Hi everyone, I’m experiencing an issue with Voice Notification and TTS voices on my Ignition Gateway. ### Environment - Ignition Gateway: 8.3.6 (b2026042713) - Voice Notification Module: 7.3.6 (b2026042713) - TTS Voice Module: en\_us\_katherine 6.3.0 (b2024112210) - OS / Runtime: - Docker container (Linux, x86\_64) - Windows 11 installation - The issue occurs in both environments with identical behavior. ### At Gateway startup, I get the following error: ```python java.lang.Exception: Failed to initialize voice 'katherine' from 'C:\Program Files\Inductive Automation\Ignition\temp\cere\voices\cerevoice_katherine_6.0.0_48k.voice'. Error code: 0 at com.inductiveautomation.services.tts.cere.CereEngine$CereVoice.init(CereEngine.java:251) at com.inductiveautomation.services.tts.cere.CereEngine.registerVoice(CereEngine.java:77) at com.inductiveautomation.services.tts.cere.CereSystem.registerVoice(CereSystem.java:271) at com.inductiveautomation.services.tts.cere.VoiceModuleHook.serviceReady(VoiceModuleHook.java:96) at com.inductiveautomation.ignition.gateway.services.ModuleServicesManagerImpl.subscribe(ModuleServicesManagerImpl.java:93) at com.inductiveautomation.services.tts.cere.VoiceModuleHook.startup(VoiceModuleHook.java:83) at com.inductiveautomation.ignition.gateway.modules.ModuleInstance.startup(ModuleInstance.java:755) at com.inductiveautomation.ignition.gateway.modules.ModuleManagerImpl.runStartupPhase(ModuleManagerImpl.java:539) at com.inductiveautomation.ignition.gateway.modules.ModuleManagerImpl.startup(ModuleManagerImpl.java:478) at com.inductiveautomation.ignition.gateway.IgnitionGateway.startupInternal(IgnitionGateway.java:1385) at com.inductiveautomation.ignition.gateway.redundancy.RedundancyManagerImpl.startup(RedundancyManagerImpl.java:367) at com.inductiveautomation.ignition.gateway.IgnitionGateway.initRedundancy(IgnitionGateway.java:807) at com.inductiveautomation.ignition.gateway.IgnitionGateway.lambda$initInternal$1(IgnitionGateway.java:720) at com.inductiveautomation.ignition.common.execution.impl.BasicExecutionEngine$ThrowableCatchingRunnable.run(BasicExecutionEngine.java:557) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.run(Unknown Source) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source) ``` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/5/859f495c730a6bf5009cd2569c841b3f2cf2dee3.png) For sure I'm missing something, any suggestions would be appreciated.

We're in the process of fixing this, but it's going to take some time to get a renewed license from our voice provider. We'll keep this thread updated as to when a fix becomes available, however I'd recommend anyone relying on voice notifications in 8.3 temporarily move to a different form of notification (sms, email, etc.) until we're able to get the underlying license updated. ---

Hi, Thank you for the feedback. Could you please keep me updated if there are any developments?I will soon need to install the VoIP module at a client’s site, and I will have to proceed using version 8.3. Thanks in advance. ---
