The present article describes a corpus which was collected for the cross-language comparison of prominence. In the data analysis, the acoustic-phonetic properties of words spoken with two different levels of accentuation (de-accented and nuclear accented in non-contrastive narrow-focus) are examined in question-answer elicited sentences and iterative imitations (on the syllable ‘da’) produced by Bulgarian, Russian, French, German and Norwegian speakers (3 male and 3 female per language). Normalized parameter values allow a comparison of the properties employed in differentiating the two levels of accentuation. Across the five languages there are systematic differences in the degree to which duration, f0, intensity and spectral vowel definition change with changing prominence under different focus conditions. The link with phonological differences between the languages is discussed.
