• Title: A Stutter Seldom Comes Alone -- Cross-Corpus Stuttering Detection as a Multi-label Problem
• Abstract summary: This paper explores multi-language and cross-corpus end-to-end stuttering detection as a multi-label problem. We evaluate a modified wav2vec 2.0 system with an attention-based classification head and multi-task learning. The experimental results and an error analysis show that multi-label stuttering detection systems trained on cross-corpus and multi-language data achieve competitive results.

• Abstract: Most stuttering detection and classification research has viewed stuttering as a multi-class classification problem or a binary detection task for each dysfluency type; however, this does not match the nature of stuttering, in which one dysfluency seldom comes alone but rather co-occurs with others. This paper explores multi-language and cross-corpus end-to-end stuttering detection as a multi-label problem using a modified wav2vec 2.0 system with an attention-based classification head and multi-task learning. We evaluate the method using combinations of three datasets containing English and German stuttered speech, one containing speech modified by fluency shaping. The experimental results and an error analysis show that multi-label stuttering detection systems trained on cross-corpus and multi-language data achieve competitive results but performance on samples with multiple labels stays below over-all detection results.

  It is common practice in text classification to only use one majority label for model training even if a dataset has been annotated by multiple annotators. This paper proposes three strategies to leverage annotator disagreement for text classification: a probability-based multi-label method, an ensemble system, and instruction tuning.

• Large Language Models for Dysfluency Detection in Stuttered Speech [16.812800649507302]
  Accurately detecting dysfluencies in spoken language can help to improve the performance of automatic speech and language processing components. Inspired by the recent trend towards the deployment of large language models (LLMs) as universal learners and processors of non-lexical inputs, we approach the task of multi-label dysfluency detection as a language modeling problem. We present hypotheses candidates generated with an automatic speech recognition system and acoustic representations extracted from an audio encoder model to an LLM, and finetune the system to predict dysfluency labels on three datasets containing English and German stuttered speech.

  This paper focuses on reducing noise based on some inherent properties of multi-label classification and long-tailed learning under noisy cases. We propose a Stitch-Up augmentation to synthesize a cleaner sample, which directly reduces multi-label noise. A Heterogeneous Co-Learning framework is further designed to leverage the inconsistency between long-tailed and balanced distributions.

  We propose Transformer-based encoder-decoder models that jointly solve speech recognition and disfluency detection. Compared to pipeline approaches, the joint models can leverage acoustic information that makes disfluency detection robust to recognition errors. We show that the proposed joint models outperformed a BERT-based pipeline approach in both accuracy and latency.

  Quantification, variously called "labelled prevalence estimation" or "learning to quantify", is the supervised learning task of generating predictors of the relative frequencies of the classes of interest in unsupervised data samples. We propose methods for inferring estimators of class prevalence values that strive to leverage the dependencies among the classes of interest in order to predict their relative frequencies more accurately.

We investigate the issue of label imbalance of hate speech datasets, since the high ratio of non-hate examples compared to hate examples often leads to low model performance.

  We propose a simple method to derive 2D representation from detection scores produced by an arbitrary set of binary classifiers. Based upon rank correlations, our method facilitates a visual comparison of classifiers with arbitrary scores. While the approach is fully versatile and can be applied to any detection task, we demonstrate the method using scores produced by automatic speaker verification and voice anti-spoofing systems.
