| Challenge: | Current speech encoding pipelines rely on an additional text-based LM to get robust representations of human communication, even though speech-to-text models often have a LM within. |
| Approach: | They propose to align Whisper's latent space with semantic representations from a text autoencoder and lexically derived embeddings of basic psychological dimensions: emotion and personality. |
| Outcome: | The proposed approach surpasses current speech encoders over self-supervised affective tasks and downstream psychological tasks, achieving an error reduction of 73.4% and 83.8%, respectively. |

| Challenge: | a longitudinal model for NLP relies on document-level evaluation to map isolated instances of language to an outcome. |
| Approach: | They propose a longitudinal model that aligns evaluation splits to generalization over people and time . they propose integrating a sequence inputs to incorporate history by default . |
| Outcome: | The proposed model improves on a dataset of 17k daily diary transcripts paired with PTSD symptom severity from 238 participants. |
