This results in better participation in conversations. There are several settings to optimize the subtitles, according to your device size and personal preferences. Earfy is optimized for devices (tablet and smartphone) running Android 4. 0 or higher. Combining the Earfy app with the Nuance Swype keyboard, leads to the best results.
