Rap and hip-hop have evolved tremendously over the years. What started as rhythmic poetry set to funky beats on the streets of New York has transformed into a global multi-billion dollar industry. As rap embeds deeper into mainstream culture, artificial intelligence (AI) is stepping in to lend some silicon vocal cords. Let’s check out the most promising AI rap voice generators and how they stack against their human counterparts when flowing over phat beats.
Can AI Rap?
Believe it or not, today’s AI algorithms are getting scarily good at mimicking rap vocal styles. Thanks to deep learning and neural network advances, they can analyze tons of rap lyrics and vocal recordings to generate surprisingly coherent flows. Of course, work must be done before AI rappers drop Grammy-worthy bars. But the early results are impressive.
Current AI rap generators use techniques like recurrent neural networks (RNNs), generative adversarial networks (GANs), and transformer models to study rhyme, rhythm, vocabulary, and more. This gives them the basic building blocks to independently piece together passable rap verses. With enough data to learn from, they can adopt different rapper personas and adjust their tone and style. Let’s look at some of the top contenders pushing AI rap forward.
Rappers Meet Their Automated Match
ALYSIA – The AI Lyricist
ALYSIA AI rap voice generator made waves in 2020 as one of the first AI systems that could freestyle rap competently. Built by AI startup Anthropic using Constitutional AI techniques, ALYSIA absorbs many lyrics from artists like Kanye West, Jay-Z, and Eminem. She then uses what she learns to rap coherently on topics given to her.
While far from a lyrical wordsmith, ALYSIA impresses with decent rhyme schemes and rhythmic delivery. She even threw down against real-life rapper Dovy in a rap battle, managing some slick rebuttals to his disses. As an early effort, ALYSIA sets the stage for bigger things to come. The AI rap game is just getting started.
DeepRapper – Straight Outta Silicon Valley
In 2017, researchers at the University of Antwerp in Belgium developed an AI system called DeepRapper. It uses a recurrent neural network and silver tongue analysis to generate original rap lyrics one line at a time. While far from the poetic brilliance of Kendrick Lamar, DeepRapper can craft decent rhyming verses tailored to a specific artist.
Feed over 12,000 lyrics from rappers like Eminem, Kanye, Lil Wayne, and 2Pac. DeepRapper begins recognizing their styles. Ask it to rap like Kanye, and you’ll get automation trying its best Yeezy impersonation. The same goes for channeling Slim Shady’s inner madness. It’s an early step toward customizable AI rappers.
Daddy Kev’s AI Rapper – Old School Flow
In 2021, music producer Daddy Kev trained an AI rapper using raw cappella tracks from iconic acts like Run-DMC, Beastie Boys, LL Cool J, and Public Enemy. Focusing on 1980s and 90s hip-hop vocals gives Daddy Kev’s AI an old-school flow. Once trained, it can generate original verses that capture classic vibes.
Rather than just mimicking lyrics, Daddy Kev’s AI absorbs vocal textures, cadences, and rhythms. The result sounds unique to AI, with an organic delivery that hits the right nostalgic notes. Now, he’s exploring blending the AI rapper with human vocals for seamless collaborations—the past and Future of hip-hop colliding.
Google Magenta RAP – AI’s Raw Rap Skills
In 2018, Google’s Magenta AI team introduced the Robust AutomatedProgramming system for rapping, aka RAP. It uses a GRU neural network to analyze raw cappella tracks and acapella instrumentals to generate its lyrics and rhythms from scratch.
Unlike some AI rappers that rewrite existing lyrics, RAP builds its verses using machine learning algorithms alone. While currently limited to short 4-bar loops, RAP shows surprising creativity and vocabulary for AI. It even throws in ad-libs like “yeah!” and “uh-huh!” to sound more human. RAP could potentially drop full songs of shockingly original machine-made flows if scaled up.
Meta’s RAPID Model – Blending Human and AI Vocals
Meta AI researchers recently developed an “application” model called RAPID. It analyzes human rap vocals and then generates AI flows that complement them. Instead of writing full rap songs alone, RAPID aims to blend with human collaboration seamlessly.
