Synthesys review.

Videos have become an essential element in marketing, generating 1200% more shares than text content.

Nevertheless, producing videos may be more time-consuming and expensive than one might think, especially when considering the expenses associated with renting a studio, getting the right lighting, purchasing high-end equipment, hiring a spokesperson, and more. This becomes even more challenging when you want to produce videos at scale.

Thankfully, with AI video generators like Synthesys, you can generate captivating videos simply by typing the text.

But that's not all Synthesys is capable of: it also has some new and powerful features, like the AI Voice and Image generator, which I will test personally. After that, we'll discuss the pros and cons of using Synthesys, pricing options, and alternatives.

By the end of this comprehensive Synthesys review, we'll explore why it is considered one of the top AI video generators on the market and determine if it is worth the investment.

What is Synthesys?

Synthesys homepage.

Synthesys is an AI-powered video generator with advanced technology to produce realistic and natural-sounding voiceovers using real human voices. Simply type the text, and Synthesys will use its Text-to-Speech (TTS) technology to transform it into high-quality voiceovers.

This powerful tool has an extensive library of over 300 voices in 140 languages. You can customize the voice exactly to your liking by selecting the emotion, such as cheerful, angry, or sad, and adjusting the pitch, emphasis, and pauses.

Using Synthesys' Text-to-Video (TTV) technology, choose from more than 80 avatars to lip-sync what you type. There are also over 50 templates to match your branding and make visual customizations by adding subtitles, images, text, shapes, and more.

In addition to its impressive voice generation capabilities, Synthesys offers an AI Image generator that uses algorithms to generate realistic images based on text inputs. This feature allows you to bring your ideas to life by creating visual representations of your concepts without the need for graphic design skills or expensive software.

Synthesys is great for creating all types of video content, including sales videos, How-To guides, social media posts, TV commercials, podcasts, and more. If you want to save time and money or are too shy to get on camera, Synthesys is the perfect solution.

Let's take a closer look at the main features offered by Synthesys and test them first-hand.

Synthesys Key Features

Here are the latest features of Synthesys which I have personally tested and used:

  • AI Voice Generator
  • AI Video Generator
  • AI Image Generator

AI Voice Generator

Using the AI voice generator in Synthesys.

Step into the future of voice generation with Synthesys' AI Voice Generator! It has a sleek and user-friendly interface with an impressive collection of over 300 voices in 140 languages.

No need to worry about robotic and monotonous voices: Synthesys offers a wide range of synthetic human voices that can convey many emotions ranging from fiery anger to heartwarming cheer and heart-wrenching sadness. Tweak the settings easily by adjusting the Rate, Pitch, Emphasis, and Pauses to create the perfect tone for your project.

There are no limits to your creativity, as Synthesys allows you to unleash your imagination with unlimited text input. The Multi-Voice functionality also lets you create conversational voiceovers using different voices for various sentences within a single audio file.

As you can see, I selected two voice actors in the same audio file to start having a conversation with each other:

Synthesys makes everything easily accessible and organized when working on multiple projects by saving everything to My Studio. Plus, you can quickly and easily download the voiceovers and embed them seamlessly into any website.

If that's not enough, Synthesys' AI-powered assistant (the speech bubble in the bottom right corner) is a ChatGPT-like conversational AI chatbot equipped with the latest answers from Google. It generates hyper-relevant, factual, and up-to-date content, meaning you can produce unique and captivating copy for both AI voices and humans across 24 languages.

I asked the Synthesys AI Writer a question and, in seconds, had an answer that I can now use as copy:

From my experience, everything within Synthesys' AI Voice Generator is seamless. The interface is clean and user-friendly, it's very flexible, and you can access countless voice actors ranging in age, gender, ethnicity, nationality, language, mood, etc.

When playing back the copy I had written, everything sounded authentic and flowed seamlessly, as if an actual human had said those words. It's the perfect solution for saving time and money on hiring voice actors or doing voiceovers yourself, and this is just one example of how AI business tools are transforming the way we approach tasks that used to require a human touch.
