Abstract

One of the key bottlenecks in training diverse accurate audio classifiers is the need for “strongly-labeled” training data, that provide precisely demarcated instances of the audio events to be recognized. Such data are, however, difficult to obtain, particularly in bulk. The alternate, more popular approach is to train models using “weakly” labelled data, comprising recordings in which only the presence or absence of sound classes is tagged, without additional details of the number of occurrences of the sounds or their locations in the recordings. Weakly labelled data are much easier to obtain than strongly labelled data; however training with such data comes with many challenges. In this tutorial we will discuss the problem of training audio (and other) classifiers from weakly labelled data, including several state-of-art formalisms, their restrictions and limitations, and areas of future research.

Abstract

In recent years, reinforcement learning and bandits have transformed a wide range of real-world applications including healthcare, finance, recommendation systems, robotics and computer vision, and last but not least, the speech and language processing. While most speech and language applications of reinforcement learning algorithms are centered around improving deep network training with its flexible optimization properties, there are still many grounds to explore to utilize the benefits of reinforcement learning, such as its reward-driven adaptability, state representations, temporal structures, and generalizability. In this one-session tutorial, we will overview the recent advancements of reinforcement learning and bandits and discuss how they can be employed to solve various speech and natural language processing problems with models that are interpretable and scalable.

Abstract

Although Deep Learning models have revolutionized the speech and audio processing field, they build specialist models for individual tasks and application scenarios. Deep neural models also bottlenecked dialects and languages with limited labelled data. Self-supervised representation learning methods promise a single universal model to benefit a collection of tasks and domains. They recently succeeded in NLP and computer vision domains, reaching new performance levels while reducing required labels for many downstream scenarios. Speech representation learning is experiencing similar progress with three main categories: generative, contrastive, and predictive. Other approaches relied on multi-modal data for pre-training, mixing text or visual data streams with speech. Although self-supervised speech representation is still a developing research area, it is closely related to acoustic word embedding and learning with zero lexical resources. This tutorial session will present self-supervised speech representation learning approaches and their connection to related research areas. Since many current methods focus solely on automatic speech recognition as a downstream task, we will review recent efforts on benchmarking learned representations to extend the application of such representations beyond speech recognition. A hands-on component of this tutorial will provide practical guidance on building and evaluating speech representation models.

Abstract

Cochlear implantation, as one of the most profound technological advances in modern medicine, is able to restore partial hearing and speech communication abilities to a large amount of profoundly deaf people. Cochlear implants (CIs) provide a valuable scientific model to investigate the impacts of psychoacoustic and linguistic cues on speech perception. Understanding speech in noisy environments remains challenging for most CI users; hence speech enhancement plays an extremely important role for CI speech processing and perception. Innovations from psychoacoustic knowledge to recent machine learning technology may provide novel solutions for the design of CI speech enhancement methods in challenging listening tasks.

Abstract

The tutorial introduces recent advancements in the emerging field of personalized speech enhancement. Personalizing a speech enhancement model leads to a compressed, thus efficient machine learning inference because the model focuses on a particular user’s speech characteristics or their acoustic environment rather than trying to solve the general-purpose enhancement task. Since the test-time task can be seen as a smaller sub-problem of the generic speech enhancement problem, the model can also achieve better performance by solving a smaller and easier optimization problem. Moreover, since the goal is to adapt to the unseen test environment, personalization can improve the fairness of AI models for the users who are not well represented in the big training data.  Meanwhile, personalized speech enhancement is challenging as it is difficult to utilize the personal information (e.g., clean speech) of the unknown test-time users ahead of time. In addition, acquiring such private data can increase concerns about privacy issues in speech applications. In this tutorial, we will explore various definitions of personalized speech enhancement in the literature and relevant machine learning concepts, such as zero- or few-shot learning approaches, data augmentation and purification, self-supervised learning, knowledge distillation, and domain adaptation. We will also see how these methods can improve data and resource efficiency in machine learning while achieving desired speech enhancement performance.

Abstract

Neural models have become ubiquitous in speech technologies - almost all state-of-the-art speech technologies use deep learning as their foundation. This has made it possible for all applications to be built on top of a neural network library. This possibility is currently coming to fruition in the PyTorch ecosystem of speech technologies. This diverse landscape includes, for example, the automatic differentiation capable weighted finite state models in K2 and GTN, the powerful speech representations learned by pretrained wav2vec 2.0 models in Fairseq and Transformers, and the models, data loading and recipes in a large variety of tasks implemented by toolkits like ESPnet, NeMo, Asteroid and SpeechBrain, as well as a wealth of other tools such as the metric learning criteria of PyTorch Metric Learning. The first chapter of the tutorial covers PyTorch fundamentals and interfaces, and the subsequent chapters look at different practical challenges and tools that address them.
