King Vajiravudh, however, was not pleased with the system, contending that when different consonants were used in the final position, it was because they represented different sounds, such that a final -ล would, by an "educated" speaker, be pronounced differently from a final -น. He also opposed using a phonetic Thai spelling for "any" word of Sanskrit or Pali origin, arguing that these should be transliterated in their Indic forms, so as to preserve their etymology. While most of Vajiravudh's criticisms focused on the needs and abilities of "learned readers", he argued against the use of "spiritus asper" to indicate aspiration, as it would mean "absolutely nothing to the lay reader".
