On Craze, Seed Audio 1.0 generates speech from a script. You can optionally supply audio or image references, but not both types together.
Seed Audio 1.0 accepts references as well as text, giving you another way to guide narration.
Write the line you want spoken. Craze sends that script to the text-to-speech route and returns an audio file.
Upload up to three audio clips, each at most 30 seconds, to guide the generated voice. Alternatively, provide one image reference. You cannot mix audio and image references in one generation.
For different characters, generate lines separately and assemble them in the editor. The Craze route does not expose a multi-speaker assignment control.
Place the generated speech in the editor and adjust its timing against your video there. This route does not expose millisecond-level timing annotations.
Provide your narration script in the language you want to generate. For a localized version, submit a translated script as another generation.
Pricing starts at $0.264 per 1,000 characters and varies with script length. The rate card has no reference-type price axis. The calculator shows the total before you generate.

MiniMax Speech 2.8 HD is text-to-speech with optional voice ID and sound tags. Seed Audio 1.0 also generates speech but accepts audio or image references. Neither Craze route is a complete music-and-foley mixer.
For expressive English narration, Gemini 3.1 Flash TTS offers directorial control. For multilingual narration with emotion tags, Qwen Audio 3.0 TTS is another option. Seed Speech offers text narration with optional voice ID.
Seed Audio 1.0 accepts up to three audio references, each at most 30 seconds, or one image reference. Choose one reference type per request. The route does not expose speaker-to-reference assignments.

Edit the speech track's timing and level alongside separately generated sound in your project.
For foley such as footsteps or a door opening, use a sound-effects model and mix the result with your narration.
For two speakers, generate their lines separately with the appropriate references and arrange the audio in the editor. Craze does not map multiple references to named speakers in one TTS request.
Keep each script within 2,048 characters. Assemble longer exchanges from multiple generated clips.
This Craze route does not expose a timing-annotation control. Adjust the generated speech's position in your edit to match a visual beat.
Write the translated line as the script for each localized generation. An optional reference can guide the voice, but this Craze route does not offer a separate voice-conversion task.
Describe what you want the way you would brief an editor, and Craze writes the Seed Audio 1.0 prompts for you.

Each voiceover lands on the timeline under your cut, and exports with the video or on its own as MP3. Generations come out of your plan's monthly credits, from $0.264 per 1,000 characters, with top-ups when you need more.
