AI voice generators and video generators are the new must-have for businesses that need quick solutions for marketing content, internal training videos, product demo voiceovers, and more. 

You just can’t scale without the help of generative AI. That’s why 76% of companies use it or at least are starting to explore it. 

One example of an AI voice generator on the market? D-ID—a software that creates digital AI avatars and customized videos with multiple languages to choose from. In this D-ID API review, we’ll cover D-ID’s API features and how you can integrate them with your software, pros and cons, and alternatives to consider on your hunt for AI voice generation software. 

What is D-ID?

D-ID is a generative AI software that creates video content and digital human avatars that businesses can use for customer support, learning and development, and sales video products. 

Its Creative RealityTM Studio uses deep-learning face animation technology and language learning models to generate AI portraits inspired by the platform’s existing library of faces or your own image. Then, you can make your AI portrait speak in a video with text-to-speech voice generation, your own voice, and the AI’s support to create a customized script.

The platform also specializes in creating digital avatar agents (talking heads), which companies can personalize for explainer videos, customer support products, training support, and more. 

What is D-ID API?

API stands for Application Programming Interface (API). The D-ID API essentially links this AI tool’s capabilities with your existing software or website. 

When you send a D-ID API request, you can create digital talking heads and videos that you can later integrate into your CX system, chatbots, or online games. As you go up the pricing tiers, you can access premium API features like expression, voice, and pitch control.

Curious about how to get started with the D-ID API? We’ll cover the tech’s features and functionality, use cases, pros, cons, and alternative AI tools for you to consider. 

How does D-ID API work?

D-ID Api

The short version includes adding a face, choosing a voice, and generating your avatar or video. However, rendering an AI-generated talking head or video with D-ID API requires a few steps. 

Let’s break down the process, as inspired by the platform’s how-to video linked below: 

  1. Sign up for an account on D-IDAPI.com. 
  2. Generate an AI avatar.
    • Go to Account Settings
    • Generate your API key, copy it to your clipboard, and store it somewhere safe. 
  3. Go to the API Docs
    • Examine detailed descriptions and examples of API features.
    • Go to the Basic Authentication Section on the sidebar.
    • Ensure your generated API key is the header of every API request you make.
    • Create an authorization method in your Workspace
    • Paste API key 
  4. Make your first request
    • Create a talk with instructed code, including type, input, and source URL. 
    • Add a new request with the same endpoint to search for the response URL (the result)
    • Wait a few seconds to see your initial AI video
  5. Add a webhook for each request
    • Add a new endpoint and add its URL to the request payload. This shows in a new webhook field in your code
    • Press send. 
    • Track status field and ensure value is “done.”
    • Fetch output video from result URL.
  6. Create a video with a custom voice and style
    • Choose a text-to-speech provider: Amazon or Microsoft. 
    • Provide voice ID; browse supported voices, genders, styles, and languages in the voice gallery.
    • Select “Davis,” for example. Select Cheerful.
    • Add provider in your Script section in your original code. 
    • Go to Generate AI presenter tab and write a prompt to generate a custom portrait
    • Paste image URL in your code
    • Set Stitch param to “true.”
    • Type your script. Use ChatGPT to generate a custom script with your prompt
    • View your talking head with a custom image, tone, voice, and style.

More About D-ID API

Curious about pricing, alternatives, and more insight into D-ID? Keep reading for some frequently asked questions.

Can I use Studio D-ID for free?

Yes, but only during the free two-week trial. D-ID API pricing starts at $0 with the trial, then jumps to $18 for the “Build” tier. This tier includes up to 32 minutes of streaming video or 16 of regular video, up to 36 agent sessions for one agent, subtitles, and premium voices. 

Going up the tiers, you can access more agents, session time, video time, and premium features with the “Launch,” “Scale,” and “Enterprise” plans for $50, $198, and custom monthly pricing, respectively. 

Are there any free alternatives to Studio D-ID?

Most AI voice and video generation software don’t offer free plans that let you leverage the extent of its features. Still, you can try Studio D-ID’s free two-week trial for a time-limited, free alternative to its other subscriptions. 

What is similar to D-ID AI?

Tavus is similar to D-ID AI in its ability to generate customized voices and videos based on AI imaging and user inputs. However, it goes further in business potential with its batch videos that allow for scaling.

Choose the Right D-ID Alternative for Your Business

D-ID offers solid customization potential with voice styles and pitch control, as well as an API with 4X faster rendering time than real-time, at 100 FPS. Its API also gives you the flexibility to create digital talking heads from your own image or audio files. 

Still, the platform requires a decent amount of coding expertise to implement the AI. Alternatives like Tavus offer more user-friendly features to speed up the process. 

Additionally, Tavus is more appealing if you want an API with more voice cloning potential (including professional voice cloning) without D-ID’s requirement for enterprise pricing. It’s also a clear winner with scaling potential since you can auto-generate thousands of AI videos with personalized templates and machine learning that tweaks your inputted text and videos. 

Bottom line? Tavus offers a premium AI voice and video solution that meets every business’s needs. Ready to unlock personalized, scaled, AI video potential?
