About Voice Speed Changer
Sometimes generated speech feels too slow to keep your attention or too fast to follow comfortably. The Voice Speed Changer lets you adjust the pace of your TTS audio, speeding it up or slowing it down until it sounds just right. It's a small tweak that makes a big difference in how easy your audio is to listen to.
Generate or load your speech, set the speed you want, and the audio adjusts accordingly. It works in your browser with no install and no account needed. The tool is free, applies changes instantly, and leaves your audio watermark-free. Your content stays private.
