Looking for Synthesia alternatives to dub videos, generate speech from text, or clone your voice to create human-like content at scale with an avatar?

Synthesia helps you translate and dub videos into 29+ languages in minutes, preserving your original voice and ensuring perfect lip sync.

However, some users of the tool are not satisfied with the platform’s limited avatar customization, the big price gap between paid plans, and how unnatural the avatars can be at times.

I sifted through 30+ AI voice generation and dubbing solutions, looked at verified customer reviews, and talked to video content creators to build this list of the ten best Synthesia alternatives for video generation in 2025.

In this detailed 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 discuss why some video content creators are considering switching from Synthesia: ⤵️

Why are some video content creators looking to switch from Synthesia?

By no means am I saying that Synthesia is a bad video generation tool that you should run from. In fact, there are hundreds (if not thousands) of content creators who are happy with it and have been using it for more than a year.

The tool lets you translate any uploaded video into 29+ languages in minutes while retaining each speaker’s original voice.

Despite this, some customers have been dissatisfied with the platform for several reasons:

#1: Limited character customization

The #1 issue for users of Synthesia has been its limited avatar customization, which can make them feel robotic.

One user of the platform notes that their team did not have many options to customize the speech, pronunciation, and delivery of the avatars.

‘’Limited character customization. Avatars can feel robotic. You don't have many options to customize the speech, pronunciation, and delivery.’’ – G2 Review.

#2: Big price gap between plans

Another recurring complaint was about the big price gap between Synthesia’s paid plans, which left medium-sized enterprises wondering what they could do about it.

Synthesia’s creator plan costs €58/month when billed annually for 360 minutes of video a year (not a month), which has left some users asking for enterprise pricing, which has reportedly been in the thousands per month.

‘’Huge price gap between the self-service Creator plan and the Enterprise + Agency plans. A new plan bigger than Creator and smaller than the Enterprise would be a nice fit for some customers.’’ – G2 Review.

#3: Avatars do not look as natural as they could

Last but not least, customers of Synthesia are not happy with how unnatural some of the avatars look, especially their eye movements and corrections.

This kind of defeats the purpose of avatars since they are supposed to mimic life-like behavior, and can break the ‘’immersion’’ in your viewers.

‘’The only challenge I’ve faced so far is with the avatar’s eye movement/correction, which hasn’t looked entirely natural in some cases.’’ – G2 Review.

#1: Camb AI

Camb AI (that’s us) offers the best Synthesia alternative for AI voice dubbing and localization on the market for video content creators looking to dub and localize content into 140+ languages.

Our platform uses advanced speech and language models to translate spoken content into different languages, while retaining your original voice and emotion.

Full disclosure: Even though Camb AI is our AI voice generator, I’ll provide an unbiased perspective on what makes us the top Synthesia alternative on the market.

Here’s what you can expect from Camb AI:

• Natural voice retention: Our AI voice generation software maintains your original voice, emotion, and tone to create a resonating message for your international audience.
• Lip-sync accuracy that aligns mouth movements with translated speech to create a visually engaging experience.
• Voice cloning: The tool replicates your vocal characteristics to provide a consistent and authentic voice.

Let’s go over the features that made IMAX, AWS, Major League Soccer, and Australian Open partner with us to localize their stories, videos and live streams: ⬇️

Video Dubbing

Camb AI offers an advanced AI-powered video dubbing platform that lets you add voiceovers to your videos for a polished, professional touch.

Our multilingual voice dubbing platform converts speech from one language to another with voice cloning, intending to preserve your emotional tone.

For example, I was able to translate a YouTube video in Spanish (you can also use our Chrome Extension that lets you dub YouTube videos automatically):

💡 After the dubbing of the content, you’ll see ‘’Warnings’’ on dialogues that have speedups, slowdowns, a lack of a speaker, or a nudge to adjust timestamps to improve the quality of your output.

➡️ We make multilingual broadcasting accessible using AI technology for broadcasts that were originally in English only to help you bring them to the world.

For example, our team worked with the Australian Open to host the world's first sports event to use AI dubbing with DubStream (our tool for real-time translation & dubbing of live broadcasts).

Our solution helped them set up post-match conferences in multiple languages. Interested in watching Djokovic's viral moment in Spanish?

We’ve also recently launched our newest AI model, MARS5, that enables vocal performance transfer using just 2-3 seconds of your audio.

MARS5 is capable of replicating the speaker’s identity, style, prosody and nuance in over 140+ languages cross-lingually.

Camb AI’s advanced AI model combines an autoregressive model with a novel non-autoregressive model to produce speech and audio to capture emotion, meaning, and performance like never before.

