Description
Premove ITN is an open-source, context-aware inverse text normalizer built for voice agents. It turns messy ASR transcripts into structured values APIs can actually use: phone numbers, dates, times, amounts, IDs, emails, URLs, and more. Instead of generating normalized text directly, it deterministically produces valid candidates, uses a neural model to score them in sentence context, and applies exact decoding to choose compatible outputs. Open weights, Python package, real-time inference.

Could you build this?
Partial Inverse text normalization (ITN) across diverse entity types requires sophisticated deterministic weighted finite-state transducers (WFSTs) or specialized grammar rules to avoid LLM hallucinations.
What it would actually take: Production ITN engines (like NeMo ITN or Thrax) rely on Weighted Finite-State Transducers (WFSTs) compiled with OpenFst, or custom grammar-based AST parsers. The system requires rule-based grammar engineering across numbers, currencies, dates, alphanumeric codes, and phonetics to ensure 100% deterministic, low-latency (<5ms) token transformation before passing data to voice agent tools. Deep computational linguistics expertise and test suites covering tens of thousands of edge cases are required.
