Descript Overdub Review: AI Voice Cloning Feature

Today, I will walk through one of Descript’s coolest features for content creators: Overdub.

To get started with Descript’s Overdub feature, you have to submit your voice sample for training, and then the tool creates a text-to-speech model of your voice. From there, you can type in sentences, and a voice-over will be generated automatically of your very own voice.

Note: If you’re not looking to clone yourself, you can also use their library of high-quality stock voices too.

So how exactly does this feature work, and what are its pros and cons? You’ll find all your answers in this in-depth Descript Overdub review.

Let’s begin:

What is Overdub In Descript? 

Overdub is a special feature of the Descript video editing software that lets you clone your voice to create custom voice-overs by typing text in the editor. 

It uses Generative Adversarial Networks (GANs) to match your voice tone and synthesize it with general human speech patterns to generate high-quality voice output.

Descript also allows you to use its dozens of high-quality stock voices for generating and editing audio content.

Here are some possible use cases for Descript in content creation: 

  • Voice actors can use it to read out repetitive portions of their audio project.
  • Writers can become podcasters and can use it to create impressive-sounding long audio recordings without the expensive setups


The biggest benefit of Overdub is that you can correct voice recording mistakes by simply editing text. Before this, you were forced to record the whole audio again or trouble your editor to cover up the mistake.

How do you make an Overdub in Descript?

I’ll walk through the entire process of creating your custom Ai Overdub voice and using it for a given voice sample step-by-step. 

A quick disclaimer: Overdub is available only in English for the time being, and you can clone only your voice.

What Do I Need To Create Overdub Voice?

You need to submit at least 10 minutes of sample speech to the Descript Overdub portal so that it can process your voice within 1 day and generate your custom overdub voice. (It is recommended to submit 25 minutes + if possible)

Follow these tips to record a better-quality voice for sample speech:

  • Record your voice using a high-quality mic in a quiet room without background noise. Or, more importantly, record in the studio where you plan to record your final content.
  • Record between 20-50 minutes of your voice. Submitting hours of sample speech will worsen the voice output.
  • Speak as you would normally record for your audio and video content. The more natural your sample, the more natural your overdub will be.
  • You must submit your voice ID and formal consent to use your voice for the overdub. Ensure your voice ID matches your sample speech.

Here’s the best part:

You can upload multiple audio files for your sample speech as long as they sound similar and are registered in the same setting. In addition, descript overdub is smart enough to handle occasional mispronunciations in the sample, so you can continue recording despite speaking errors.

Is Descript Overdub Good: Pros and Cons

All and all, Descript Overdub is an amazing audio editing tool. You can shorten your learning curve in editing audio and video to a great extent and create amazing voiceovers without professional training. 

It is nothing short of magic when it comes to inserting quick punch-ins of forgotten words. However, longer sentences could still use a bit of humanization and improvement. That said, the program is bound to only get better, and it’s still pretty cool to make and hear your own Ai voice clone. 

I also found its stock voice options way better than Speechify, Google text-to-speech, and Speechelo. You can easily use Descript’s 7-day pro trial to see if it works for you.

Product Pros

  • Natural-sounding voice cloning for your podcasts and video
  • Effortless voice corrections by typing into the editor.
  • Nine high-quality stock voice options to choose from.
  • Privacy is secured with Voice ID.
  • Option to remove filler words and add emotion to engage listeners.

Product Cons

  • Some speech synthesis issues during long sentences.

Descript Overdub Review: FAQs

What is an Overdub voice?

Overdubbing, in the present context, refers to voice cloning technology that allows you to create a model of your voice to generate voice-overs on any given text. Research in text-to-speech started in the 1980s, with the earliest version of voice cloning applications being Apple’s Siri. 

Today you can submit your voice sample to dub your voice for hours of recording scripts using ai tools like Descript, Amazon Polly, and Real-Time Voice Cloning. We recommend Descript for better audio output and easy-to-use UI.

How does Descript Overdub work?

Descript Overdub uses Lyrebird AI based on the Generative Adversarial Network to generate natural-sounding audio from a given voice sample. It utilizes deep machine-learning frameworks to understand the general pattern of human speech from thousands of hours of training audio.

Once you submit your 30-40 minutes of voice sample, it matches its general understanding to find uniqueness in your voice to clone your tone for a given script.

Is Descript Overdub Free?

Descript’s free version allows  1000-word vocabulary overdubbing with “um” and “uh” filler word removal and 10 minutes of studio sound. 

Their pro plan starts from $24/mo, with unlimited overdub, over 18 filler, and repeated word removal. In addition, you can contact the Descript team to create a custom Enterprise plan for studio house requirements.

What are different Descript Overdub stock voices?

Descript offers 9 different natural-sounding stock voices in its Overdub feature, with 5 male voices: Don, Malcolm, Ethan, Henry, and Nicholas, along with 4 female voices: Emily, Carla, Ruth, and Nancy. You can play each voice before using it in your script.

What Are Descript Overdub Alternatives?

Different descript overdub alternatives include Amazon Polly, Google Speech Services, SpeechParrot, Real-Time Voice Cloning, and Natural Reader. All of these are great if trying to start a podcast. I found Descript overdub custom and stock voices much more natural than competitors, but you can always use their 7-day pro trial to find the difference yourself.
