== Standard/Modern Khmer based on ... == 

  
 Standard Khmer, or Central Khmer, the language as taught in Cambodian schools and used by the media, is based on the Battambang dialect spoken throughout the plains of the northwest and central provinces. 

 The reference does not list what page this is mentioned. The phonology section of the source does not mention Battambang dialect (if you can call it that) being the basis of Standard Khmer. Did I miss it somewhere else in the book?
