In the realm of speech-to-text (STT) technology, achieving high accuracy and efficiency on low-power devices like the Raspberry Pi Zero 2W presents a unique challenge. This report delves into the performance of the VOST STT system when processing simple English language dialogs on such a device. We will explore the issues encountered, particularly the problem of repeated text at the end of buffers, and propose solutions to enhance the system’s performance.
