help eSpeak NG FAQ
What is eSpeak NG?
eSpeak NG is a compact, open-source speech synthesizer that converts text into spoken audio. It is valued for speed, small size, and broad language support rather than for sounding like a premium neural voice.
Which platforms support eSpeak NG?
eSpeak NG is cross-platform and can be used on Linux, Windows, macOS, and other systems through packages or source builds. It is also commonly integrated into accessibility tools such as screen readers.
Can eSpeak NG be used with NVDA?
Yes. NVDA can use eSpeak NG through the eSpeak NG speech synthesizer add-on or related speech-driver packages, depending on the NVDA version and installation method.
Why does eSpeak NG sound robotic?
Its formant-based synthesis generates speech from linguistic rules rather than a large recorded or neural voice model. That makes it lightweight and fast, but the result is usually less natural than services such as Microsoft Azure Speech or Google Cloud Text-to-Speech.
