HeyGen 专业语音克隆：30分钟至2小时音频训练
Voice cloning has moved past matching timbre. Most of the work now is in what happens between the words.
HeyGen 的 Professional Voice Clone 用 30 分钟到 2 小时的录音音频训练，保留呼吸、停顿、笑声、口音和元音发音。作者认为这一数据量是关键：短参考片段无法体现长句前的呼吸节奏或语速加快时的口音特征，而这些细微不规则正是听者判断声音是否属于真人的依据。HeyGen 称克隆结果无人能分辨出与你本人的区别。

正文
Voice cloning has moved past matching timbre. Most of the work now is in what happens between the words.
@HeyGen 's Professional Voice Clone trains on 30 minutes to 2 hours of your recorded audio and is built to keep breaths, pauses, laughs, and accent, along with how your vowels sound.
That data range is the point. Two hours of someone talking contains hundreds of hesitations, recoveries, half-laughs, and changes in pace. A short reference clip can’t show a model how you breathe before a long sentence or where your accent comes through when you speed up.
Those small irregularities are what listeners use to decide whether a voice belongs to a person.
HeyGen says the result is a voice no one can tell apart from yours.
