# According to the pinyin definitions I've been able to find:
# 'a', 'e' are the preferred bases
# otherwise 'o'
# otherwise last vowel
# The trailing form of syllables are the following:
#         "a", "ai", "ao", "an", "ang",
#         "o", "ou", "ong",
#         "e", "ei", "er", "en", "eng",
#         "i", "ia", "iao", "ie", "iu", "ian", "in", "iang", "ing", "iong",
#         "u", "ua", "uo", "uai", "ui", "uan", "un", "uang", "ueng",
#         "ü", "üe", "üan", "ün"
# so the letters the tone will 'hop' are:
::NFD (NFC);
$tone = [\u0304\u0301\u030C\u0300\u0306] ;
# Move the tone to the end of a syllable, and convert to number
e {($tone) r} → r &Pinyin-NumericPinyin($1);
($tone) ( [i o n u {o n} {n g}]) → $2 &Pinyin-NumericPinyin($1);
($tone) → &Pinyin-NumericPinyin($1);
# The following backs up until it finds the right vowel, then deposits the tone
$vowel = [aAeEiIoOuU {u\u0308} {U\u0308} vV];
$consonant = [[a-z A-Z] - [$vowel]];
$digit = [1-5];
$1 &NumericPinyin-Pinyin($3) $2 ← ([aAeE]) ($vowel* $consonant*) ($digit);
$1 &NumericPinyin-Pinyin($3) $2 ← ([oO]) ([$vowel-[aeAE]]* $consonant*) ($digit);
$1 &NumericPinyin-Pinyin($3) $2 ← ($vowel) ($consonant*) ($digit);
