English Speak Reviewer

English Speak Reviewer is a practice platform built to simulate interview-style speaking scenarios and provide structured feedback on spoken responses. Users record audio directly in a browser-based studio, after which the audio is stored in object storage. A separate Python worker consumes jobs from a Redis-backed queue to perform speech processing tasks such as transcription and alignment using Whisper-based models. The system then derives fluency-related metrics, such as speaking rate and filler usage, and optionally generates narrative feedback to help users understand areas for improvement.
