About Voice Speed Changer

About the Voice Speed Changer

The Voice Speed Changer speeds up or slows down a spoken recording — tighten a voice-over to fit a slot, or slow one down to transcribe or study it. It is tuned for speech.

Modest changes stay natural; to change pitch instead of speed, use the Voice Pitch Changer.

Frequently Asked Questions

Will speeding up change the pitch?

Depending on the mode, speeding up can raise pitch. Use a time-stretch option to keep the original pitch, or the Pitch Changer to compensate.

How much can I change the speed?

Up to ~10–20% stays natural for speech; beyond that it sounds noticeably processed.
