Anime Lip Sync AI: Give Your Character a Voice From an MP3

Making your character talk

1. 1

   Prepare a clean face image

   Front-facing or a slight three-quarter view, the mouth fully visible and closed or slightly open, head and shoulders filling most of the frame. Keep hair, hands and props clear of the mouth. Accepted: JPEG, PNG, GIF and WebP files of 50 MB or less.

2. 2

   Trim the audio

   MP3 only, up to 60 seconds and 25 MB. Billing counts seconds of audio, rounded up, so cut the silence at both ends; anything shorter than 5 seconds is billed as 5.

3. 3

   Pick Standard or Pro, keep the prompt short

   Standard renders 480p at 10 credits a second, Pro 720p at 18. The prompt is optional, and the model’s documentation recommends short prompts in English, so try something like “calm smile, small nods, soft studio light”.

4. 4

   Test 5 seconds, then go long

   Run a 5-second line on Standard and watch the mouth closely. If it tracks, render the full take; if not, try a different face image before spending more. The price shows before you start, failed runs are refunded, and Reuse Input keeps the same image and audio for another go.

Two quality levels, and an alternative

• Spicy Lip Sync Standard

  480p at 10 credits a second. Use it for every test, and for clips you plan to upscale afterwards.

• Spicy Lip Sync Pro

  720p at 18 credits a second, for the final take once a Standard test has shown that your character’s face works.

• Seedance 2.5 (Video Lab)

  No recording yet? Seedance 2.5 animates a character with sound switched on by default, in clips of up to 30 seconds. If the lines are already recorded, Lip Sync is the tool that fits the mouth to them.

Prices for every model are on AI Models.

Faces that give lip sync the best chance

• Front-facing or a slight three-quarter turn. Profiles, and faces tilted far up or down, leave the model less mouth to work with.
• A mouth that is actually drawn: lips or a clear mouth shape, closed or slightly open. A single short stroke, or no mouth at all, leaves little to animate.
• Nothing over the mouth: no hand, fan, mask, cup or strand of hair crossing it.
• A large face in the frame. Crop to head and shoulders instead of sending a full-body sheet.
• Your own original character, or a face you have permission to use. Characters from someone else’s franchise are not yours to put words into.

What it costs

You pay for the length of the audio, rounded up to the next second, with 5 seconds as the minimum.

• 5 seconds: 50 credits on Standard, 90 on Pro.
• 30 seconds: 300 on Standard, 540 on Pro.
• 60 seconds: 600 on Standard, 1,080 on Pro.
• During the beta a new account gets 50 free credits, enough for the 5-second Standard test run this guide suggests (50 credits). More credits come with the plans on Pricing once payments open.

Whose voice it is

Use a voice you have the rights to: your own, a voice actor who has agreed to this use, or text-to-speech whose licence allows it. Do not imitate a real person’s voice without their consent, and do not make a real person appear to say anything. A face and a voice that are yours, fictional or licensed keep you within the Terms.

Pairing it with other tools

• Lip Sync starts from a still image, so it cannot re-voice a clip made in Character Swap. Make the talking shot here and the movement shot there, then cut them together in your editor.
• Standard comes out at 480p. If your clip runs 3 to 15 seconds, Video Upscale can take it to 1080p for 16 credits.
• Need a better face image first? Make or tidy one in the Image Lab on a plain background, with the mouth clearly drawn.
