Overview

Chat Text uses the Latin script with diacritics to encode most of Earth's natural language features, enough so that you can write every language using the same Latin-oriented system and be close enough to a realistic pronunciation, including nasalized vowels, tense consonants, clicks, and tones, amongst other things. See the index.ts for a list of all the possible symbols and their representation.

In addition to a compact "Latin script with diacritics" version, there is also an ASCII version suitable for writing on a traditional keyboard. This is shown in a faint color in the upper right of each box in the tables below. It is also clearly mapped out in the source code as well.

EaseChat

This is the simplified, diacritic-free version of ChatText, as demonstrated with these example words. Since it is so minimal, it is much easier for an English speaker to read, hence calling it the EaseChat. It's not perfect, but it gets the job done.

| english | ascii | simplified | | :--------- | :----------- | :---------- | | think | ciqk | theenk | | these | Ciz | zheez | | brother | brUCu$ | bruzher | | bend | bEnd | bend | | date | det | daet | | cat | kAt | kaat | | father | faCu$ | fazher | | eventually | UvE^ntxOli | uvenchuulee | | cool | kul | kool | | lately | letli | laetlee | | koala | kOwalU | kuuwaluh | | creature | kritxu$ | kreecher |

The simplified version is meant to be readable if you have some degree of English intuition, but it's not meant to be perfect like it would represent the words in English.

import chat from '@wavebond/chat'

chat.ease('brUCu$') // => 'bruzher'

You can combine this with @wavebond/talk to start from native writing systems, and using that library convert to Chat Text ASCII, then simplify the ASCII into a somewhat readable form!

import talk from '@wavebond/talk'
import chat from '@wavebond/chat'

chat.read(talk.tibetan.read(someTibetan))

FlowChat

This is the more rich formatting of the ASCII characters, using diacritics and trying to keep things relatively minimal while still being reasonably accurate with pronunciation. That is why we call it FlowChat.

| ascii | simplified | | :--------------- | :----------- | | txaando^ | txaandȯ | | surdjyo^ | surdjyȯ | | Ha$!a$@!^rijE | ḥa̱̖ȧ̱̤̖rıjẹ | | H!u&_^th~ | ḥ̖ṵ̄̇tḩ | | eT!e_^mu | eṭ̖ē̇mu | | txya@+a-a++u | txyà̤áȁu | | hwpo$kUimUno$s | hwpo̖kụımụno̖s | | sinho^rEsi | sınhȯrẹsı | | batoo'aH | batoo'aḥ | | batoo'aHh! | batoo'ah̥ | | aiyuQaK | aıyuq̇aḳ |

import chat from '@wavebond/chat'

chat.flow('eT!e_^mu') // => 'eṭ̖ē̇mu'

ReadChat

Here we have included a system inspired by the Double Metaphone algorithm, which is an algorithm which creates a simplified pronunciation "hash" of some input text, usually English or other Indo-European languages.

Since ChatText is itself a simplified ASCII pronunciation system for any of the world's languages (like X-SAMPA or IPA, but easier to write), it was straightforward to make a system where we progressively simplify the pronunciation from accurate to only simplified consonants and no vowels. There are 5 categories of things which get tinkered with when "refining" the pronunciation from its most accurate form, to the most basic form:

• vowel: none, one, basic, all. No vowels, the a vowel, the 5 basic vowels i e a o u, or any possible vowel allowed by ChatText.
• consonant: all, simplified. All possible consonants allowed by ChatText, or a simplified subset, where it basically merges bp, td, xj, fv, sz, and kg, and gets rid of any consonant variants like click consonants or stop/tense consonants (Korean).
• tone: yes, no. Whether or not we include tone markers (useful in Chinese).
• duration: yes, no. Whether or not we include duration markers (useful in Sanskrit).
• aspiration: yes, no. Whether or not we include aspiration markers (useful in Indian languages).

By combining all these characteristics, we end up with something like this (for the word by~oph~am, which has palatalization, aspiration, and a few vowels and non-simplified consonants):

const list = chat.read('by~oph~am')
[
  {
    text: 'by~oph~am',
    mass: 405,
    load: {
      consonant: 'all',
      vowel: 'all',
      tone: 'yes',
      aspiration: 'yes',
      duration: 'yes',
    },
  },
  {
    text: 'by~ph~m',
    mass: 324,
    load: {
      consonant: 'all',
      vowel: 'basic',
      tone: 'yes',
      aspiration: 'yes',
      duration: 'yes',
    },
  },
  {
    text: 'by~opam',
    mass: 270,
    load: {
      consonant: 'all',
      vowel: 'all',
      tone: 'yes',
      aspiration: 'no',
      duration: 'yes',
    },
  },
  {
    text: 'pyopham',
    mass: 270,
    load: {
      consonant: 'simplified',
      vowel: 'all',
      tone: 'yes',
      aspiration: 'yes',
      duration: 'yes',
    },
  },
  {
    text: 'by~pm',
    mass: 216,
    load: {
      consonant: 'all',
      vowel: 'basic',
      tone: 'yes',
      aspiration: 'no',
      duration: 'yes',
    },
  },
  {
    text: 'pyphm',
    mass: 216,
    load: {
      consonant: 'simplified',
      vowel: 'basic',
      tone: 'yes',
      aspiration: 'yes',
      duration: 'yes',
    },
  },
]

The mass is basically a "weight" for now, to say how many features it included, i.e. how close to the actual pronunciation it was. The smaller the mass, the less it is like the original pronunciation.

You then use the text as a key in a lookup table to find words matching that refined text pronunciation. You likely will find the same term in several spots, but you can just filter those at at query time.

That's about it! Now have to play with this in production to see how useful it is in practice for building pseudo-fuzzy dictionary search.

Syllables and Pronunciation

Using the library, you can also count the number of syllables in a word, and convert IPA text into ASCII Call Text.

import chat from '@wavebond/chat'

chat.talk('kxɯʎʎikʰa̠da̠') // => 'kHOly~ly~ikh~a@da@'
chat.mark('kHOly~ly~ikh~a@da@') // => { size: 4 }

Tone Text

You can also transform Chat Text into Tone Text by writing it in ASCII, and running it through the tone text code, which is freely available and open source there.

import tone from '@wavebond/tone'

// make it for the font.
tone.make('a+a+si-kiri-imu-') // => 'a3a3si4kiri4imu4'
