Refinement Pipeline
Definition
A processing chain that transforms raw speech-to-text output into polished, formatted text using AI language models.
A refinement pipeline takes raw ASR output — which typically lacks punctuation, contains filler words, and has an informal structure — and transforms it into clean, well-formatted text suitable for its intended purpose. The pipeline may include multiple stages: text normalization, grammar correction, style adjustment, formatting, and final review.
Ummless implements a refinement pipeline that sends raw transcriptions to a language model along with preset-defined instructions. The model applies the specified transformations and returns refined text. Presets can be stacked, running the output of one refinement through another for multi-stage processing — for example, first cleaning up grammar, then formatting as an email.
