Unhandled Google TTS Abort Exception

[zaheerabbas-prodigal]

I am seeing the below exception thrown from Google TTS - observed this when the user goes silent -

raise _create_rpc_error(
grpc.aio._call.AioRpcError: <AioRpcError of RPC that terminated with:
        status = StatusCode.ABORTED
        details = "Stream aborted due to long duration elapsed without input sent. Input must be sent continuously, at least every 5s seconds."
        debug_error_string = "UNKNOWN:Error received from peer ipv4:142.251.222.170:443 {grpc_message:"Stream aborted due to long duration elapsed without input sent. Input must be sent continuously, at least every 5s seconds.", grpc_status:10, created_time:"2025-05-27T11:02:56.881525+05:30"}"
>

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/app/lib/python3.11/site-packages/livekit/plugins/google/tts.py", line 352, in _run_stream
    async for resp in stream:

    raise exceptions.from_grpc_error(rpc_error) from rpc_error
google.api_core.exceptions.Aborted: 409 Stream aborted due to long duration elapsed without input sent. Input must be sent continuously, at least every 5s seconds.
