Inverse Text Normalization: Weighted Finite State Transducer

Model Overview

This model is an OpenFST finite state archive (.far) for use within the opensource Sparrowhawk normalization engine [2]. This model has been created for German (de-DE) text.

Model Architecture

This model uses weighted finite-state transducer (WFST) grammars that map strings in spoken form to strings in written form.

Training

The model was constructed using Nemo toolkit as outlined in intro and Text processing

How to Use this Model

To use this model, we can use Riva Skills Quick start guide , it is a starting point to try out Riva models . Information regarding Quick start guide can be found : here.

Input

This model is part of a pipeline for speech to text and accepts text as input.

Output

The output is written form text.
