Source: https://github.com/espeak-ng/espeak-ng

What it supplies: The README presents eSpeak NG as a small, fast, multilingual formant text-to-speech engine.

Useful for: - Speak text from the command line or write WAV files.
- Use as a phoneme front end for another synthesizer or MBROLA.
- Provide a screen-reader voice through SAPI5.

First action: - Read the user guide for command line and library use.
- Use the building guide to compile it.

Prerequisites and limits: The README platform table lists Linux, BSD, Android 4.0, Windows 8 and Mac.

- Speech is less natural than recorded-voice synthesizers.
- SSML support is not complete.

Source-documented: GPL version 3 or later.

Written from the README text only. Statements are as the README gives them; nothing was installed or run.
Based on intro, features, platforms, documentation and licence README text; other sections were not read in full. Nothing was installed or run and no audio was heard.
