The Northern Vietnamese dialect is known to involve laryngeal configuration as an integral part of its tonal system. This work analyses the relationship between pitch and voice quality in another variety of Vietnamese spoken in the North-Central region, named Lam River Speech. Acoustic data of fundamental frequency (F0) and duration in the citation form of their unstopped tones is presented in the form of mean F0 time-course; and voice quality is determined by perceptual observation of ten female speakers. Normalised mean F0 and various voice qualities are discussed from viewpoints of both between-speaker and within-speaker differences. The within-speaker variation points to the fact that the degree of laryngealisation is correlated with relative pitch of a speaker. Intrinsic vowel F0 data supports this fact, where laryngealisation is likely to occur in low vowels that carry lower F0. It is concluded that pitch is a primary cue in the LRS tonal system, whereas laryngealisation is a secondary one. Ultimately, this usage of laryngealisation is different from the well-studied Northern Vietnamese dialect.
