The Best AI Voice Generators: Unveiling Their Reliability and Realism

In recent years, AI voice generators have gained immense popularity, providing content creators with easier ways to create engaging content without having to record their voices every time. One of the most talked-about AI voice generators in the market today is ElevenLabs, which claims to offer the most realistic and versatile AI speech software. However, there are also hidden gems like Podcastle Revoice and previously popular options like Descript Overdub. In this comprehensive guide, we will evaluate and compare these three major AI voice generators, shedding light on their reliability and realism.

1. ElevenLabs: The Most Talked-About AI Voice Generator

ElevenLabs has gained significant attention and popularity due to its realistic and versatile AI speech software. The company prides itself on bringing compelling, rich, and lifelike voices to creators and publishers who seek the ultimate tools for storytelling. While ElevenLabs is highly regarded, it’s essential to test it out for yourself to determine if it aligns with your specific needs. From my experience using various voice generators, the most popular tool may not always be the best fit for everyone.

Creating Your Digital Voice with ElevenLabs

The process of creating a digital voice using ElevenLabs is straightforward. You have two options: using a premade voice or customizing the voice settings. With a variety of premade voices to choose from, you can create even more variations. If you prefer, you can also add your own voice by following the instructions provided. Once you’ve selected the voice and entered the desired text, simply hit “Generate” and wait a few seconds for ElevenLabs to process the audio. You can then download the generated audio from the “History” tab.


ElevenLabs offers a free plan that includes 10,000 characters per month and allows you to create up to 3 custom voices. For more extensive usage, they offer a $5/month plan that provides 30,000 characters per month and allows you to create up to 10 custom voices. Additionally, ElevenLabs has premium subscription options tailored to independent publishers and growing businesses.

My Take on ElevenLabs

While ElevenLabs’ AI model is groundbreaking and different, I found that the AI-generated voice didn’t sound like mine. It lacked the confidence and authenticity I desired for creating content instead of using my own voice. However, I have come across incredible recordings done entirely with ElevenLabs that nearly fooled me, showcasing its potential. Nevertheless, it’s essential to note that ElevenLabs may not yield the same results for everyone and has limitations when it comes to capturing accents accurately.

2. Podcastle Revoice: A Hidden Gem for AI Voice Generation

Podcastle Revoice utilizes generative AI technology to enable users to create a digital copy of their own voices. This feature allows content creators to generate content using their unique voice wherever they want.

Creating Your Digital Voice with Podcastle Revoice

To create “My Digital Voices” with Podcastle Revoice, you need to have a Pro subscription. The process involves clicking on “My Digital Voices” and selecting “+ Create voice.” You will then be prompted to record short sentences through 70 prompts. This unique audio prompts submission aims to create a variation of vocabularies. After completing the prompts, your new digital voice will be available within 24 hours. To use your digital voice, create a new project, choose “Convert Text to Speech,” enter your desired text, and select your voice.


Podcastle offers an all-in-one podcast recording and editing platform, and access to Revoice (AI voice cloning) is included in the Pro version, priced at $23.99 annually or $29.99 monthly.

My Take on Podcastle Revoice

Having previously written about Podcastle Revoice during its beta launch, I found the feature intriguing and enjoyed the process. According to Podcastle, they have improved their algorithm, resulting in better quality voice generation. While my digital voice from Revoice sounded somewhat like mine, it had a more robotic tone compared to ElevenLabs. For long-form content, I would lean towards ElevenLabs to ensure a more natural flow of speech. However, Podcastle remains an excellent choice for podcast recording and editing.

3. Descript Overdub: A Powerful AI Voice Generator

Descript’s Overdub is another notable AI voice generator that allows users to create a text-to-speech model of their voice or select one from their ultra-realistic stock voices.

Creating Overdub with Descript

To use Overdub, you need at least 10 minutes of recorded speech, although Descript recommends 30 to 180 minutes for high-quality results. After submitting your training session, which may take 2-24 hours for review, you can add a Voice ID, which serves as a consent statement if you’re submitting someone else’s voice. Overdub offers a free option with a 1,000-word vocabulary, but for more extensive use, upgrading to the Pro subscription at $30/month is recommended.

My Take on Descript Overdub

I find Descript Overdub impressive in terms of ease of use and setup. The generated voice can sound quite natural, making it worth exploring alongside ElevenLabs. While slightly more expensive than ElevenLabs, Descript offers a suite of features that can be beneficial for podcasters and content creators.


Determining a clear winner among these AI voice generators may be subjective. While ElevenLabs is widely regarded and popular, it’s crucial to explore other options like Descript Overdub and keep an eye on Podcastle Revoice’s future developments. When choosing an AI-generated voice, factors beyond the basics, such as timing and intonation, come into play. Exploring these options can be both exciting and beneficial for creators. As the market offers numerous AI tools, it’s essential to have fun while learning and experimenting with them.
