Correction: Mandarin Chinese is considered to have a tonal system, not a pitch-accent system. On one level, you could group together languages with tonal systems and pitch-accent systems together as languages in which the pitch-like qualities of the voice carry phonemic information, but in practice most people treat them as separate categories of languages.
