Introduction

Junho Park is an accomplished inventor based in Bedford, MA (US). He has made significant contributions to the field of automatic speech recognition, holding two patents that showcase his innovative approach to technology.

Latest Patents

One of Junho Park's latest patents is an end-to-end automatic speech recognition system designed for both conversational and command-and-control speech. This system includes an audio encoder that processes input audio signals to produce encoded audio signals. It also features a bias encoder that generates bias entries corresponding to words for improved recognition by the ASR system. Additionally, a transcription token probability prediction network predicts the probability of selected transcription tokens based on the outputs of both the bias encoder and the audio encoder. The system employs two attention mechanisms to ensure that the transcription process is contextually appropriate.

Another notable patent is a system and method for secure training of speech processing systems. This invention involves generating an obscured speech signal from an input speech signal and an obscured transcription from the input speech signal's transcription. The method includes extracting a speaker embedding from the input speech signal and generating a synthetic speech signal using this embedding. The training of the speech processing system utilizes the obscured transcription, synthetic speech signal, and other components to enhance security and efficiency.
