APA: towards an Automatic Tool for Prosodic Analysis

In this paper a tool for the speech signal prosodic analysis is described. The system APA (Automatic Prosodic Analysis) is based on a tool for speech segmentation into syllabic units and on their description in terms of pitch, energy and duration. A particular linear stylization of the fundamental frequency function is proposed, which helps in describing efficiently intonation movements at phrase level. Finally the energy information, together with the f0 information, are used to find intonation boundary markers in order to segment speech into tone units. A general description of the tool is provided and recent results are reported. Future works in this field are also announced.
