Researchers have developed SAMPA, a new Transformer-based system for segmenting prosodic boundaries in Brazilian Portuguese speech. This system leverages the Whisper model, fine-tuned on the NURC-SP dataset, to insert explicit markers for prosodic boundaries. SAMPA demonstrates competitive performance, achieving an F1 score of 0.731 on a held-out test set and 0.796 on the MuPe-Diversidades dataset, indicating its effectiveness in capturing linguistic and acoustic cues.
