## What it is
pyttsx3 is an offline text-to-speech synthesis library for Python 3 that wraps system TTS engines like Sapi5, NSSpeechSynthesizer, and espeak. It provides a simple API to convert text to spoken audio with control over voice, rate, and volume, and can save output to a file.

## Use cases
- convert text to speech offline in python
- make my python script read text aloud
- save synthesized speech to an audio file
- change voice, rate, and volume for tts in python
- add voice output to an accessibility app
- text to speech without internet connection

## When to choose
- you need TTS that works fully offline with no API calls
- you want a simple, cross-platform Python TTS wrapper around system voices
- you need to tweak voice, rate, volume, or save speech to a file

## When to avoid
- you need high-quality neural voices rather than system TTS engines
- you want cloud TTS with many languages and natural voices
- you need streaming or low-latency synthesis in production services

## Facets
- artifact type: library
- maturity: active
- function: tts, audio-processing
- domain: speech-processing, cross-platform
- platform: python, cross-platform, windows
- tags: text-to-speech, offline-tts, speech-synthesis, espeak, sapi5, accessibility, natural-language-processing, macos, linux
