“…A high boundary tone on the phrase-final syllable distinguishes questions from statements in Swedish (Hadding-Koch & Studdert-Kennedy 1964), Venda (Ziervogel, Wentzel & Makuya 1972: 147), Kinyarwanda (Sibomana 1974: 185), English (Pierrehumbert 1980), Japanese (Pierrehumbert & Beckman 1988: 75), Kinande (Hyman 1990: 114), Chichewa (Myers 1996), and German (Féry 1993: 73). Questions are also marked by raising of the pitch range and/or reduction of phrasal pitch downtrends, as in Lingala (Guthrie 1940), Kongo (Carter 1973), Danish (Thorsen 1978), Kikuyu (Clements & Ford 1981), Hausa (Inkelas & Leben 1990), Jita (Downing 1995), and Kipare (Herman 1996). Final low tones mark yes-no questions in languages such as Chickasaw (Gordon 2005), Akan (Genzel & Kügler, 2020), and the languages surveyed in Rialland (2009).…”