The researchers had RAPID study rappers like Post Malone, Kendrick Lamar, and Dilated Peoples. It uses transformer networks to develop an AI rapper that meshes with specific human vocals. Rather than robotic imitation, RAPID maintains its style while filling gaps and matching cadences. The human starts, RAPID replies, back and forth. AI and rappers could make beautiful music together.
The Outlook for AI Rappers
Current AI rap generators are impressive, considering they started from scratch. With further training on more enormous datasets, they’ll keep improving their vocal styles, rhyme schemes, rhythmic timing, and linguistic skills. Some limitations still need addressing, though. Let’s look at what the Future may hold for AI rappers.
More Training Data = Better Flow
Like any machine learning system, today’s AI rappers are only as good as their training data. Most start with lyric scrapes from Genius or Rap Genius to learn from. But studying text alone misses vocal rhythms, textures, and expression. Ideally, AI needs a giant dataset of raw rap vocals from diverse artists to master the intricacies of flow.
Luckily, the availability of cappella tracks is exploding thanks to sites like tracking. With sufficient high-quality training data, AI rappers can capture styles more accurately. Imagine an AI replicating E-40’s slippery swagger or André 3000’s melodic versatility through end-to-end vocal training. More data unlocks next-level linguistic nuance and fluidity.
Custom AI Rappers
Today’s AI rappers take an impersonal, one-size-fits-all approach. But imagine customized AI tailored to your rap persona. Provide enough vocal samples in your style, and AI could generate bars that sound naturally yours.
This opens possibilities for AI rap features, background vocals, ad-libs, and more in your songs. Beyond music, personalized AI rappers could become video game characters, virtual avatars, voice assistants, and other applications where they rap in your distinct voice. As AI improves, you may hear your words rapping back at you.
Rap Duets between Humans and AI
We’re already seeing AI rap voice generator systems that complement human vocals rather than simply mimicking them. A big next step will be AI rappers that can trade bars back and forth with humans in real time. Imagine AI responding to your rhymes, dissing you, or finishing your punchlines.
Human and AI rappers playing off each other could unlock new creative possibilities in songwriting. Cutting with machine intelligence could help human rappers write tighter verses and become better lyricists. The Future of rap could be an organic fusion between silicon and carbon vocal cords.
Next-Gen Rap Lyrics and Production
Beyond just mimicking pre-existing styles, truly creative AI rappers could generate groundbreaking new flows, rhyme techniques, cadences, and lyrical styles. They have the potential for nearly unlimited original output, unburdened by writer’s block that restricts human rappers.
AI beatmakers are also making giant strides in designing instrumental tracks from scratch. Together with rhyme-bot lyricists, AI producers could generate entire rap songs or albums without direct human input. In the coming years, we may hear machine-made hip-hop that sounds shockingly fresh and new. Who knows what novel rap styles AI coders can unlock?
Unique AI Vocal Textures
Even the most advanced AI rappers still sound somewhat robotic and synthetic compared to humans. They lack the subtle grain, rasp, and grit that make for compelling rap vocals. However, the creative processing of AI voices could lead to some unique textures.
Look how autotune, pitch shifting, distortion, and other effects transformed Travis Scott’s and Future’s vocals into something genre-defining. Similarly, inventive processing and filtering on AI rappers could give them a distinctive aesthetic. Rap fans may one day eagerly anticipate new sounds from their favorite robotic MCs.
AI-Human Collaborations
Rather than AI simply mimicking rap or replacing rappers, the most exciting Future is one of collaboration. AI’s untiring output and inhuman vocal textures complement human creativity, emotion, and life experiences. Matches like that could birth novel hip-hop hybrids.
For example, AI might spit out 1000 draft bars, then a human editor whittles them down to the illest 16. Or a human rapper lays the verses with AI, generating a mind-bending alien chorus. AI beatmakers and human producers could also fuse machined grooves with live instrumentation. Blending AI and human skills will unlock creative possibilities we can’t yet imagine.
