ESCA Tutorial and Research Workshop on
This paper describes the approach taken at Chalmers University of Technology in building up an integrated multilevel speech database for the purpose of speech research and the development of speech coding techniques. The material comprises today isolated speech sounds (phones and diphones) as well as short, semantically unrelated sentences and coherent texts. Data collection is, to start with, restricted to Swedish material and read speech. Registration of the speech samples was carried out under optimal conditions (sound-insulated, unechoic studio) using digital recording equipment (SONY PCM-F1). Segmentation, classification and labeling is performed at eight interlacing levels of linguistic (including acoustic, phonetic and prosodic) analysis.
