I published this a while ago as part of tone script (https://github.com/drumworkteam/...). Basically, you write in ascii the pronunciation of words, and the call script JavaScript library will transform it into the Call Romanization Scheme. If you are into languages, you'll know that basically every language and/or writing system has its own latin/romanization scheme, so there are dozens if not hundreds of variations in the usage of the Latin alphabet. This makes it hard for non language experts to read words in other languages, you have to know what letter means what in that context. With call script, every sound is mapped to a unique symbol with or without diacritics. It's all mapped out in the repo. This way you can ideally write in one way across languages using the Latin alphabet, including tones, clicks, and other things the English language doesn't have, in a simple and clean syntax. Note, the English "r" as in "world" is written here as "ṳ" because it is more of a vowel if you really think about it. The Spanish "r" is what r is reserved for. English is unusual in this case.
