I know that you cannot play music to your phone call without hacking the code as discussed here but I would like to connect an audio generator to a phone call. This approach should be simpler because I have the synthesizer code myself. Assume the code can be run in real-time with only a little tau time-lag so fits very well in such an application. I am not sure how you can reach an real-time access from your keyboard to your phone call.
Cases where the feature is needed
- Sometimes, I am in a library where I cannot talk and I cannot move without disturbing my work. However, I could easily type to the caller such that the text would be converted to speech in real-time.
- Person with a disability that he cannot speak but only type. People are calling him, but currently, he cannot provide discussions because of restrictions and little understanding about the tech.
I am using Samsung Galaxy S4 GT-i9506 with CyanogenMod 13 (Android 6.0). So I want
- Type with your Laptop or Bluetooth keyboard connected to your phone.
- Synthesize the typed text in real time to the phone conversation.
