ovos-utterance-normalizer
ovos-utterance-normalizer is an OVOS plugin that
normalizes utterances before intent parsing. It expands contractions, converts spoken
numbers to digits, strips punctuation, and applies other language-specific cleanup so
that intent parsers get a consistent input.
The plugin also fixes text encoding errors with python-ftfy.
It is enabled by default in mycroft.conf.
Install
pip install ovos-utterance-normalizer
Usage
ovos-utterance-normalizer registers as an
OVOS PHAL opm.transformer.text
plugin, named ovos-utterance-normalizer. ovos-core
loads it automatically when it is installed and enabled in the configuration.
For each utterance, the plugin produces up to three variants: the utterance with contractions expanded, the original utterance, and the normalized utterance. Punctuation is stripped from each variant, and duplicates are removed while keeping the original order.
Supported configuration options, under the plugin name in mycroft.conf:
| Option | Default | Description |
|---|---|---|
lang |
en-us |
Fallback language, used when no language is given in the utterance context |
fix_encoding_errors |
true |
Fix encoding errors with ftfy before normalizing |
strip_punctuation |
true |
Strip punctuation from each output variant |
Normalization is language-specific. English, Portuguese, Ukrainian, Catalan, Czech, Azerbaijani, Russian, and German each have a dedicated normalizer. Other languages fall back to the generic normalizer.
