Motion2DAnimation with a voiceover that sounds like a person
An animation with a voiceover is a cartoon narrated by a voice that tells the story. Bad text to speech ruins a good animation in the first sentence, so Motion2D uses natural neural voices, then times the scenes and captions to the narration rather than the other way round.
Timed to the voice, not stuck on top
When you add an AI voiceover to a finished video, the voice has to fit the picture, so it gets rushed or padded. Motion2D does it in the other order: narration first, then each scene is cut to the length of what is being said.
That is why characters gesture on the right word and captions never fall behind.
- Male and female voices in 11 languages
- Word-level timing for captions
- Background music mixed under the voice, or off
Or use your own voice
Record a short sample and the narration is spoken in your voice instead. It is useful for channels where the voice is the brand. See animate in your own voice.
Example: same script, two voices
Take a 45-second Short on why octopuses have three hearts. With a bright female voice and fast pacing, it suits a science Shorts channel. With a slow, warm male voice, the same words suit a relaxing nature channel. Because scenes are cut to the narration, the slower voice simply gives you longer scenes; nothing gets squeezed.
The Short uses 2 credits, since it's over 20 seconds. Want the voice to be yours? See narrate in your own voice.
Choosing a voice that fits the channel
Match the voice to the promise of the video. A calm, lower voice suits history, documentaries and bedtime stories. A brighter, quicker voice suits Shorts, quizzes and kids' science. For teaching, choose clarity over character: a voice that pronounces every word clearly beats a dramatic one.
Keep one voice per channel. Viewers come back for a voice they recognise. If you publish in several languages, use the same style of voice in each; see supported languages.
- Documentary and history: calm, measured
- Shorts and quizzes: bright, quick
- Lessons: clear above all
- Stories for children: warm and slow
