Short summary
The Convai character is unable to detect voice input
What happened?
I followed one of the more recent Convai tutorials titled Real-Time AI Conversations & Facial Animation for MetaHumans to set up a Convai character in the sample FirstPerson project.
Once I finished setting everything up, I tested the voice interaction via Push To Talk, and nothing happened. I also tested the feature where you type to communicate with the Chatbot, and it did respond to that.
I checked, and I selected the proper input. Also, the Unreal Engine Editor is has allowed microphone access.
I have another project in UE5.7 with the Convai-3.6.9-hotfix-2 version, and the chatbot is responsive there, with the same microphone.
One thing I also noticed in the new version was that the Test button for the Mic is not visible in the Settings Widget, which I technically fixed by setting the Size box (where TestMicRecord_btn_1 is located) to be Visible. But now when I test any mic, I get the warnings:
ConvaiPlayerLog: Warning: StartRecording: already talking!
ConvaiPlayerLog: Warning: FinishRecording: did not start recording
On my other Convai version it returns that it recorded for a certain number of seconds.
I didn’t change the BPs much, I only added some prints to check whether the Start Talking and Finish Talking get triggered, and whether the Muted variable is indeed toggled.
Also, I do make sure that I release the T key a few seconds after I am finished talking.
