Introduction

Shuo-yiin Chang is an accomplished inventor based in Mountain View, California, recognized for his contributions to the field of speech recognition. With a total of three patents under his name, Chang has made significant strides in enhancing the capabilities of Automatic Speech Recognition (ASR) systems, particularly in on-device applications.

Latest Patents

Chang's latest patents focus on innovative approaches to ASR technology. His first patent, titled "Two-pass end to end speech recognition," involves a two-pass automatic speech recognition model designed for streaming on-device ASR. This model generates text representations of utterances captured in audio data, utilizing a first-pass portion that employs a recurrent neural network transformer (RNN-T) decoder to produce streaming candidate recognitions. The second-pass portion of the model, featuring a listen attend spell (LAS) decoder, facilitates the revision of these recognition candidates, ultimately enhancing the accuracy of the text representation.

The second of his recent patents, "Joint endpointing and automatic speech recognition," describes a method that integrates speech decoding and endpointing within a singular speech recognition model. This process includes receiving audio data of an utterance and producing partial speech recognition results while also providing an endpoint indication to determine when the utterance has concluded. This streamlined approach allows for efficient processing of audio data and ensures accurate detection of utterance endings.
