Rhythm and Pitch contains approximately 27 minutes of spontaneous English conversations and radio news stories annotated with the Rhythm and Pitch (RaP) scheme. Speech data for annotation was taken from two corpora released by LDC, CALLHOME American English Speech (LDC97S42) and Boston University Radio Speech Corpus (LDC96S36).

The RaP system permits the capture of both intonational and rhythmic aspects of speech. Four labeling tiers are used for annotating speech prosody. These tiers carry information about the syllabic organization and orthography of the speech, its rhythmic structure, tonal patterns, and other information. More information about the RaP system is available on the RaP homepage.


Speech data are presented as flac compressed 16-bit wav files. The Boston data are one channel 16kHz files, while the CALLHOME data are either one or two channel 8kHz files. Annotations are UTF-8 encoded Praat TextGrids.
