The Science of Audiobook Acceleration
Most professional voice narrators speak at roughly 130 to 150 words per minute to ensure maximum articulation and emotional resonance. However, human auditory processing is capable of comprehending conversational speech up to 275 to 300 words per minute without substantial loss in retention.
Listening at 1.25x to 1.5x speed is widely regarded as the cognitive "sweet spot": it tightens conversational pauses and trims 33% off your listening time while preserving the voice actor's emotional timber.
