| 2026 | AMuSeD: An Attentive Deep Neural Network for Multimodal Sarcasm Detection Incorporating Bimodal Data AugmentationabstractDetecting sarcasm effectively requires a nuanced understanding of context, including vocal tones and facial expressions. The progression towards multimodal computational methods in sarcasm detection, however, faces challenges due to the scarcity of data. To address this, we present AMuSeD (Attentive deep neural network for MUltimodal Sarcasm dEtection incorporating bi-modal Data augmentation). This approach utilizes the Multimodal Sarcasm Detection Dataset (MUStARD) and introduces a two-phase bimodal data augmentation strategy. The first phase involves generating varied text samples through Back-Translation from several secondary languages. The second phase involves the refinement of a FastSpeech2-based speech synthesis system, tailored specifically for sarcasm to retain sarcastic intonations. Alongside a cloud-based Text-to-Speech (TTS) service, this Fine-tuned FastSpeech2 system produces corresponding audio for the text augmentations. We also evaluate various attention mechanisms for selectively enhancing sarcasm-relevant features, finding self-attention to be the most efficient. Our experiments reveal that the proposed approach achieves a significant F1-score of 81.0% in text-audio modalities, surpassing even models that use three modalities from the MUStARD dataset.

| 2025 | Enhancing Standard and Dialectal Frisian ASR: Multilingual Fine-tuning and Language Identification for Improved Low-resource PerformanceabstractAutomatic Speech Recognition (ASR) performance for low-resource languages is still far behind that of higher-resource languages such as English, due to a lack of sufficient labeled data. State-of-the-art methods deploy self-supervised transfer learning where a model pre-trained on large amounts of data is fine-tuned using little labeled data in a target low-resource language. In this paper, we present and examine a method for fine-tuning an SSL-based model in order to improve the performance for Frisian and its regional dialects (Clay Frisian, Wood Frisian, and South Frisian). We show that Frisian ASR performance can be improved by using multilingual (Frisian, Dutch, English and German) fine-tuning data and an auxiliary language identification task. In addition, our findings show that performance on dialectal speech suffers substantially, and, importantly, that this effect is moderated by the elicitation approach used to collect the dialectal data. Our findings also particularly suggest that relying solely on standard language data for ASR evaluation may underestimate real-world performance, particularly in languages with substantial dialectal variation.

| 2025 | Intra-modal Relation and Emotional Incongruity Learning using Graph Attention Networks for Multimodal Sarcasm DetectionabstractSarcasm detection poses unique challenges due to the complex nature of sarcastic expressions often embedded across multiple modalities. Current methods frequently fall short in capturing the incongruent emotional cues that are essential for identifying sarcasm in multimodal contexts. In this paper, we present a novel method to capture the pair-wise emotional incongruities between modalities through a cross-modal Contrastive Attention Mechanism (CAM), leveraging advanced data augmentation techniques to enhance data diversity and Supervised Contrastive Learning (SCL) to obtain discriminative embeddings. Additionally, we employ Graph Attention Networks (GATs) to construct modality-specific graphs, capturing intra-modal dependencies. Experiments conducted on the MUStARD++ dataset demonstrate the efficacy of our approach, achieving a macro F1 score of 74.96%, which outperforms state-of-the-art methods.

| 2025 | A Multimodal Chinese Dataset for Cross-lingual Sarcasm DetectionabstractSarcasm is expressed through subtle cues like pitch, speech rate, and facial expressions, with patterns varying across languages, e.g., English speakers lower the pitch while Cantonese speakers raise it. While humans readily interpret these signals, computational models struggle, creating challenges for Human-Machine Interaction. Most multimodal sarcasm recognition research focuses on English and the lack of high-quality datasets for other languages hinders cross-lingual and cross-cultural studies. We introduce the Multimodal Chinese Sarcasm Dataset (MCSD), containing 10.57 hours of video. We propose a standardized annotation framework that captures annotator certainty to reflect the subjectivity of sarcasm, achieving a Fleiss'kappa of 0.74 (unweighted) and 0.79 (certainty-weighted). Validation of our dataset using SVM achieves a 76.64% F1-score in sarcasm detection. MCSD lays the foundation for robust cross-lingual sarcasm detection, contributing to advanced, human-centric systems. Xiyuan Gao, Bruce Xiao Wang, Shuming Huang, Shekhar Nayak, Matt Coler |

