Speaki - Voice Notifications is an Android application developed by Shahar David that reads your notifications aloud using the Text-to-Speech (TTS) feature of your device. You can choose which apps you want Speaki to read aloud, and it will try to learn and read only relevant text from your notifications. You can also protect your privacy by controlling when Speaki should read aloud using the Speak Output feature.

Additionally, the app offers a Silent Hours feature and a Caller ID feature that speaks the caller's name when you receive a call (for Android 8.1 and below). You can stop Speaki from reading by shaking your device, double pressing the power key, or pressing the stop/play button on your headset. The app also has a quick enable/disable switch and tile.

It's worth noting that Speaki can only read your notifications if your device's TTS supports the language of the notification text. You can use the default TTS engine or any other TTS engine you find and download from the Google Play store. The app supports multiple languages, including English, Spanish, French, German, and more.

Overall, Speaki - Voice Notifications is a useful app for those who want to stay updated with their notifications without having to look at their phone constantly. You are also welcome to request new features or report any bugs you encounter.
