Title: The Innovations of Andrew Ng: Pioneering Text-to-Speech and Speech Recognition Technologies

Introduction

Andrew Ng, a prominent figure in the field of artificial intelligence, is based in Mountain View, CA. With a remarkable portfolio consisting of four patents, Ng has significantly contributed to advancements in speech technologies. His work focuses on making systems both simpler and more effective through the innovative use of deep learning models.

Latest Patents

Among Ng's latest patents is his development of a real-time neural text-to-speech (TTS) system. This production-quality TTS system leverages deep neural networks and is constructed with five major building blocks: a segmentation model for locating phoneme boundaries, a grapheme-to-phoneme conversion model, a phoneme duration prediction model, a fundamental frequency prediction model, and an audio synthesis model. Notably, phoneme boundary detection is accomplished using deep neural networks with Connectionist Temporal Classification (CTC) loss, while a version of WaveNet serves as the audio synthesis model. This approach requires fewer parameters and facilitates faster training compared to traditional systems, contributing to greater efficiency in real-time inference.

Another significant patent focuses on deep learning models for speech recognition. Ng's approach presents state-of-the-art speech recognition systems developed through end-to-end deep learning methods. The model architecture is notably simpler than traditional systems, which rely on intricately engineered processing pipelines that often falter in noisy environments. Ng's system directly learns robust functions without the necessity for hand-designed components, which allows for improved performance even amid background noise and speaker variability. Innovations include a well-optimized recurrent neural network (RNN) training system utilizing multiple GPUs and novel data synthesis techniques that streamline the training process.
