Have you ever wondered what your favorite song would sound like if it was covered by a completely different artist? Thanks to recent advances in AI technology, tools now exist that can generate song covers sung by other singers, rappers, even fictional characters. In this comprehensive guide we’ll demystify the technical wizardry powering AI-generated vocals, survey some of the top services, and unleash our creativity with these fascinating new audio creation tools.
How Did AI Voices Get So Good?
To understand how AI services can realistically mimic human voices, we first need to recognize the key innovations that have transformed voice synthesis technology:
The Rise of Deep Learning
Early text-to-speech systems chopped up an inventory of vocal sounds to mechanically read phrases. This resulted in an unnatural, robotic tone. The shift to deep learning and neural networks fundamentally upgraded the realism of AI voice generation.
By analyzing thousands of voice samples, deep learning models discovered the complex spectral qualities intrinsic to each person‘s vocal signature. Modern services continue training neural networks on massive datasets – learning nuances that support far more human-like readings.
Few-Shot Learning
But training models requires substantial samples from each voice. Recording hours of audio from celebrities or acquiring rights is impractical. Few-shot learning breakthroughs now enable building realistic voice clones from just 3-5 minutes of audio.
For example, companies like Respeecher offer tools that finely tune a generic base model with a handful of custom samples. This unlocks access to many more voice types using limited data.
Modeling Expressiveness
Early models struggled with expressiveness. Even if they matched the technical aspects of a singer‘s tone, the delivery felt flat. Modern networks analyze the subtle variations as vocalists emote, learning to mimic their cadence and style.
Combining these innovations, AI services now generate increasingly plausible renditions where you can actually perceive a specific performer‘s flair. There are still clear limits – voice synthesis has a long path to perfectly replicating humans. But neural approaches have strengthened the artistry.
Why Create AI Song Covers?
Before surveying solutions, it‘s worth enumerating why users are eager to try such synthetic covers:
Novelty
We all get tired of overplayed hits. By reimagining popular songs with unpredictable combos we regain surprise – like kids gleefully breaking rules. The inherent novelty brings joy.
Humor
Comedy often relies on the unexpected. And comedians using voice tools as skit props demonstrate how silly altered songs tickle our funny bone through the juxtaposition.
Promotion
Covers also introduce different audiences to artists. A blogger sharing Drake impersonating Carole King pulls in some demographics unlikely to otherwise sample those performers. Conversion to fans has value.
Learning
Manipulating acoustic models – trying new mixes and combinations – strengthens our ears and musical understanding similar to any creative play.
Inspiration
Experimenting with synthesized samples sparks new ideas. Entirely original songs could emerge from fragments of novel covers. AI provides seeds of musical imagination that may blossom into fresh art.
Key Players Compared
Dozens of startups now offer AI vocal generation capabilities. I explored over 15 options, ultimately identifying 4 providers at the front of the pack pushing this space forward:
| Service | Key Highlights |
|---|---|
| Voicedub | +100 voice models + Text-to-speech + Voice cloning |
| Covers.AI | 🎤 BYOV custom models ✔️ Professional grade |
| Musify | 🎚 Editable outputs ⚙️ Quality controls |
| Vocalize | 🎶 Studio quality 🎤 Limited catalogue |
Below I share additional details on each service‘s technical capabilities and why they rank among the top solutions currently available.
Voicedub
Voicedub impressed me most with their catalogue – featuring over 100 voice models spanning celebrities, politicians, accents, and even fictional personas like Yoda or Santa Claus.
Beyond expected impersonators of music superstars like Ariana Grande and Kanye West, Voicedub also synthesized voices for Charles Darwin, William Shakespeare, and Buzz Lightyear which demonstrate artistic range.
I appreciated that Voicedub enables both uploading your own song or converting text into speech. This flexibility means you can create covers based on prepared tracks or quickly prototype ideas.
