Dengjen Neural Voices for NVDA

This add-on adds neural text-to-speech voices to NVDA. It provides a synthesizer driver for Piper voice models, which run entirely on your own machine, plus a voice manager for downloading and installing voices. An internet connection is needed to download voices, but not to speak with them.

Piper is a fast, local neural text-to-speech system that sounds great and is optimized for low-end devices such as the Raspberry Pi. You can hear what the voices sound like on the Piper voice samples page. Speech is generated by dengjen, a cross-platform Rust engine for neural TTS models.
