Title: The Innovations of Gautam Tiwari

Introduction

Gautam Tiwari is a prominent inventor based in Boston, MA, known for his significant contributions to the field of speech processing. With a total of seven patents to his name, Tiwari has made remarkable advancements that enhance the functionality and efficiency of automatic speech recognition systems.

Latest Patents

One of Tiwari's latest patents focuses on endpointing in speech processing. This innovative speech-processing system determines potential endpoints in a user's speech by analyzing a stream of audio data. The system not only predicts these endpoints but also assigns an endpoint score that indicates the likelihood of the potential endpoint representing the end of speech. Once a potential endpoint is identified, the system publishes a transcript of the preceding speech and sends it to downstream components for further processing. This allows for continuous transcription and the determination of additional potential endpoints while the downstream components assess the completeness of the transcript. Final endpoint determinations are made based on the results of downstream processing, which may include automatic speech recognition and natural language understanding.

Another notable patent by Tiwari involves language and grammar model adaptation using model weight data. This system adapts a language model for automatic speech recognition for a new set of words without the need to retrain the entire ASR models. Instead, it modifies one grammar model to ensure compatibility with existing models in the ASR system, streamlining the adaptation process.
