Write or paste the script — Up to 10,000 characters per clip on MiniMax and Multilingual v2; split a long video into scenes. 2. Pick a voice that fits the video — A clear explainer voice for tutorials, a smooth read for ads, a deep voice for trailers; preview before you generate. 3. Set pace and tone — About 0.9–1.0× speed for courses, 1.1× for ads; emotion on MiniMax, audio tags like [excited] on Eleven v3. 4. Generate, download and place it — Download MP3, WAV or FLAC with no watermark and drop it on your video timeline. ## In depth ### What a voice-over is A voice-over is a voice heard over the picture by someone who isn't speaking on screen — the narrator of a documentary, the announcer in an ad, the guide in a tutorial [1]. An AI voice-over replaces the recording session with a script and a synthetic voice, so every revision is a regeneration rather than a re-record. ### Writing a script for voice-over Scripts read aloud differ from scripts read on a page: - Short sentences — one idea each, so the voice can breathe. - Spoken numbers — “twenty-five percent”, not “25%”, when the reading matters. - Pace for the picture — conversational speech runs roughly 130–150 words per minute, so time the script against the edit [2]. - Signposts — “first”, “next”, “finally” help viewers follow along. ### Matching the voice to the video A quick map of the demo voices: - Explainers & training — Explanatory Man (MiniMax Speech 2.8 HD). - Ads — Magnetic-Voiced Man (MiniMax Speech 2.8 HD). - Trailers — Movie Trailer (MiniMax Speech 2.8 HD). - Documentary — Brian (ElevenLabs Multilingual v2). - Social hooks — Social Media Host (MiniMax Speech 2.8 HD).

A: There is no single best voice for every video; it depends on the job. In Kenerate AI, MiniMax Speech 2.8 HD is the default for natural reads with emotion control, ElevenLabs Multilingual v2 stays steady over long narration, and Eleven v3 is the most expressive with audio tags. Generate the same line on two or three and keep the one that fits. Q: Is the AI voice over generator free to try? A: Yes, you can start free. A new Kenerate account comes with starter credits, enough to try several voices on your own script, and every clip downloads without a watermark. When you need more, one-time credit packs top you up, and credits never expire. Q: How long can an AI voice over be? A: Each clip can be up to 10,000 characters on MiniMax and ElevenLabs Multilingual v2, and up to 5,000 on Eleven v3 and Qwen3. For a longer video, split the script by scene, generate each clip with the same voice and settings, and join them in your editor. The speech time calculator shows how long a script runs. Q: Can I use an AI voiceover on YouTube? A: Yes, many creators use AI voiceovers for YouTube explainers, tutorials and faceless channels. Download the clip, place it under your visuals and keep one voice across uploads so the channel sounds consistent. Check YouTube's current rules on labelling synthetic content, and only clone a voice you have permission to use. Q: Can I make a voice over in another language? A: Yes. Paste a translated script and pick a voice that speaks that language: MiniMax voices cover 40 languages, ElevenLabs Multilingual v2 covers 29 and Eleven v3 covers 70. If the video is already recorded in one language, the AI video translator and dubbing tool can translate the speech for you. Q: Can I use my own voice for a voice over? A: Yes. Upload a clean 3–15 second sample and Qwen3 Voice Clone reads your script in that voice straight away, with no training step. You can also describe a brand-new voice in words with Voice Design. Only clone your own voice or one you have clear permission to use — never clone someone without their consent. Q: What is the difference between an AI voice over and text to speech? A: They use the same technology. Text to speech is the general tool that reads any text aloud; an AI voice over is speech made for a video, ad or course, where pacing, tone and timing against the picture matter most. This page focuses on voice-over work; the text to speech page covers everyday reading and accessibility. ## Related pages - Text to Speech: https://kenerateai.com/text-to-speech - YouTube Shorts Voice Generator: https://kenerateai.com/youtube-shorts-voice-generator - PowerPoint Voice-Over: https://kenerateai.com/powerpoint-voice-over - Speech Time Calculator: https://kenerateai.com/speech-time-calculator ## Sources - Kenerate Voice Studio (engines, voices and limits from the app's code): https://kenerateai.com/app/voice - MiniMax Speech 2.8 HD on WaveSpeed: https://wavespeed.ai/models/minimax/speech-2.8-hd - ElevenLabs Eleven v3 on WaveSpeed: https://wavespeed.ai/models/elevenlabs/eleven-v3 - ElevenLabs — text to speech documentation: https://elevenlabs.io/docs/overview/capabilities/text-to-speech - ElevenLabs — Eleven v3 audio tags: https://elevenlabs.io/blog/v3-audiotags - Qwen3 TTS Voice Clone on WaveSpeed: https://wavespeed.ai/models/wavespeed-ai/qwen3-tts/voice-clone - Qwen3 TTS Voice Design on WaveSpeed: https://wavespeed.ai/models/wavespeed-ai/qwen3-tts/voice-design
