You already know that AI-generated content is all around us. From the images we see online to the content we read - and of course, the audio we listen to.

However, when it comes to voices, our expectations for what AI should be able to produce are exceptionally high.

Why? 

Because our ears are very finely tuned to spot fakes.

Cadence, pitch, tone, intonation and pronunciation make a voice human. For brands and advertisers, passing computerised voices for human can be an embarrassing way to lose trust.

On the other hand, choosing text-to-speech voices synthesised with advanced AI tools can help them generate unprecedented quantities of high-quality audio content, saving countless hours (and costs) sourcing and recording voice talent.

As AudioStack connects creatives with many of the most advanced voice synthesis methods available, we’re well-positioned to tell you which AI voices can generate the most compelling creative.

What’s the difference between text-to-speech voices and realistic AI voices?

Before we get into our list, let’s clarify something important.

You may already have used text-to-speech (TTS) technology in your creative campaigns, heard that voice on TikTok, or implemented a TTS feature on your web platform - like the one that reads the articles published on a news website.

However, the text-to-speech platforms typically associated with these often produce robotic voices: lacking believable cadence, pitch, tone, intonation… everything that conveys emotion. 

For publishers and brands who know how something is said is as important for brand-building as what is said, it’s the fatal flaw of conventional TTS.

That’s just one of the reasons why the incorporation of AI into text-to-speech technology (led by providers such as ElevenLabs, IBM and Azure) is such a game-changer. With it, creators have a way to autonomously generate realistic-sounding voices with emotion: empathy, persuasiveness and authority.

Richer audio, and more of it. Now what?

Generating diverse, lifelike voices with different tones and cadences from a simple text script is a paradigm shift for text-to-speech. And with hundreds of American English AI voices - with thousands more global languages - in the AudioStack Library, you can certainly find the ones that are right for your brand.

But here’s the next thing: your agency, brand or publisher may be using realistic AI voices to make richer audio content at scale already.

And if you know that, you also know that the voice is just one part of the wider production puzzle.

If your methods for mixing, mastering and distributing content at scale are slow, it doesn’t matter how quickly you can write scripts and have AI recite voice lines back to you: you will still face the same bottlenecks.

That’s exactly why enterprise-level publishers, adtech companies, brands and their agencies rely on end-to-end, intelligent audio platforms like AudioStack, which:

• Automate scriptwriting, voice and music selection from simple prompts

• Employ intelligent AI features to mix and master audio (including noise suppression and echo cancellation)

• Empower users to safely and convincingly clone voices

• Generate multiple ads with variants at unprecedented scale and speed

We can tell you how it works, but it’s far more fun if you try making your next ad for yourself. And if you like what you can do with it for one ad, let's talk about how it can make your entire audio production workflow over 80% faster with AI.
