A Praat script that transcribes European Portuguese intonation using P_ToBI system. Check the 2024 Speech Prosody poster and short paper at the proceedings.
A rule-based Praat script designed to generate P-ToBI labels based on the pitch contour given a tier with by-syllable intervals and stress marks. The system was trained on a 96-sentence corpus comprising all Nuclear Pitch Accents (NPA) and Boundary Tones (BT) in European Portuguese (EP). Evaluation was conducted on a separate corpus of 146 sentences showing a success rate of 73.8% (k=0.6) for NPA and 78.7% for BT (k=0.6).
The qualitative analysis of errors, excluding those stemming from the pitch tracking algorithm, exposes challenges in accurately identifying falling NPAs, particularly instances of L*, H*+L, and H+L* followed by a low BT.
