1. Languages such as Southern Barasano “do not have the consonantal contrast between nasal and non-nasal segments but between voiced and voiceless ones” (Piggott 1992: 47). Piggott (1992: 49) proposes that all voiced segments in the consonant system of such languages, including the prenasalized stops, are sonorants -> the voiced-voiceless distinction in this type of systems is a contrast between sonorants and non-sonorants.2. Spontaneous Voicing (SV-node), “ is an alternate label for the feature [sonorant]”. It is “a vocal tract configuration in which the vocal cords vibrate in response to the passage of air” (Piggott 1992: 48).
