iOS SFSpeechRecognizer stops FMOD playing

Unreal Engine
1

Hello,

My team wanted a function speeches to text for chat.
So I implemented an unreal plugin by referring https://github.com/bpolania/Speech-Recognition and https://qiita.com/ryohorie/items/1e3b9cd78be752ae9cdd

But when I initialize function, fmod stops playing.
Until relaunch the game or open and close the iOS Control Center.

Can you help me to keep the sound from stopping?

UE4 already has FIOSPlatformMisc::EnableVoiceChat( bool ) .
This function set [[AVAudioSession sharedInstance] setCategory …] properly.