| 2025 | Leveraging Large Language Models for Sarcastic Speech Annotation in Sarcasm DetectionabstractSarcasm fundamentally alters meaning through tone and context, yet detecting it in speech remains a challenge due to data scarcity. In addition, existing detection systems often rely on multimodal data, limiting their applicability in contexts where only speech is available. To address this, we propose an annotation pipeline that leverages large language models (LLMs) to generate a sarcasm dataset. Using a publicly available sarcasm-focused podcast, we employ GPT-4o and LLaMA 3 for initial sarcasm annotations, followed by human verification to resolve disagreements. We validate this approach by comparing annotation quality and detection performance on a publicly available sarcasm dataset using a collaborative gating architecture. Finally, we introduce PodSarc, a large-scale sarcastic speech dataset created through this pipeline. The detection model achieves a 73.63% F1 score, demonstrating the dataset's potential as a benchmark for sarcasm detection research. Yuqing Zhang 0003, Xiyuan Gao, Shekhar Nayak, Matt Coler |

| 2025 | Overcoming Data Scarcity in Multi-Dialectal Arabic ASR via Whisper Fine-TuningabstractAlthough commercial Arabic automatic speech recognition (ASR) systems support Modern Standard Arabic (MSA), they struggle with dialectal speech. We investigate the effect of fine-tuning OpenAI's Whisper on five major Arabic dialects (Gulf, Levantine, Iraqi, Egyptian, Maghrebi) using Mozilla Common Voice for MSA and the MASC dataset for dialectal speech. We evaluate MSA training size effects, benefits of pre-training on MSA data, and dialect-specific versus dialect-pooled models. We find that small amounts of MSA fine-tuning data yield substantial improvements for smaller models, matching larger non-fine-tuned models. While MSA pre-training shows minimal benefit, suggesting limited shared features between MSA and dialects, our dialect-pooled models perform comparably to dialect-specific ones. This indicates that pooling dialectal data, when properly balanced, can help address data scarcity in low-resource ASR without significant performance loss.

| 2025 | Spoken in Jest, Detected in Earnest: A Systematic Review of Sarcasm Recognition - Multimodal Fusion, Challenges, and Future ProspectsabstractSarcasm, a common feature of human communication, poses challenges in interpersonal interactions and human-machine interactions. Linguistic research has highlighted the importance of prosodic cues, such as variations in pitch, speaking rate, and intonation, in conveying sarcastic intent. Although previous work has focused on text-based sarcasm detection, the role of speech data in recognizing sarcasm has been underexplored. Recent advancements in speech technology emphasize the growing importance of leveraging speech data for automatic sarcasm recognition, which can enhance social interactions for individuals with neurodegenerative conditions and improve machine understanding of complex human language use, leading to more nuanced interactions. This systematic review is the first to focus on speech-based sarcasm recognition, charting the evolution from unimodal to multimodal approaches. It covers datasets, feature extraction, and classification methods, and aims to bridge gaps across diverse research domains. The findings include limitations in datasets for sarcasm recognition in speech, the evolution of feature extraction techniques from traditional acoustic features to deep learning-based representations, and the progression of classification methods from unimodal approaches to multimodal fusion techniques. In so doing, we identify the need for greater emphasis on cross-cultural and multilingual sarcasm recognition, as well as the importance of addressing sarcasm as a multimodal phenomenon, rather than a text-based challenge.

| 2024 | Fine-Tuning Strategies for Dutch Dysarthric Speech Recognition: Evaluating the Impact of Healthy, Disease-Specific, and Speaker-Specific DataabstractDespite significant advancements in automatic speech recognition technology (ASR) the performance of such systems on dysarthric speech is still inadequate for widespread use. One key reason is the lack of sufficiently rich and diverse dysarthric speech datasets to train machine learning models that could handle all types and varieties of such speech. Motivated by the data scarcity problem, as well as by successful applications of self-supervised learning (SSL) in ASR for low-resource languages, this paper investigates and evaluates the effectiveness of three different data-centric SSL training strategies in improving Dutch dysarthric speech recognition. The first strategy involves fine-tuning with both dysarthric and healthy speech data, the second with disease-specific data and the third with speaker-specific data. The first and third strategies are proven effective, while the second one, though ineffective, provides valuable insights for further research.

