Understand this story
HeyGen has launched Professional Voice Clone, which is trained using 30 minutes to 2 hours of recorded audio. Related reports point out that this amount of data is key: short reference clips cannot capture the breathing rhythm before a long sentence or the accent features when speech speeds up, and these subtle irregularities are exactly what listeners use to judge whether a voice belongs to a real person. The reports also say that the clone preserves breathing, pauses, laughter, accent, and vowel pronunciation; HeyGen states that no one can tell the clone's result apart from the person themselves. Currently, this fact is supported only by this one report, with no subsequent developments.

HeyGen Professional Voice Clone: Trained on 30 Minutes to 2 Hours of Audio
HeyGen's Professional Voice Clone is trained on 30 minutes to 2 hours of recorded audio, preserving breaths, pauses, laughter, accents, and vowel pronunciation. The author believes this amount of data is key: short reference clips cannot capture the rhythm of a breath before a long sentence or the accent features that emerge when speech speeds up, and these subtle irregularities are exactly what listeners use to judge whether a voice belongs to a real person. HeyGen claims no one can tell the clone apart from you.
