The email I received has untranslated words. Why?
Most likely those words were not recognized by the translation software. Word misspellings, including missing word accents in Spanish words, are a common source of unknown words. The current version of the TradĂșceloAhora! email translation system performs accent mark restoration on Spanish texts. It will be extended to limited automatic spelling correction on English and Spanish texts. However, it is better to spell-check emails before sending them.
