English language files for gruut tokenizer/phonemizer
Decision gist · record as of 2026-08-14
No, unless you are maintaining an existing system that depends on this package. The project is archived as of 2024-11-15 with no active maintenance; no security updates or bug fixes will be released. If you need English phonemization or text tokenization, consider actively maintained alternatives. If you already depend on this package for production, it is acceptable only if you can tolerate no upstream support.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Linux and Python 3.7 or higher; this is a data package and must be installed alongside the parent package to function.
- High install friction: this is a language data package with no runtime dependencies, but requires Python 3.7 or higher and Linux.
- The project is archived as of 2024-11-15, meaning no active maintenance or bug fixes are forthcoming.

What it is and what it does
gruut-lang-en is a language data package that supplies English phonetic and linguistic data for text processing and phonemization. It is not a standalone tool but a companion package that provides pre-built language models and phonetic rules. When installed, it enables processing of English text (en-us and en variants) and outputs structured word-level information including IPA phonemes, part-of-speech tags, and break markers for punctuation.
The package handles context-sensitive pronunciation, supports SSML markup for mixed-language input, and can verbalize numbers, dates, currency, and times. However, the project is now archived as of 2024-11-15, meaning no new features or maintenance will occur.
Use it for
- Building text-to-speech systems that require accurate English phoneme sequences for synthesis.
- Processing English text in speech recognition pipelines where phonetic alignment is needed.
- Analyzing or cleaning English text with automatic tokenization and part-of-speech tagging.
- Converting written English including dates, numbers, and currency into spoken form.
- Linguistic research or NLP tasks requiring IPA phoneme output for English words in context.