| 2024 | A Functional Trade-off between Prosodic and Semantic Cues in Conveying SarcasmabstractThis study investigates the acoustic features of sarcasm and disentangles the interplay between the propensity of an utterance being used sarcastically and the presence of prosodic cues signaling sarcasm. Using a dataset of sarcastic utterances compiled from television shows, we analyze the prosodic features within utterances and key phrases belonging to three distinct sarcasm categories (embedded, propositional, and illocutionary), which vary in the degree of semantic cues present, and compare them to neutral expressions. Results show that in phrases where the sarcastic meaning is salient from the semantics, the prosodic cues are less relevant than when the sarcastic meaning is not evident from the semantics, suggesting a trade-off between prosodic and semantic cues of sarcasm at the phrase level. These findings highlight a lessened reliance on prosodic modulation in semantically dense sarcastic expressions and a nuanced interaction that shapes the communication of sarcastic intent.

| 2023 | The Effects of Input Type and Pronunciation Dictionary Usage in Transfer Learning for Low-Resource Text-to-SpeechabstractWe compare phone labels and articulatory features as input for cross-lingual transfer learning in text-to-speech (TTS) for low-resource languages (LRLs). Experiments with FastSpeech 2 and the LRL West Frisian show that using articulatory features outperformed using phone labels in both intelligibility and naturalness. For LRLs without pronunciation dictionaries, we propose two novel approaches: a) using a massively multilingual model to convert grapheme-to-phone (G2P) in both training and synthesizing, and b) using a universal phone recognizer to create a makeshift dictionary. Results show that the G2P approach performs largely on par with using a ground-truth dictionary and the phone recognition approach, while performing generally worse, remains a viable option for LRLs less suitable for the G2P approach. Within each approach, using articulatory features as input outperforms using phone labels. Phat Do, Matt Coler, Jelske Dijkstra, Esther Klabbers |

| 2023 | Resource-Efficient Fine-Tuning Strategies for Automatic MOS Prediction in Text-to-Speech for Low-Resource LanguagesabstractWe train a MOS prediction model based on wav2vec 2.0 using the open-access data sets BVCC and SOMOS. Our test with neural TTS data in the low-resource language (LRL) West Frisian shows that pre-training on BVCC before fine-tuning on SOMOS leads to the best accuracy for both fine-tuned and zero-shot prediction. Further fine-tuning experiments show that using more than 30 percent of the total data does not lead to significant improvements. In addition, fine-tuning with data from a single listener shows promising system-level accuracy, supporting the viability of one-participant pilot tests. These findings can all assist the resource-conscious development of TTS for LRLs by progressing towards better zero-shot MOS prediction and informing the design of listening tests, especially in early-stage evaluation.

| 2022 | Deep CNN-based Inductive Transfer Learning for Sarcasm Detection in SpeechabstractSarcasm is a frequently used linguistic device which is expressed in a multitude of ways, both with acoustic cues (including pitch, intonation, intensity, etc.) and visual cues (including facial expression, eye gaze, etc.). While cues used in the expression of sarcasm are well-described in the literature, there is a striking paucity of attempts to perform automatic sarcasm detection in speech. To explore this gap, we elaborate a methodology of implementing Inductive Transfer Learning (ITL) based on pre-trained Deep Convolutional Neural Networks (DCNNs) to detect sarcasm in speech. To those ends, the multimodal dataset MUStARD is used as a target dataset in this study. The two selected pre-trained DCNN models used are Xception and VGGish, which we trained on visual and audio datasets. Results show that VGGish, which is applied as a feature extractor in the experiment, performs better than Xception, which has its convolutional layers and pooling layers retrained. Both models achieve a higher F-score compared to the baseline Support Vector Machines (SVM) model by 7% and 5% in unimodal sarcasm detection in speech. Xiyuan Gao, Shekhar Nayak, Matt Coler |

