Real time subtitle for react native app, its possible? - react-native

I'm trying to implement automatic subtitle generation in a React native app and I thought about a subtitle approach via streaming.
Calling some Google speech service, azure, etc ... and translating in real time that the video is playing
But I'm a little lost on how to do this with react native, could you help me?
Does anyone have any ideas or a lib not free that would solve this problem of automatic subtitle generation?
Have you been through this?

React native ScrollView effect like youtube's one

I'm trying to get an effect like youtube's one in the ScrollView of my react native app.
I don't really know how to search for this, so if anyone knows of a package or a video tutorial that could help me, I would really appreciate it.
That's a short video showing the effect I've said, but I believe it is present in all Youtube apps.
Basically, it shows you the header when you drag it up from anywhere on the screen.

React Native record video and capture Speech to Text

I'm using React Native Camera to record video. I would also like to transcribe the voice at the same time (speech-to-text). I'm looking at React Native Voice but I don't think I can use both libraries at once (sharing the Mic input).
Wondering if anyone has ideas besides uploading the final video file somewhere to get transcribed.
Yes, you can.
You can record video with React Native Camera, and using speech-to-text in Voice Library.
For voice library you can see this or this guides.

React Native bridge (interaction from react to iOS)

I'm currently learning React Native and I've created a small app where I can send events from my Objective-C code to the React side of things.
I'm struggling to understand how to asynchronously send events from React to a listener on the ObjectiveC side.
I feel I've probably misunderstood a critical part about the Bridging as I'm struggling to search for the correct thing (if it even exists). Could someone please pointe in the right direction or if this is even feasible.
Managed to find the answer. I was searching for the wrong thing (newbie mistake). Here is a link that helped me: https://facebook.github.io/react-native/docs/native-modules-ios.html
