eSpeak NG is a compact open-source text-to-speech synthesizer supporting over 100 languages and accents, using formant synthesis for small size and high-speed speech. It is available as a command-line tool, a shared library, and a SAPI5 version for Windows screen readers.

Use cases

• convert text to spoken audio from the command line
• add text-to-speech to an accessibility screen reader
• generate WAV files of spoken text in many languages
• embed a lightweight TTS engine in an Android app
• use TTS as a front-end for MBROLA voices
• translate text into phoneme codes for another synthesis engine

When to choose

• you need a tiny, fast TTS engine covering 100+ languages
• you need offline speech synthesis with no cloud dependency
• you want a library or CLI that integrates easily into other programs
• you need SSML/HTML text input support

When to avoid

• you need natural, human-quality voices rather than robotic formant speech
• you need neural TTS quality for consumer-facing products
• you need complete SSML support
