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.

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?
