Challenge: Existing models for emotion understanding do not capture fundamental features of synthesized speech.
Approach: They evaluate emotion recognition models on synthesized speech using SER models and generative models.
Outcome: The proposed model can't generalize to synthesized speech because of speech token prediction . generative models tend to infer emotion from textual semantics while ignoring paralinguistic cues.

Generative Error Correction for Emotion-aware Speech-to-text Translation (2025.findings-acl)

Copied to clipboard

Challenge: Despite recent advances in speech-to-text translation, the impact of the emotion content has been overlooked.
Approach: They propose to use generative error correction (GER) to generate the translation based on the decoded N-best hypotheses and combine emotion and sentiment labels into the LLM finetuning process to enable the model to consider the emotion content.
Outcome: The proposed model can translate speech in English-Chinese using GER and emotion and sentiment labels.
Automatic Dialogue Generation with Expressed Emotions (N18-2)

Copied to clipboard

Challenge: a growing interest in neural dialogue generation systems is focusing on generating human-like responses based on past utterances . despite efforts, few consider putting restrictions on the response itself . authors present three models that concatenate the desired emotion with the source input .
Approach: They propose three models that concatenate the desired emotion with the source input or push the emotion in the decoder.
Outcome: The proposed model is more efficient than the previous models, but it lacks the emotion vector.

Prompt-Guided Selective Masking Loss for Context-Aware Emotive Text-to-Speech (2025.findings-naacl)

Copied to clipboard

Challenge: Emotional dialogue speech synthesis (EDSS) aims to generate expressive speech by leveraging the dialogue context between interlocutors.
Approach: They propose a large language model to generate holistic emotion tags based on prior dialogue context and pinpoint key words in the target utterance that align with the predicted emotional state.
Outcome: The proposed method improves emotional expressiveness and facilitates automatic emotion speech generation during inference.
Textless Speech Emotion Conversion using Discrete & Decomposed Representations (2022.emnlp-main)

Copied to clipboard

Challenge: Existing methods for modifying emotion of speech are difficult because emotion affects all levels simultaneously.
Approach: They propose a method to convert a spoken language speech into a model of emotion . they use phonetic-content units, prosodic features, speaker, and emotion to modify the emotion a speech utterance has.
Outcome: The proposed method beats text-based systems in terms of perceived emotion and audio quality.
Modelling Context Emotions using Multi-task Learning for Emotion Controlled Dialog Generation (2021.eacl-main)

Copied to clipboard

Challenge: Recent research has tackled this task using neural generative methods by augmenting emotion classes with the input sequences.
Approach: They propose to use a self-attention based encoder and a decoder with dot product attention mechanism to generate a viable response with a specified emotion.
Outcome: The proposed model outperforms baselines on automatic evaluation measures such as F1 and BLEU scores, thus resulting in more fluent and adequate responses.
