Description

Weighted finite-state transducers can be built, combined, optimized, and searched from software that needs formal language or speech-processing algorithms. It is useful for developers and researchers working on NLP, speech recognition, text processing, or automata-based systems.

This is a developer library, not a desktop app. Validate models and weights carefully because small modeling errors can change decoding and search results.
