# Ai Avatar > MultiTalk model generates a multi-person conversation video from an image and text inputs. Converts text to speech for each person, generating a realistic conversation scene. ## Overview - **Endpoint**: `https://fal.run/fal-ai/ai-avatar/multi-text` - **Model ID**: `fal-ai/ai-avatar/multi-text` - **Category**: image-to-video - **Kind**: inference **Tags**: stylized, transform ## Pricing - **Price**: $0.2 per seconds For more details, see [fal.ai pricing](https://fal.ai/pricing). ## API Information This model can be used via our HTTP API or more conveniently via our client libraries. See the input and output schema below, as well as the usage examples. ### Input Schema The API accepts the following input parameters: - **`image_url`** (`string`, _required_): URL of the input image.

I think it is something called milky pie." - **`voice1`** (`Voice1Enum`, _optional_): The first person's voice to use for speech generation Default value: `"Sarah"` - Default: `"Sarah"` - Options: `"Aria"`, `"Roger"`, `"Sarah"`, `"Laura"`, `"Charlie"`, `"George"`, `"Callum"`, `"River"`, `"Liam"`, `"Charlotte"`, `"Alice"`, `"Matilda"`, `"Will"`, `"Jessica"`, `"Eric"`, `"Chris"`, `"Brian"`, `"Daniel"`, `"Lily"`, `"Bill"` - **`voice2`** (`Voice2Enum`, _optional_): The second person's voice to use for speech generation Default value: `"Roger"` - Default: `"Roger"` - Options: `"Aria"`, `"Roger"`, `"Sarah"`, `"Laura"`, `"Charlie"`, `"George"`, `"Callum"`, `"River"`, `"Liam"`, `"Charlotte"`, `"Alice"`, `"Matilda"`, `"Will"`, `"Jessica"`, `"Eric"`, `"Chris"`, `"Brian"`, `"Daniel"`, `"Lily"`, `"Bill"` - **`prompt`** (`string`, _required_): The text prompt to guide video generation. - Examples: "Two kids talking on a lunch." - **`num_frames`** (`integer`, _optional_): Number of frames to generate. Must be between 81 to 129 (inclusive). If the number of frames is greater than 81, the video will be generated with 1.25x more billing units. Default value: `191` - Default: `191` - Range: `41` to `241` - **`resolution`** (`ResolutionEnum`, _optional_): Resolution of the video to generate. Must be either 480p or 720p. Default value: `"480p"` - Default: `"480p"` - Options: `"480p"`, `"720p"` - **`seed`** (`integer`, _optional_): Random seed for reproducibility. If None, a random seed is chosen. Default value: `81` - Default: `81` - **`acceleration`** (`AccelerationEnum`, _optional_): The acceleration level to use for generation. Default value: `"regular"` - Default: `"regular"` - Options: `"none"`, `"regular"`, `"high"` **Required Parameters Example**: ```json { "image_url": "https://v3.fal.media/files/koala/vhkIF86hmgNTBll_lF1xI_3c7476642b19435aa763fe3b49cf99c7.png", "first_text_input": "Do you know what are we eating?", "second_text_input": "I dont know I am eating this because our mother gave it to us.

I think it is something called milky pie.", "prompt": "Two kids talking on a lunch." }, with_logs=True, on_queue_update=on_queue_update, ) print(result) ``` ### JavaScript Ensure you have the JavaScript client installed: ```bash npm install --save @fal-ai/client ``` Then use the API client to make requests: ```javascript import { fal } from "@fal-ai/client"; const result = await fal.subscribe("fal-ai/ai-avatar/multi-text", { input: { image_url: "https://v3.fal.media/files/koala/vhkIF86hmgNTBll_lF1xI_3c7476642b19435aa763fe3b49cf99c7.png", first_text_input: "Do you know what are we eating?", second_text_input: "I dont know I am eating this because our mother gave it to us. I think it is something called milky pie.", prompt: "Two kids talking on a lunch." }, logs: true, onQueueUpdate: (update) => { if (update.status === "IN_PROGRESS") { update.logs.map((log) => log.message).forEach(console.log); } }, }); console.log(result.data); console.log(result.requestId); ``` ## Additional Resources ### Documentation - [Model Playground](https://fal.ai/models/fal-ai/ai-avatar/multi-text) - [API Documentation](https://fal.ai/models/fal-ai/ai-avatar/multi-text/api) - [OpenAPI Schema](https://fal.ai/api/openapi/queue/openapi.json?endpoint_id=fal-ai/ai-avatar/multi-text) ### fal.ai Platform - [Platform Documentation](https://docs.fal.ai) - [Python Client](https://docs.fal.ai/clients/python) - [JavaScript Client](https://docs.fal.ai/clients/javascript)
