I think the plugin is not working once you export the project, although it is loaded as showed in the log: “Loaded Plugin OVRLipSync” then, it will not work (not initialized), any fix for this? ---

Any easy way to get the text of any speech without having to match keywords or predefined phrases? Maybe get the I know this can be inaccurate, but perfect sentences is not important for what I need this for. Manager-\>UnknownPhrase\_method(return the whatever phrase); ??? ---

I’m having a problem with a grammar script. ```auto #JSGF V1.0; public = ( | | | | | ) ( | | | | ); = ; = ; = ; = ; = ; = ; = ; = ; = ; = ; = ; = ( roth | mara | corda | ashti | kava | dolo | hana ); = ( vort | para | nama | haku | mado ); = ( chiya | kanto | vanti | bren ); = ( mapa | haya ); = ( juna | toda | wato ); = ( dema | cora | seto ); = ( gen | turb | rata ); ``` Is anyone able to see what’s wrong with that? The words all exist in the dictionary and if I Enable Grammar Mode with the “numbers” script it starts fine. But if I use the script above I get “Speech recognition thread failed to start”. Is there any way to debug this? Edit: fixed it. I’ll share how I debugged it since it’s pretty non-obvious. Even if you’re using grammar mode, switch to keyword mode and feed it all of your new words in a word list. Then comment all of your new words out in the .dict file using a semi-colon ; After that, re-enable them one at a time and hit play. If it “fails to start utterance” then your syllables in the word you just uncommented are wrong. I kept getting caught out by G (should be JH), H (HH) and O (OW). ---

This works amazingly well in 4.18! THANK YOU Wow,. I have read the entire thread before I ask you for help, but: The once thing i cannot figure out how to do is to link an added phrase to a new Function (or Blueprint?)! I can see to add a phrase add a ‘+’ PIN to the ‘Make Array’ and I know there will be a corresponding Function. I already got it to play a Wav file as it does Start Game and nearly passed out when it worked! WOW WOW WOW… any help greatly appreciated! THANK YOU! _ **EDIT: I always find things on my own right after asking, it is the ‘WordsSpoke’ Function 🙂 And as I hoped there is another easy to understand array!** _ Although I still welcome any and all advice about optimizing recognition… Phrases like thank you do not seem to work even though I found ‘thank’, ‘you’ and ‘thankyou’ in the dict file!.. THANK YOU! ---
