Well there were a number of successor states to Parhae in the tenth and eleventh centuries, which the Khitan continually fought against. And 'Bohai' is still recognised as a distinct ethno-cultural group throughout the Jin and Yuan dynasties, which shows they still had yet to Sinicize or Jurchenize by the fourteenth century. This would indicate to me that they may very well have still spoken a native language. Given that the surnames of Bohai peoples in this period often show descent from Koguryo groups (mainly the Da clan), we could well suppose that they still spoke a form of Koreanic. However, with the rise of the Jurchens in the eleventh century, it's likely that Tungusic became the Manchurian lingua franca in this period. Whether this process began prior to 926 though, I'm not sure. There's some Chinese scholarship that discusses (in part) Parhae language that I'm trying to track down, so I will let you know if I find anything further - although, like most aspects of Parhae history, language is a hotly contested issue still, so there isn't much consensus anyways.
