宋高僧傳 20.44

20.44

系曰：些之聲為商為羽耶？通曰：「傳家采錄，其例有二：一則按文不音，二則口授知韻。今得些者，按文也。若楚詞聲餘，則蘇箇切也，若山東言少，則寫邪切焉。此師荊楚間事也，其二音以聽來教，『些』名同鳥獸之自呼也。」

The appraisal says: Is the sound of 'xie' the shang tone or the yu tone? The explanation says: In the compiler's gathering of records, there are two precedents: first, following the written text without indicating the pronunciation; second, receiving it orally and knowing the rhyme. Now that we have 'xie', it follows the written text. If it is the trailing sound of the Songs of Chu, it has the fanqie pronunciation su-ge; if it is the Shandong term for 'few', it has the fanqie pronunciation xie-xie. Since this master's affairs took place in Jingchu, either of the two pronunciations may be accepted as instruction; the name 'Xie' is like birds and beasts calling their own names.
