react-native-google-cloud-speech-to-text

Google cloud speech to text streaming GRPC module

* Enable the Speech API
* Record voice as audio file(coming soon!)

Requirements

- React Native >= 0.60
- If you have not already done so,
enable the Google Speech API for your project. You

Adjust the color in a way that looks standard on each platform. On
iOS, the color prop controls the color of the text. On Android, the
color adjusts the background color of the button.
