sonara-client

Talk to the Sonara text-to-speech runtime from Python 3.9+. Standard library only.

import sonara_client

with sonara_client.connect("my-app", runtime_path=r"C:\path\to\sonarad.exe") as sonara:
    item = sonara.speak("Hello.", label="greeting")
    sonara.set("rate", 240)
    with sonara.subscribe(["state", "items"]) as events:
        for e in events:
            if e["event"] == "item" and e["item_id"] == item and e["phase"] != "started":
                break
  • connect(client_name, *, runtime_path=None, home=None, autostart=True, require=(), extensions=(), keep_alive=False): finds the shared runtime through runtime.json, starts the bundled sonarad.exe when none is usable (runtime_path, default SONARA_RUNTIME), takes over an idle incompatible one.
  • speak(text, mode=None, interrupt=None, label=None) returns the item id; control(action); set(key, value) / get(key); voices(engine=None).
  • subscribe(events) opens an event stream on its own connection: iterate it, or read(timeout).
  • request(type, fields=None, timeout=None) sends any message. Each request waits up to connect(..., timeout=10.0) seconds, engine_test and a provider refresh at least 90 s; no reply in time closes the client. A request over 1 MiB (UTF-8) is refused with E_BAD_REQUEST and the client stays open.
  • channels, agent, system: extension namespaces that send the protocol's extension messages as they are.
  • Errors are SonaraError with a code. The client is thread-safe.

Guide: Bundle Sonara in your app. Tests: python -m pytest clients/python/tests -q (the end-to-end ones need cargo build -p sonarad).

MIT. Ship THIRD_PARTY_NOTICES.md with an app that bundles the runtime.
