Good to know

• Speech streams: long texts start playing in about a second while the rest is still being synthesized — no waiting, no length limit.
• The first call starts a small background service that keeps the model warm — repeat calls speak in under a second. It shuts itself down after 15 idle minutes; speak --stop ends it manually.
• Auto-detection recognizes Arabic, Japanese, Korean, Russian, Greek, and Hindi by their alphabets; other Latin-script languages need a hint, e.g. --lang fr.
