10 Best HeyGen Alternatives & Competitors In 2025 [Reviewed]

Are you searching for a HeyGen alternative to dub videos, generate speech from text, or clone your voice to create human-like content at scale?

HeyGen offers an AI voice generator that turns text into videos using realistic avatars that can be customized to use certain expressions, talk in different languages, and interact as you want them to.

However, some customers are not happy with the platform’s limited avatar diversity and voice options that struggle to convey the desired emotion (i.e., sound robotic).

I analyzed 30+ AI voice generation and dubbing solutions, looked at verified customer reviews, and talked to real content creators to build a list of the ten best HeyGen alternatives in 2025.

TL;DR

• The best alternative to HeyGen in 2025 is Camb AI for teams looking to localize content into 140+ languages, while retaining the original speaker’s voice and emotion.
• Tools like Synthesia and Colossyan are ideal for content creators who want to produce localized, multilingual videos with diverse AI avatars and smooth lip-sync capabilities.
• On the other hand, platforms such as Rask AI and PlayAI can help you scale dubbing and voice generation with emotional depth, voice cloning, and advanced localization features.

In this honest guide, I will cover each tool’s features, pricing structure, pros & cons, and use cases to help you make a more informed decision.

Before we start, I want us to go over why some video content creators are considering switching from HeyGen: ⤵️

Why are some content creators looking to switch from HeyGen?

Many creators are seeking alternatives due to HeyGen’s limited avatar diversity, robotic intonation, and voice options that lack emotional nuance or natural pronunciation in non-English languages.

Now, don’t get me wrong, I’m not claiming that HeyGen is a terrible product that should be switched from. 

There are hundreds of customers, if not thousands, of the solution that are more than happy with how they can create custom avatars for voice generation (they even have interactive avatars).

After all, the tool supports translation and voice cloning in 175+ languages and has good video draft editing.

Despite this, some users of the platform have been dissatisfied with the AI dubbing solution for several reasons:

#1: Limited avatar diversity

The main complaint on HeyGen has been its limited avatar diversity, as some users of the platform have expected to see more diverse avatar templates with varying ages, ethnicities, and styles.

According to one verified user of the platform, more diverse templates will help them tailor their content to a wider audience.

‘’More diverse avatar templates (e.g., varied ages, ethnicities, or styles) would help tailor content to wider audiences.’’ – G2 Review.

#2: The avatars can feel robotic

Next up, users of the tool mention that, at some times, the avatar’s intonation can feel slightly robotic in longer texts, as a G2 user puts it, especially with more complicated emotions.

‘’Occasionally, the avatar’s intonation still feels slightly robotic in longer texts, especially with complex emotions. It would also be great to have more customization options for gestures or hand movements to increase expressiveness.’’ – G2 Review.

#3: Some voice options don’t convey the desired emphasis, pronunciation or emotion

Last but not least, customers of the platform mention that some of the voice options do not convey their desired emotions.

A verified customer of the platform also mentions that the avatars’ pronunciation of some words in non-English is not as natural-sounding as it can be.

‘’Finding the right tone of voice can be challenging, as some voice options don’t always convey the desired emphasis or emotion. Additionally, the pronunciation of certain words in languages other than English could be more natural and precise.’’ – G2 Review.
