On-device voice

Loaded only when voice runs on this device.

Natural voice also uses phonemizer 1.2.1 (https://github.com/xenova/phonemizer.js), which embeds eSpeak NG (https://github.com/espeak-ng/espeak-ng, GPL-3.0-or-later). It is not part of this repository or its build: when natural voice first starts, the user's browser downloads the pinned file from cdn.jsdelivr.net/npm/[email protected] and checks its SHA-256 before use. GEV_NATURAL_VOICE=off turns natural voice off.
