worldbet: Convert WorldBet to IPA

This micropackage converts WorldBet ASCII characters for English sounds into UTF-8 character and HTML entities.

Inside of R: RStudio

RStudio has rich support for UTF-8 symbols. Here is how some WorldBet-to-IPA conversions look in RStudio.

library("worldbet")

# that
convert_bet_to_ipa("D@t")
#> [1] "ðæt"

# uh-oh
convert_bet_to_ipa("^?o")
#> [1] "ʌʔo"

# water, weather (vector input)
convert_bet_to_ipa(c("wA)&_r", "wED&_r"))
#> [1] "wɑɾɚ" "wɛðɚ"

Inside of R: Command Line

From the command prompt on Windows, R falls back to escape sequences during the conversions.

# that
convert_bet_to_ipa("D@t")
#> [1] "ðæt"

# uh-oh
convert_bet_to_ipa("^?o")
#> [1] "<U+028C><U+0294>o"

# water, weather (vector input)
convert_bet_to_ipa(c("wA)&_r", "wED&_r"))
#> [1] "w<U+0251><U+027E><U+025A>" "w<U+025B>ð<U+025A>"

Outside of R: HTML Entities

For RMarkdown documents, we can use HTML entities for in-text use of IPA. For example, we could write the following RMarkdown in our prose:

The word was /`r convert_bet_to_entity('SIp')`/ ("ship").

RMarkdown-to-markdown conversion then yields the following text with HTML entities instead of WorldBet symbols:

The word was /ʃɪp/ ("ship").

Finally, markdown-to-HTML conversion yields the following human-readable form of the symbols.

The word was /ʃɪp/ ("ship").
