## What it is
A Python library and command-line tool that converts words and texts into phonemes across many languages. It wraps multiple backends (espeak-ng, espeak-mbrola, festival, segments) to produce IPA or custom phone-set transcriptions.

## Use cases
- convert text to IPA phonemes in Python
- phonemize text for TTS training data
- get phonetic transcription of words in multiple languages
- grapheme to phoneme conversion for speech datasets
- phonemize text from the command line
- build pronunciation lexicons with espeak

## When to choose
- you need phonetic transcriptions for many languages in Python
- you are preparing text-to-speech or speech recognition training data
- you want both a CLI and a Python API for phonemization

## When to avoid
- you need a pure-Python solution without external espeak/festival dependencies
- you need full TTS synthesis rather than phoneme transcription
- you need very fast phonemization of huge corpora without parallelization

## Facets
- artifact type: library
- maturity: stable

- domain: speech-processing, developer-tools
- platform: python, windows, cli