Audio outputs maintain enough fidelity to convey a convincing rendition of the source voice for many models. Listen to Voicedub‘s Aristotle covering Eminem for an amusing example.
With quality and depth rivaling other leaders, Voicedub edges out as the best all-around solution today. Their own blog shares fun concepts for curiously creative covers.
Covers.AI
Most services only offer pre-built voice models. But Covers.AI wisely recognized the demand for personalization – providing tools to upload anyone‘s voice for custom music impersonation.
With a few minutes of audio capturing your tones, Covers.AI can clone relatives, friends…even your pets! Training does take 12-24 hours before models are production ready. This positions Covers.AI not for quick experiments but rather long-term voice mimicry.
The cloning process impresses – both reconstructing technical qualities and playful inflections of a source sufficiently to suspend disbelief hearing them perform. Listen as this customer‘s macaw named Ghost covers Disturbed.
For those less patient, Covers.AI additionally offers a slate of recognizable pre-made models like Arnold Schwarzenegger and Morgan Freeman. Duet with legends for $20 credits (after free trials expire).
Built-in pitch and tempo editing also boosts creative options. Overall as the best BYOV solution, brands or influencers seeking an identifiable fake voice should train Covers.AI on their vocal DNA.
Musify
Musify attracted me by enabling not just AI cover creation but also post-generation editing to polish outputs. Tweaking pitch, smoothing transitions, and splicing multiple attempts provides welcome customization lacking in competitors.
Tools specifically for removing original backinginstrumentals or isolating the synthesized vocal track also assist using outputs in broader projects. Musify better supports serious editing work versus just novelty listening.
That said, the raw voice models seem more synthetic than rivals – with audible artifacts even on examples from pop divas like Taylor Swift and Rihanna. Musify promises upgrades in future, but for now editing really helps.
Pricing stays competitive with packages including 10, 30 or 60 cover renders monthly. Bulk discounts reward heavy musicians and content creators. Overall, the configurable toolset earns Musify its spot among leaders.
Vocalize
Lastly, the appropriately named startup Vocalize wins the title for best audio fidelity in synthetic singing. Even with few available voice models, those included replicate intricacies like Freddie Mercury‘s flamboyant embellishments with startling accuracy in this viral cover of Adele.
The gap between Vocalize‘s quality and competitors is instantly apparent. And yet with such limited options currently available, I hesitate naming them the singular best solution today. Just 5 artists may not sustain most users.
But Vocalize‘s foundations built on studying studio a cappellas scientifically capture nuances like breath control that elude rivals. As their catalogue expands to match technical prowess, Vocalize could claim pole position for discerning listeners valuing flawless productions.
Market Outlook
While most companies in this review focus narrowly on consumer entertainment, the voice AI industry seen explosive growth overall:
-
Funding topped $1 billion in 2021 across startups researching speech synthesis, vocal cloning, and adjacent voice tech [1].
-
Surveys found 76% of media executives now actively experiment with synthetic voices for some applications [2].
-

These statistics indicate a bright future for AI vocal generation apps as research continues advancing. What can developers still improve?
Future Needs
As remarkable as today‘s solutions appear, I see three frontiers requiring focus before AI can perfectly mimic human voices:
Expanding Model Catalogues – Even leaders sport far fewer offerings than the world‘s roster of captivating voices we‘d enjoy hearing perform special covers. Continually adding fresh voices is imperative.
Boosting Realism – Despite progress, artifacts still emerge betraying the synthetic origins on close inspection. Smoothing bridges between spliced vocal segments and better handling emotional crescendos will help.
Increasing Access – Integrations with more streaming platforms enabling sharing could vastly expand these tools‘ reach and inspire greater creativity. Rights complications slow partnerships currently.
Developers making strides on those vectors will push AI song mimicry towards ever more exciting artistic potential.
And companies must additionally ensure ethical practices around data collection, attribution, and responsible AI principles. With conscientious progress, even more listeners can delight in surprising new covers soon.
