Speaker app

The application is initial step towards Accent detector

Build

The project relies on Oboe library

Mac

make sure that you have $OBOE_PATH set as environment variable

Linux

For some reasons the env var $OBOE_PATH is not detected by CMake To build the project you need to set it explicitly in CMakeLists.txt

Windows

Road map

1. Read & Write audio simultaneously from/to mic and speaker

   • Support earpiece
   • Support USB headphones
   • Support BT headphones
   • Achieve minimal latency

2. Embed tongue twisters

   • UI for selecting twisters
   • UI font and background selection (Themes)

3. Draw FFT in real time

   • Calculate FFT without affecting audio transmitter (multithreading)
   • Display FFT based spectrogram in real time
   • Achieve minimal latency

4. Set timbre preferences

   • Calculate timbre of the speaker
   • Display timbre scale
   • Introduce the ability to set timbre range
   • Vibrate/sound when the speaker gets out of the range

5. Speech to text

   • Use embedded tools for speech recognition
   • Try word to word processing with confidence level
   • Colorize text based on confidence level
