If you do not wish to read too many words, below is the example LUA script for OBS (v27+, Windows OS only) with the media file included (the "replay saved!" phrase, EN voice synthesized, was free at the time of sampling, probably no longer exist because of moderate quality of the artificial model, the sound was heavily modified).

As for the mentioned problem - unlikely developers may fix something like this. There is no details of how to reproduce the problem. What should be installed (3rd party plugins and tools, versions before and after upgrades), how it should be configured and what steps should be taken? Is there any details in the OBS log about the problem?
