Unstable speech

[Emil-18]

The speech randomly stops and the following error is written to the log ERROR - external:synthDrivers.piper_neural_voices.process_speech_sequence (14:37:55.572) - piper4nvda_asyncio (18500): Failed to execute speech task <synthDrivers.piper_neural_voices.SpeechTask object at 0x00FB5850> Traceback (most recent call last): File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices_init.py", line 132, in process_speech_sequence await callable() File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices_init.py", line 104, in call async for wave_samples in stream: File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices\tts_system.py", line 186, in synthesize async for ret in stream: File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices\grpc_client_init_.py", line 148, in speak yield ret File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices\lib\grpclib\client.py", line 573, in aexit raise exc_val File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices\lib\grpclib\client.py", line 563, in aexit await self._maybe_finish() File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices\lib\grpclib\client.py", line 533, in _maybe_finish await self.recv_trailing_metadata() File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices\lib\grpclib\client.py", line 497, in recv_trailing_metadata self._raise_for_grpc_status(status, message, details) File "C:\Users\e-hes\AppData\Roaming\nvda\addons\piper_neural_voices\synthDrivers\piper_neural_voices\lib\grpclib\client.py", line 356, in _raise_for_grpc_status raise GRPCError(status, message, details) grpclib.exceptions.GRPCError: (<Status.UNKNOWN: 2>, 'Failed to obtain results', None)

This may happen in the middle of a speech sequence. When it happens, It wil omit the text that it happens on. For example if it happens on the letter D when spelling NVDA with one of the spelling commands it will say N, V, A. If it happens at the end, it will most likely speak the next speech sequence sent to it, if not this error happens on that too.
