Voice Notify
APK
Announces status bar notification messages using Text-To-Speech (TTS), allowing you to know what a notification says without looking at the screen. * Customizable TTS message * Ignore specific apps or notifications containing defined text * Choice of TTS audio stream (see Google Play descriptions for more details) * Choice of speaking when screen or headset is on or off, or while silent/vibrate * Quiet Time * Shake-to-silence * Custom delay of TTS after notification For technical reasons, VN operates through Android's Accessibility service and must be enabled in the Accessibility settings. The Accessibility service will give a warning that VN may be able to collect personal data. This is because Accessibility doesn't know what or how data passing through it is used by enabled apps. VN only uses Accessibility to read notification text which is passed directly to TTS and temporary memory (for the notification log). The TTS service (outside the control of VN) may also print spoken text in the logcat.