| 2022 | UniMorph 4.0: Universal MorphologyabstractThe Universal Morphology (UniMorph) project is a collaborative effort providing broad-coverage instantiated normalized morphological inflection tables for hundreds of diverse world languages. The project comprises two major thrusts: a language-independent feature schema for rich morphological annotation, and a type-level resource of annotated data in diverse languages realizing that schema. This paper presents the expansions and improvements on several fronts that were made in the last couple of years (since McCarthy et al. (2020)). Collaborative efforts by numerous linguists have added 66 new languages, including 24 endangered languages. We have implemented several improvements to the extraction pipeline to tackle some issues, e.g., missing gender and macrons information. We have amended the schema to use a hierarchical structure that is needed for morphological phenomena like multiple-argument agreement and case stacking, while adding some missing morphological features to make the schema more inclusive. In light of the last UniMorph release, we also augmented the database with morpheme segmentation for 16 languages. Lastly, this new release makes a push towards inclusion of derivational morphology in UniMorph by enriching the data and annotation schema with instances representing derivational processes from MorphyNet.

| 2022 | Improving Luxembourgish Speech Recognition with Cross-Lingual Speech RepresentationsabstractLuxembourgish is a West Germanic language spoken by roughly 390,000 people, mainly in Luxembourg. It is one of Europe's under-described and under-resourced languages, not extensively investigated in the context of speech recognition. We explore the self-supervised multilingual learning of Luxembourgish speech representations for the speech recognition downstream task. We show that learning cross-lingual representations is essential for low-resourced languages such as Luxembourgish. Learning cross-lingual representations and rescoring the output transcriptions with language modelling while using only 4 hours of labelled speech achieves a word error rate of 15.1% and improves our Transfer Learning baseline model relatively by 33.1% and absolutely by 7.5%. Increasing the amount of labelled speech to 14 hours yields a significant performance gain resulting in a 9.3% word error rate.11Models and datasets are available at https://hugging£ace.co/lemswasabi Le Minh Nguyen 0002, Shekhar Nayak, Matt Coler |

| 2021 | A Systematic Review and Analysis of Multilingual Data Strategies in Text-to-Speech for Low-Resource LanguagesabstractWe provide a systematic review of past studies that use multilingual data for text-to-speech (TTS) of low-resource languages (LRLs). We focus on the strategies used by these studies for incorporating multilingual data and how they affect output speech quality. To investigate the difference in output quality between corresponding monolingual and multilingual models, we propose a novel measure to compare this difference across the included studies and their various evaluation metrics. This measure, called the Multilingual Model Effect (MLME), is found to be affected by: acoustic model architecture, the difference ratio of target language data between corresponding multilingual and monolingual experiments, the balance ratio of target language data to total data, and the amount of target language data used. These findings can act as reference for data strategies in future experiments with multilingual TTS models for LRLs. Language family classification, despite being widely used, is not found to be an effective criterion for selecting source languages. Phat Do, Matt Coler, Jelske Dijkstra, Esther Klabbers |

| 2021 | Evolving Plasticity for Autonomous Learning under Changing Environmental ConditionsabstractA fundamental aspect of learning in biological neural networks is the plasticity property which allows them to modify their configurations during their lifetime. Hebbian learning is a biologically plausible mechanism for modeling the plasticity property in artificial neural networks (ANNs), based on the local interactions of neurons. However, the emergence of a coherent global learning behavior from local Hebbian plasticity rules is not very well understood. The goal of this work is to discover interpretable local Hebbian learning rules that can provide autonomous global learning. To achieve this, we use a discrete representation to encode the learning rules in a finite search space. These rules are then used to perform synaptic changes, based on the local interactions of the neurons. We employ genetic algorithms to optimize these rules to allow learning on two separate tasks (a foraging and a prey-predator scenario) in online lifetime learning settings. The resulting evolved rules converged into a set of well-defined interpretable types, that are thoroughly discussed. Notably, the performance of these rules, while adapting the ANNs during the learning tasks, is comparable to that of offline learning methods such as hill climbing.
