itnpy2 0.0.7

A simple, deterministic, and extensible approach to inverse text normalization for numbers

A simple, deterministic, and extensible approach to inverse text normalization (ITN) for numbers.

Overview

This package converts raw spoken-form text (speech recognition output) into user-friendly written-form text. It works best for converting spoken numbers into numerical digits, or other translation tasks that do not modify word ordering. A csv file is provided to define the basic rules for transforming spoken tokens into written tokens, and extra pre/post-processing may be applied for more specific formatting requirements, i.e. dates, measurements, money, etc.