You can learn more about MARS5 from our CEO here:

➡️ Take our video dubbing functionality for a test drive by uploading a file and selecting the source language and target language.

Text-To-Speech

Camb AI helps you easily convert written text into lifelike speech.

Our text-to-speech functionality is designed for multilingual synthesis in 140+ languages with voice retention.

Unlike Synthesia, our TTS comes off as emotionally and contextually aware with minimal data voice cloning (with as little as 5 seconds of your audio).

Our platform doesn't just generate clean voice audio; Camb AI aims to generate voice that is precisely timed and mixed to fit within existing media tracks.

That includes:

• Voice timing alignment: Camb AI ensures that the synthesized speech matches the timing of your speaker, even across languages with different word lengths (e.g., German vs. English).

➡️ Voice timing alignment is crucial for keeping lip-sync, subtitle timing, or background effects (like sound cues) intact.

• Background audio and emotion preservation: Our platform separates the original voice from the background music or sound effects by using voice isolation and re-integration.
• Multi-speaker scene handling for when you need to have more than one speaker. Our solution can identify each speaker via speaker diarization and clone + replace their voices.
• Colloquial fluency: Your team can deliver native-sounding results to adapt to idioms and your cultural expressions.

Imagine that you have a marketing video with a background music track, an English-speaking narrator, and ambient sound effects.

With Camb AI, teams can upload the video or audio, choose their target audience, and get a fully dubbed version with:

• Translated and emotionally matched voiceover.
• Music and effects untouched.
• Synchronized pacing and subtitle timing.

➡️ Take our text-to-speech functionality for a test drive by adding your content, selecting from our speakers, the gender, and target language. 

💡 We partnered with IMAX to translate their original content & documentaries, as featured on TechCrunch.

Stories Creation

Lastly, our platform lets you unleash your creativity with Camb AI by creating compelling stories.

➡️ You can upload your script, choose your preferred languages and AI voices (you can also add your custom clone) and Camb AI will translate the story and generate expressive voiceovers with emotional depth.

For example, I uploaded a PDF of a book called ‘’The Fully Raw Diet’’, which aims to educate readers on how to adopt a vegan diet.

After the transcript is ready, you can:

• Add or create your voice clone.
• Adjust pauses.
• Add and/or edit dialogue.
• Set the tonality.

And the best thing about it?

You can localize it to different languages, effectively translating your audiobook for the world to listen to your content.

We designed this to help storytellers generate full multimedia narratives by combining script writing, translation, voice cloning, and dubbing.

It combines our multilingual synthesis, expressive voice generation, and contextual translation to output ready-to-use audio stories.

Customers of ours have been using it to create:

• Language learning by generating parallel-language versions of the same story to help learners hear and read translations.
• Corporate training by building a narrative-driven onboarding.
• Animated or narrated storytelling content that reaches a global audience on YouTube.
• Audiobook samples by generating multilingual previews with different narrators and emotional tones.

➡️ Take our story creator for a ride by adding your content, source language, and narrator voice.

How Is Camb AI different from Synthesia?

Camb AI does not offer traditional digital avatars; our tool’s focus is on natural, expressive speech synthesis rather than on creating talking‐head videos.

💡 Both platforms let you dub content in 140+ languages, but Camb AI’s BOLI model focuses on idiomatic, culturally accurate translations, while Synthesia offers straightforward 1-click localization for video scripts.

Unlike Synthesia, Camb AI’s voice generation platform lets you:

• Can handle multiple speakers within a single video (accurate voice cloning even if several people speak, up to 100).
• Get access to zero-shot dubbing (an advanced technique in speech synthesis) across dialects via our MARS & BOLI models that capture your pitch, tone, and emotion.
• Get access to our DubStream solution for real-time translation & dubbing of live broadcasts. Synthesia focuses on editing prerecorded videos.
• Get native-like translation with idiomatic handling and emotion mapping, which users found to be one of Synthesia’s main weaknesses.

➡️ Camb AI is tailored for brands that require:

• Maximum voice & ambient preservation, so dialogue and background sounds stay true to the original.
• A wide range of advanced audio tools (e.g., stem separation, text-to-sound) for fine-grained control.
• Live-event or film dubbing capabilities (via DubStream and MARS & BOLI models) to handle real-time translation/dubbing or multi-speaker scenarios in movies and events.

Camb AI’s Pricing

To learn more about Camb AI’s pricing, you’ll need to contact us to get a product demo and a quote.

However, you can get started with our platform for free with limited credits, so you can play around with the tool.

Pros & Cons

✅ Clone any voice across 140+ languages while keeping its original tone and style.
