Features of Synthesia


AI Video Avatars

Synthesia stands out with its extensive library of over 150 diverse avatars, providing users with a wide range of options to suit their needs. Among these avatars are the highly acclaimed “V3” avatars, which have undergone significant improvements, resulting in remarkably realistic portrayals. 

One notable feature is the ability to create custom AI avatars tailored to individual preferences, though this option comes with an additional cost of $1,000/year. This customization can be particularly appealing for users seeking a personalized touch in their video presentations.

Text-to-Speech Engine

A standout feature of Synthesia is its comprehensive text-to-speech engine, offering support for over 120 languages, accents, and voice tones. This extensive language coverage ensures accessibility and inclusivity for users worldwide. 

However, while the variety is impressive, the quality of voices can vary significantly across different languages and accents. To address this, Synthesia provides a custom dictation feature, allowing users to fine-tune pronunciation for optimal results. Despite occasional inconsistencies, this feature enhances the overall flexibility and usability of the platform.

Presentation Design Tool

Synthesia’s presentation design tool is designed to simplify the video creation process, offering a user-friendly interface reminiscent of popular presentation software like PowerPoint. With over 65 video templates and collaboration features, users can easily customize their videos to suit their branding and messaging. 

Additionally, integration with Zapier enables workflow automation, streamlining repetitive tasks and enhancing productivity. Despite occasional lag issues, particularly when generating longer videos, the platform’s intuitive design and collaborative features make it a valuable asset for content creators and teams alike.

Performance Testing and Verdict

In testing Synthesia’s performance, its avatars and voices impress with their realism and versatility. However, one notable challenge is the accuracy of lip syncing, which can sometimes lag behind the dialogue. Despite this limitation, Synthesia proves to be a valuable tool for corporate use, especially in internal communications and training videos. 

Its extensive language support and customizable features make it well-suited for addressing diverse audience needs. Overall, while there are areas for improvement, Synthesia offers a compelling solution for those seeking to streamline video production processes and deliver engaging content efficiently.
