IP length and peak (and valley) trends in neutral declaratives in Connaught and Ulster Irish – a comparison

Maria O'Reilly, Ailbhe Ní Chasaide


This paper explores the influence of IP (i.e. Intonational Phrase) length on the scaling of the IP-initial and IP-final tonal targets – peaks (and valleys) in three Irish dialects. The analysis covers a set of matched neutral (i.e. broad focus) declaratives of two IP lengths (with 2 and 3 accent groups, respectively) produced by native speakers of two Connaught dialects, C-CF and C-IM and the Ulster dialect of U-GD. The data was analysed for H and L tone scaling in the phrase-initial and final accents. Additionally, the ratio of the final to the initial peak height was calculated (and the final to initial L height in the case of the U-GD dialect). The results show little to no influence of IP length in the Connaught dialects on any of the peak metrics. However, for the U-GD dialect there is a strong influence of IP length on the initial accent (L*+H) where both the L* and H elements are substantially raised. The final accent behaves rather differently being remarkably invariant in both IP length conditions.
