Title: Xiaozheng Shen and Far-Field Speech Interaction
Introduction
Xiaozheng Shen is an inventor associated with Shanghai, China, and Espressif Systems (Shanghai) Pte Ltd. Her patent work addresses how smart devices can improve speech interaction when users are speaking from a distance.
Latest Patents
Shen is named on 1 patent: “Method for Improving Far-Field Speech Interaction Performance, and Far-Field Speech Interaction System.” The invention describes a smart device that uses soundwave signals during network configuration to estimate the acoustic conditions of its surroundings. It tests spatial acoustic parameter values, adjusts front-end speech-processing settings, and compares the resulting signal energy to identify a suitable final parameter. A speech-recognition engine then uses that parameter to select an acoustic model trained on data with similar acoustic conditions.
Career Highlights
The patent reflects work on adapting speech-recognition systems to the acoustic environment around a smart device. By selecting processing settings and a recognition model based on measured conditions, the method aims to improve far-field speech interaction.
Collaborations
The patent lists Xiaozheng Shen as an inventor and Espressif Systems (Shanghai) Pte Ltd as the associated company. The provided information does not identify additional inventors or collaborators.
Conclusion
Xiaozheng Shen’s patent focuses on tailoring speech processing and acoustic-model selection to a device’s surroundings, supporting more effective far-field voice interaction.
