Go back to previous sentence!

This is an innovative audio player specifically designed for language learners who frequently need to replay sentences during their studies. The application, named "Go back to previous sentence!", offers a unique feature where pressing the LEFT ARROW button allows users to repeat the current sentence they are listening to. This functionality is particularly useful when trying to grasp nuances in pronunciation or grammar.

The app analyzes the audio file by reading it and assessing the sound intensity. It splits the audio into distinct sentences based on silent intervals that exceed a certain threshold. These silent sections act as separators between sentences. When you press the LEFT ARROW button, the app will return to these separators, allowing you to navigate through the audio content sentence by sentence.

For instance, if you press the LEFT ARROW button once, you will hear the same sentence again. Pressing it twice will take you back to the previous sentence, and pressing it three times will bring you to the one before that, and so on. This makes it easy to review any part of the audio without having to manually rewind or search for specific parts. Users can also customize the threshold settings for sound intensity and silence duration, tailoring the app to their specific needs.

Moreover, the app supports Bluetooth audio headsets and controllers, enabling seamless operation without the need to look away from your textbook or notes. With this feature, you can control playback using the remote controller alone, making the learning process more efficient and less disruptive.
