Sound Novels is a trademark of Chunsoft, which used the term for its novel games such as Portopia Renzoku Satsujin Jiken, Otogirisou, Kamaitachi no Yoru, Machi, and more recently 428: Fūsa Sareta Shibuya de (which received a perfect 40/40 score from Famitsu). Sound Novels were the origin of the "novel"-type game genre. Both genres share the style and gameplay. However the term "Visual Novel" is used by non-Chunsoft developers partly to avoid Chunsoft's trademark and partly to emphasize its focus on visuals rather than sound. As later entries in Chunsoft's own Sound Novel series have strengthened its visual expression with 3DCG and real-life graphics, the latter difference have pretty much disappeared.
Despite what the term may imply, not all sound novels have voice acting; the "sound" being merely background music and sound effects. An example of this is the original Higurashi no Naku Koro ni series for the PC, which billed themselves as "sound novels".
