14.8 Compatibility Speech Servers ¶

These retained direct servers support existing installations, not the recommended first setup or platform matrix:

espeak: Direct Linux Tcl server. make espeak needs Tclx at runtime, Tcl 8.6 headers, eSpeak NG development libraries, and C++. Useful for compatibility testing; new installations should use Omnivox.
swiftmac: Direct Swift macOS server, needing Swift 5.9 or newer and make swiftmac. See servers/mac-swiftmac/Readme.org for this alternative to Omnivox’s AVSpeechSynthesizer engine.
mac: Legacy Python/PyObjC server. The unset Darwin selector still names it as a compatibility default, not an initial-user route. It needs Foundation, AppKit, and PyObjCTools.
outloud: Direct Linux IBM TTS/Eloquence adapter with separately licensed compatible runtime. Emacsvox does not distribute it. Voxin availability is described at https://voxin.oralux.net.
dtk-soft: Direct Software DECtalk adapter with separately installed runtime. See servers/software-dtk/Readme.org. Licensed runtimes are not distributed by Emacsvox.

The native Windows audio, standalone Eloquence, and standalone DECtalk bridges under servers/ are advanced WSL compatibility paths. Piper is an optional Omnivox engine/model workflow, not a primary Emacsvox server.
