[Speaker] Mariana Julião (INESC-ID/IST)

Mariana Julião is a Postdoctoral Researcher at INESC-ID in Lisbon.
Mariana's research focuses on prosody, second language (L2) learning,
and L2 prosody, spanning from representations of prosody, to perception
and to the generation of prosody references from text. More recently,
Mariana has been involved in the development of data resources and
state-of-the-art models for ASR of European Portuguese.

[Abstract]

Prosody has gained increasing attention in Computer-Assisted Language
Learning (CALL), yet it remains underemphasized in broader language
education. A major limitation of many CALL systems is their reliance on
imitation-based assessment, which primarily evaluates how closely
learners mimic native speakers rather than their actual prosodic
competence. Furthermore, these systems often fail to provide actionable
feedback, leaving learners aware of their performance level but without
clear guidance on how to improve.

In this presentation, we will discuss these challenges and explore
potential solutions, leveraging state-of-the-art methods in speech
processing.
