Intrinsic Fundamental Frequency in Intrinsic Fundamental Frequency in Igbo

Intrinsic Fundamental Frequency (IF0) is a phenomenon that reveals a correlation between vowel height and fundamental frequency whereby high vowels produce higher F0 than low vowels.  Some reports in the literature consider IF0 to be universal (Whalen and Levitt, 1995), though Connell’s (2002) study reports a neutralization of IF0 in Mambila. This paper studies this phenomenon as it concerns Ìgbò, a west Benue-Congo tone language spoken predominantly in the southeastern part of Nigeria. Ìgbò has eight phonemic vowels, /a e i ɪ o ɔ u ʊ /, which follow a two-tone system, high and low. In an attempt to establish the existence or otherwise of IF0 in Ìgbò, this paper examines the correlation between phonemic vowel height and fundamental frequency. Results confirm the existence of IF0 in the languagebearing on a positive correlation between pitch and vowel height. It is further shown that IF0 is generally reduced for low tone.

La fréquence fondamentale intrinsèque (F0I) est un phénomène qui dévoile une corrélation entre la hauteur de la voyelle et la fréquence fondamentale par laquelle les voyelles hautes produisent une Fo plus élevée que celle des voyelles basses. Certains rapports dans la littérature considèrent FFI comme universelle (Whalen et Levitt 1995) bien que l’étude de Connell (2002) rapporte une neutralisation de FFI en Mambila. Cet article étudie ce phénomène par rapport à l’igbó, une langue à ton du Benue-Congo occidental parlée surtout dans la partie sud-est du Nigéria. La langue igbó a huit phonèmes vocaliques / a e i ɪ o ɔ u ʊ /, qui s’articulent autour d’un système de deux tons, le Haut et le Bas. En vue d’établir l’existence ou non de FFI en igbó, cet article examine la corrélation entre la hauteur de la voyelle phonémique et la fréquence fondamentale. Les résultats confirment l’ existence du F0I dans la langue s’appuyant sur une corrélation positive entre la hauteur du son et la hauteur de la voyelle. L’article montre en outre que la F0I est généralement réduite pour le ton bas.
