10 Best Sieve Alternatives For Voice Generation In 2025

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).
