Overview of this book

Building and implementing deep learning (DL) is becoming a key skill for those who want to be at the forefront of progress.But with so much information and complex study materials out there, getting started with DL can feel quite overwhelming. Written by an AI thought leader, Deep Learning with PyTorch Lightning helps researchers build their first DL models quickly and easily without getting stuck on the complexities. With its help, you’ll be able to maximize productivity for DL projects while ensuring full flexibility – from model formulation to implementation. Throughout this book, you’ll learn how to configure PyTorch Lightning on a cloud platform, understand the architectural components, and explore how they are configured to build various industry solutions. You’ll build a neural network architecture, deploy an application from scratch, and see how you can expand it based on your specific needs, beyond what the framework can provide. In the later chapters, you’ll also learn how to implement capabilities to build and train various models like Convolutional Neural Nets (CNN), Natural Language Processing (NLP), Time Series, Self-Supervised Learning, Semi-Supervised Learning, Generative Adversarial Network (GAN) using PyTorch Lightning. By the end of this book, you’ll be able to build and deploy DL models with confidence.

Automatic speech recognition using Flash

Recognizing speech from an audio file is perhaps one of the most widely used applications of AI. It's part of smartphone speakers such as Alexa, as well as automatically generated captions for video streaming platforms such as YouTube, and also many music platforms. It can detect speech in an audio file and convert it into text. Detection of speech involves various challenges such as speaker modalities, pitch, and pronunciation, as well as dialect and language itself:

Figure 4.6 – A concept of automatic speech recognition

To train a model for Automatic Speech Recognition (ASR), we need a training dataset that is a collection of audio files along with the corresponding text transcription that describes that audio. The more diverse the set of audio files with people from different age groups, ethnicities, dialects, and so on is, the more robust the ASR model will be for the unseen audio files.
