The C-ORAL-ROM book and DVD provide a unique set of comparable corpora of spontaneous speech for the main Romance languages, French, Italian, Portuguese and Spanish. The corpora are accompanied by comparative linguistic studies, models and standard linguistic measures of spoken language variability. Each corpus is built to the same design using identical sampling techniques, and each corpus is presented in multimedia format, allowing simultaneous access to aligned acoustic and textual information. Texts are headed with information about provenance, participants, etc. and the transcriptions show changes of speaker. Speech acts are tagged according to the evidence of prosodic criteria. Each corpus totals 300,000 words and presents formal and informal speech in a variety of contexts of use, dialogue structure and text genres, semantic domains and speech act typologies.
