Does it support do tts in parallel?

[wj21067855]

I want to transcribe text in audio in parallel, so I want to deploy this vibe voice in fastAPI, and expose an api which call from FE (react), I want to know does this tts model support do it in parallel?

Why I ask for this, as in the sample code,

@app.websocket("/stream")
async def websocket_stream(ws: WebSocket) -> None:
    await ws.accept()
    text = ws.query_params.get("text", "")
    print(f"Client connected, text={text!r}")
    cfg_param = ws.query_params.get("cfg")
    steps_param = ws.query_params.get("steps")
    voice_param = ws.query_params.get("voice")

    try:
        cfg_scale = float(cfg_param) if cfg_param is not None else 1.5
    except ValueError:
        cfg_scale = 1.5
    if cfg_scale <= 0:
        cfg_scale = 1.5
    try:
        inference_steps = int(steps_param) if steps_param is not None else None
        if inference_steps is not None and inference_steps <= 0:
            inference_steps = None
    except ValueError:
        inference_steps = None

    service: StreamingTTSService = app.state.tts_service
    lock: asyncio.Lock = app.state.websocket_lock

    if lock.locked():
        busy_message = {
            "type": "log",
            "event": "backend_busy",
            "data": {"message": "Please wait for the other requests to complete."},
            "timestamp": get_timestamp(),
        }
        print("Please wait for the other requests to complete.")
        try:
            await ws.send_text(json.dumps(busy_message))
        except Exception:
            pass
        await ws.close(code=1013, reason="Service busy")
        return

    acquired = False

it only support the task tts one by one.
