Sovereign Voice 0.5.2 — on-device voice synthesis with Qwen3-TTS + MLX on Apple Silicon

Description and use

Sovereign Voice 0.5.2 is a macOS app that performs on‑device text‑to‑speech using Qwen3‑TTS and MLX, offering offline, private, and cost‑effective voice synthesis.

Problem

Users of cloud voice services face high per-character costs and lack of offline control.

Outcome

Sovereign Voice delivers offline, private, and cost‑effective voice synthesis on macOS, with a free tier that supports up to 25 generations and a one‑time $19 upgrade for unlimited use.

Workflow

• Download and install the signed DMG from the official landing page.
• Launch the app; the first run downloads ~1.9 GB model weights to disk.
• Use the menu bar daemon or studio window to input text and generate speech.
• Optionally clone a voice from a short audio sample.
• Generate up to 25 free voice outputs; beyond that, continue using the free tier without a paywall.
• Upgrade to the Pro tier ($19) for unlimited generations, custom clones, studio mode, and long‑form synthesis.
