Have you been looking for an alternative to Sieve to dub videos, generate speech from text, or clone your voice to generate video content at scale?

Sieve’s video and audio processing platform integrates advanced models like ElevenLabs to offer content creators voice dubbing, lip sync, background removal, autocrop, and active speaker detection.

Despite this, I found the tool’s pricing to be rather expensive when compared to other alternatives on the market, while having limited customization capabilities and no real-time voice synthesis.

I went over 30+ AI voice generation and dubbing solutions and talked to real content creators to build this list of the 10 best Sieve alternatives for video content generation and editing in 2025.

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

TL;DR

• Camb AI offers the best alternative to Sieve with its advanced dubbing, minimal-data voice cloning, and localization capabilities in 140+ languages, while retaining the original speaker’s voice and emotional tone.
• Versatile tools like Murf AI and ElevenLabs are ideal for solo creators and small teams who need realistic multilingual voiceovers, audio content generation, and fine control over intonation and style.
• On the other hand, platforms like HeyGen and Synthesia can help you create interactive talking head videos and customizable AI avatars, which are perfect for storytelling, training, and education use cases.

Before we start, I want us to start with the reasons why some content creators have been considering making a switch from Sieve: ⤵️

Why are some content creators looking to switch from Sieve?

Some content creators are looking for alternatives due to the platform’s expensive pricing model, limited customization options, and the fact that it does not offer real-time voice synthesis for streaming.

But don’t get me wrong here, I’m not trying to say that Sieve is a bad product that you should run from.

The platform might be brand new to the point where it does not have G2 or Capterra reviews, but there are satisfied users with its end-to-end video shipping speed.

Despite this, I found the following bottlenecks of the platform that are making existing and potential customers think twice: ⤵️

#1: Expensive when compared to the original source

Sieve offers a custom pricing model that charges you $0.535/min for ElevenLabs and $0.402/min for OpenAI voices (API), while those services cost ~30–70% less when used directly.

💡 This markup can become unsustainable and rather expensive for high-volume users who have simpler needs.

#2: Limited customization options

Next up, users can’t easily train or clone voices on Sieve – you'll be limited to what OpenAI or ElevenLabs offer.

There’s no apparent support for custom voice datasets or fine-tuning that I could find on the website, either.

➡️ What I’m worried about here is that I wouldn’t be able to control how the voices come off emotionally.

#3: No real-time voice synthesis

Lastly, I’m not happy with the fact that Sieve does not offer real-time voice synthesis as an enterprise-grade solution.

Sieve processes batches asynchronously, so it’s not suitable for real-time voice applications (e.g., streaming, chatbots, or voice agents).

Our voice generation platform uses advanced speech and language AI models to translate spoken content into different languages to retain the speaker’s original voice and emotion.

Full disclosure: Even though Camb AI is our platform, I’ll provide an unbiased perspective on what makes us the best Sieve alternative on the market in 2025.

Here’s what you can expect from Camb AI:

• Natural voice retention of the original speaker’s original voice, emotion, and tone.
• Lip-sync accuracy that aligns your mouth movements with translated speech.
• Voice cloning replicates the speaker’s vocal characteristics to provide a consistent and authentic voice.

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

Video Dubbing at Scale Without Losing Quality

Camb AI offers an enterprise-grade video dubbing software that helps media brands add voiceovers to their 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 translated a YouTube video in Spanish (feel free to use our Chrome Extension that lets you dub YouTube videos automatically):

💡 After dubbing, 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.

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

💡 You can see how easy it is to turn any video into a global sensation by dubbing it into multiple languages, all in just a few clicks:

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).

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

Our team 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.

Text-To-Speech Designed For Multilingual Synthesis in 140+ Languages

Camb AI helps video content creators and media brands easily convert written text into lifelike speech.

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

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

Our voice generation software 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 tool separates the original voice from the background music or sound effects by using voice isolation and re-integration.
• Multi-speaker scene handling for when brands need to have more than one speaker. Our software 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.

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

• Translated and emotionally matched voiceover.
• Music and effects left 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. 

💡 Our team partnered with IMAX to translate their original content & documentaries.

Stories Creation: Create & Translate Audiobooks

Lastly, our solution lets you unleash your creativity with Camb AI by creating stories that will resonate with your target audience.

➡️ You can upload your script, choose your preferred languages and AI voices (you can also add your voice 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, your team will be able to:

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

And the best thing about it?

Your team can localize it to different languages, effectively translating their audiobook for the world to listen to their content.

We designed this to help storytellers like you 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.

💡 You can see how easy it is to turn your script into a multilingual audio story, complete with natural-sounding narration:

‍

‍

Users of our platform 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 Sieve?

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

• Dub content in 140+ languages (including low-resource ones like Icelandic, Swahili), whereas Sieve currently focuses on major global languages only.
• Leverage zero-shot dubbing with Camb’s proprietary MARS5 & BOLI AI models to preserve pitch, tone, and emotion — Sieve requires speaker data or fine-tuning for best results.
• Access real-time dubbing for long-form content and live events, while Sieve’s workflows are optimized for short-form, async media.
• Get native-sounding translations that include idiomatic phrases and emotional nuance, while Sieve’s translations often require post-editing for tone and fluency.

➡️ Camb AI is best for global media teams needing high-fidelity dubbing with emotional preservation and low-latency workflows.

➡️ Sieve is best for AI-native creators and startups looking for fast, simple localization of short-form content and reels.
