tone-based, stress-based, length-based, and phonation-based semantic nuances in various languages.

## 9.1 Tone-Based Semantic Distinctions

### 9.1.1 Mandarin Chinese
- Single syllable semantic differentiation through tones
  - mā (妈, "mother") vs má (麻, "hemp") vs mǎ (马, "horse") vs mà (骂, "scold")
- SUPR representation: m[a]^ vs m[a]^- vs m[a]_^ vs m[a]^_
- Compound meaning shifts through tone sandhi
  - 买马 (mǎi mǎ) → m[ai]_^ m[a]^ (tone change affects meaning preservation)

### 9.1.2 Vietnamese
- Six-tone system encoding both meaning and grammar
- Tone as grammatical marker in compounds
- Example: có (to have) vs cỏ (grass)
  - SUPR: k[o]^- vs k[o]_^
- Complex tone interactions in compounds preserving semantic distinctions

## 9.2 Stress-Based Meaning

### 9.2.1 Russian
- Stress position changes lexical meaning
- Example: замок (castle) vs замок (lock)
  - SUPR: z[a]'.m[o]k vs z[a].m[o]'k
- Stress shifts in declension preserving core meanings

### 9.2.2 English
- Noun-verb pairs distinguished by stress
- Example: "permit" (n) vs "permit" (v)
  - SUPR: p[er]'.m[i]t vs p[er].m[i]'t
- Compound stress patterns indicating relationship type
  - "greenhouse" vs "green house"
  - SUPR: gri:n'.h[au]s vs gri:n > h[au]s'

## 9.3 Length and Gemination

### 9.3.1 Japanese
- Phonemic length affecting meaning
- Example: obasan (aunt) vs obaasan (grandmother)
  - SUPR: [o].ba.s[a]n vs [o].ba:.s[a]n
- Gemination distinctions
  - kite (come) vs kitte (stamp)
  - SUPR: ki.te vs ki.t:e

### 9.3.2 Arabic
- Root meaning preservation through consonant length
- Example: kataba (wrote) vs kattaba (caused to write)
  - SUPR: ka.ta.ba vs ka.t:a.ba
- Vowel length semantic distinctions
  - kitāb (book) vs kutub (books)
  - SUPR: ki.t[aa]b vs ku.tub

## 9.4 Glottalization and Phonation

### 9.4.1 Vietnamese
- Glottalization affecting both meaning and register
- Final glottalization as semantic marker
  - Example: học (study) vs họp (meet)
  - SUPR: h[o]k vs h[o]'p

### 9.4.2 Burmese
- Phonation types encoding meaning
- Creaky voice as semantic differentiator
  - Example: တီ /ti/ (umbrella) vs တည် /tḭ/ (stable)
  - SUPR: ti vs ti'

## Appendix B: Digital Implementation And Usage Guidelines

- create index entry
  1) convert original text to compressed SUPR format
  2) create an index entry as a JSON object with keys 'full' and 'syllableOnly' with empty objects as values 
  3) lower case
  4) tokenize ignoring punctuation
  5) convert each token to compressed SUPR form 
  6) add to full and syllable only index it does not exist 
  7) increment count for each syllable in full and syllable index 
  8) return index object
  
- query in any language:
  1) determine primary language of query
  /*2) translate query language to all target languages (will require call to LLM)
  3) convert each translation to its SUPR compressed form*/
  4) find matching ids based on the full compressed SUPR form and syllable compressed SUPR form
  5) score each id based on the number of matches
