Overview

Status

SpeakSwiftlyServer is actively maintained and supported by Gale.

What This Project Is

SpeakSwiftlyServer (Speak Swiftly) is a high-quality, local-first speech runtime built for macOS. Custom voices, batch jobs, easy integrations, and more.

Motivation

This project was borne of my own need for affordable, customizable, high-quality text-to-speech, with easy integration into the apps I already used. I'm quite proud of this one already, and tbh we're just getting started~

Quick Start

Add or upgrade the Socket marketplace entry to your Codex. Then, restart Codex and enable Speak Swiftly in the Plugin Directory under Socket.

Add Socket:

codex plugin marketplace add gaelic-ghost/socket

Upgrade Socket and Enabled Plugins:

codex plugin marketplace upgrade socket

After the plugin is enabled, install or refresh the local speech service:

xcrun swift run SpeakSwiftlyServerTool launch-agent install
xcrun swift run SpeakSwiftlyServerTool healthcheck

If using Codex Hooks, review and trust the stop hook from Speak Swiftly to have all replies automatically spoken in the order they arrive.

The plugin and the local service are separate on purpose. The plugin gives Codex the skills, MCP connection, and speech hooks. The local service is the native Swift process that actually speaks.

Usage

Once the service is healthy, agents can use Speak Swiftly to:

• speak "final assistant replies" through Speak Swiftly
• queue speech, create new voice profiles, adjust how words are spoken, and control playback
• inspect the runtime, voice profiles, text profiles, and recent requests
• set default voice and model preferences

Operators can also open the local control panel at http://127.0.0.1:7338/control-panel/ when running the foreground tool, or at the configured local HTTP listener port for an installed service.

The normal end-user path is plugin-managed. Do not copy repo-local hook files into a Codex home directory for ordinary setup.

For the detailed HTTP and MCP contract, see [API.md](./API.md).

Development

For local setup, validation, contribution workflow, release workflow, LaunchAgent details, embedding notes, plugin-maintainer guidance, and repo-specific maintainer rules, see [CONTRIBUTING.md](./CONTRIBUTING.md) and [AGENTS.md](./AGENTS.md).
