PHONETIC_ENCODING_JAPANESE_YOMIGANA

For reading-to-pron conversion to work well, the pronunciation field should only contain Kanji, Hiragana, and Katakana.

The pronunciation can also contain pitch accents. The start of a pitch phrase is specified with ^ and the down-pitch position is specified with !, for example:

phrase:端  pronunciation:^はし
phrase:箸  pronunciation:^は!し
phrase:橋  pronunciation:^はし!

We currently only support the Tokyo dialect, which allows at most one down-pitch per phrase (i.e. at most one ! between ^).
PHONETIC_ENCODING_PINYIN

Used to specify pronunciations for Mandarin words. See https://en.wikipedia.org/wiki/Pinyin.

For example: 朝阳, the pronunciation is "chao2 yang2". The number represents the tone, and there is a space between syllables. Neutral tones are represented by 5, for example 孩子 "hai2 zi5".
