kling-custom-voiceKling Custom Voice creates a reusable custom voice from an audio sample — upload 5–30 seconds of clean, single-speaker audio (.mp3/.wav/.mp4/.mov) or reference a historical video ID. The resulting voice can be used in Kling TTS and the Kling Lip-Sync models, so a digital human or narration can speak in your proprietary voice and then be lip-synced to video.
