How to Control Audio Speed and Lock-Screen Playback

November 12, 2026 · 4 min read

Tailor your listening pace to your day. Learn how to adjust playback speed without pitch distortion and control narration from your phone's lock screen in GemReader.

Why Thoughtful Audio Controls Matter

Listening to a book should fit effortlessly into the rhythm of your day. You might want to accelerate narration while working through dense non-fiction, or slow things down while relaxing into poetry or practicing a new language.

GemReader provides comprehensive playback controls built for everyday comfort. Narration pitch is mathematically preserved across speeds, avoiding the harsh artificial distortion common in basic players, while seamless system notifications let you pause and skip without unlocking your screen.

What You'll Need

To manage audio controls, make sure you have:

• **Platforms**: GemReader installed on your device (Android or iOS). • **Prerequisites**: Active audio playback (either Read Aloud text-to-speech or an attached chapter audio file). • **Hardware**: Any smartphone, tablet, or connected Bluetooth earphones/speaker.

Step-by-Step Instructions

1. While listening to a book or chapter track, locate the floating audio bar at the bottom of the reading view. 2. Tap the playback speed indicator to choose your preferred pace: - Choose a slower rate (such as `0.75x`) for deliberate study or language practice. - Choose `1.0x` for standard conversational cadence. - Choose `1.25x`, `1.5x`, or `2.0x` for efficient information review. 3. Use the forward and backward jump buttons to skip ahead or replay the last few seconds of text. 4. Lock your phone or switch to another app: playback continues smoothly in the background. 5. Control playback directly from your lock screen or notification shade using standard **Play**, **Pause**, and track skip buttons, or use your Bluetooth headset controls.
