A production study on read German speech shows an increase in prominence-lending parameters as the focus domain is narrowed, or when contrast is expressed over non-contrast. Prominence-lending parameters included tonal and durational cues (e.g. nuclear pitch accent type and scaling, duration of segments and syllables) as well as those generally considered to be in the segmental domain (e.g. formant values of vowels in nuclear syllables). These cues are exploited by different speakers to different degrees and in different combinations, but are all used for signalling aspects of focus.
