It's hard to write vocal choirs from scratch. Producers go crate digging and fish through sample marketplace to look for something that matches their project. This can come at a high cost, if they need to pay royalties on that audio. It also exposes them to redundancy, if other artists sample the same vocal choir.
AI choir generation tools solve this problem by creating a huge vocal sound, without the need to license of techniques, from text-to-choir generation to voice-to-choir timbre transfer.
It may be tempting to use apps like Suno and Udio, considering they are the goto AI music generation tools in 2026. But AI generated outputs from both tools are watermarked, an ownership terms are unclear. As of January 2026, Udio no longer supports downloading outputs. Ownership of Suno outputs is also questionable.
Companies like Controlla and Kits offer cost effective alternatives for choir generation, with models that were fine tuned on licensed music. Dreamtonics and Ace Studio offer more advanced, professional choir tools. MIDI piano rolls, vocal articulation control, and multilingual support.
This article addresses the simple and advanced options, with some demos and illustrated walkthroughs to help you imagine how the workflow actually looks. I'll share non-affiliate links to each company as well, so you can explore further.

Professional AI Choir Tools: Synth V 2 Pro, Ace Studio
There are two major competitors in the professional AI choir generation space; Dreamtonics Synthesizer V Studio 2 Pro and Time Domain's Ace Studio 2.
Dreamtonics added three new AI Choir Voice Collections to Synth V Studio 2 Pro in January 2026. These updates include support for up to 16 singers at a time with a blended choral timbre that you don't get from stacking 16 solo vocal tracks. They achieved this through two years of research, studio recording, and model training.
As you'll see in the demo video above, Synth V Studio 2 Pro comes with a piano roll that maps directly onto each syllable of your lyrics. Users have meticulous control over both the melodies, the annunciation of words and the subtle vocal dynamics like breathiness and volume. A total of six languages are supported, including English, Spanish, Japanese, Korean, Mandarin, and Cantonese.
This second demo showcases the Ace Studio choir feature. I've deeplinked to the middle of the video, so you can see the results of his work. Ace Studio delivers incredible vocal realism and a multitrack DAW for vocal composing and editing. As one would expect, the Ace Studio AI choir sounds distinct from Dreamtonics, because they've trained their own model. Similar pitch-intonation controls are exposed, along with pitch control for each vocal melody. You can read more about the singing voice generator and choir feature on their website.
Controlla: Beginner/Intermediate AI Choir Tool
Controlla XYZ was one of the first AI singing voice generators to hit the market. While their peers focused on celebrity deepfakes and memes, Controlla took a different route and created ethically-trained AI voice models for music creators.
They currently offer two methods of choir generation. The video below showcases their lyrics-to-choir tool. You can watch a quick demo to see how it works, and then we'll get into the voice-to-choir option after that.
Controlla lyrics-to-choir tool turns lyrics them into monophonic vocal stems. It does not generate full polyphonic arrangements, but it does result in a choral vocal timbre. With minimal control over the melody or articulation, this tool is best for sample-based artists who want to chop something up in post production.
Musicians who want more control over the vocal outputs can use the voice-to-choir tool instead. I'll share a quick walkthrough of their interface below, so you can see exactly how it works.
Click on the style sampler tab, select "choir" as shown in the screenshot below:
Click "select audio" and Controlla will present you with three options:
Community Styles - Choose from a variety of choir presets included as part of the service. Each of these AI singers have their own timbre and singing style.
My styles - This is the library of custom styles you've created over time. They are generated whenever you upload reference audio or record directly into your browser.
Upload or Record - This is the main entry point for creating a new style. Upload a wav, mp3 or m4a file to get started.
You'll need to upload an audio file that's at least 15 seconds long in order to generate your own styles. Controlla will pass your lyrics through the voice style of your choice to generate your outputs:
Here's a demo from the company's cofounder Jeff. With this technique, music producers are no longer limited to creating choirs from their own voice or hiring live singers to record the ideas. It becomes easier to achieve a wide range of vocal timbres, in a much shorter period of time.
Step 1: Recording your vocal stems in a DAW
Start by opening your DAW project file and recording up to four layers of low vocals and four layers of high vocals.
The vocal performance on each stem should sound distinct—experiment with different tones and delivery styles to create the illusion of multiple singers. Keep your recordings clean and dry (no reverb or effects), so they’re ready for processing.
Once those are recorded, export each vocal layer individually. Make sure to label them clearly so it's easy to know where they belong in the arrangement. A simple naming convention like "high 1", "high 2" ... "low 5", "low 6" will work. The numbers indicate their track position in the DAW, from top to bottom. This will help the next step go quickly.
Step 2: Using "Swap Voice" to change the timbre
Upload your vocal stems to Controller Voice and navigate to the Swap Voice tab. This is where the magic happens.
Assign different vocal layers to AI-generated voices. For example, swap your high vocals with a female voice like "Lola" and your low vocals with a male voice like "Scott."
Optionally, apply pitch shifting to create additional vocal variation.
Click Swap Voices and let Controller Voice process the transformation.
Once you're satisfied, download the new choral layers and bring them back into your DAW.
Step 3: Mixing and expanding the Choir
Now it’s time to turn those AI-generated vocals into a full, immersive choir.
Panning – Spread the voices across the stereo field for a wider sound. Slightly pan some takes left and others right.
Grouping – Create a summing track (bus) to process all the vocals together.
EQ & Distortion – Roll off unnecessary low frequencies, boost highs for clarity, and add a touch of saturation for warmth.
Compression – Apply light compression to glue the choir together.
Reverb & Space – Use concert hall and church-style reverbs to place the choir in a grand acoustic environment. Layering multiple reverbs can enhance the depth.
After processing, your simple vocal recordings will sound like a full-fledged cinematic choir, ready to be layered into your composition. Add instrumental backing, and you've got an epic choral arrangement, all from your own voice.
Controlla vs Kits AI: Cost, Quality and Flexibility
Controlla's main competitor is Kits.AI. These companies serve a similar entry level to intermediate level music producer, and offer a similar set of features. I've taken a screen capture of both company's pricing pages as of 2026. Compare below:
While Kits AI offers a selection of AI choir voices, Controlla prioritizes quality over quantity. It also differentiates on the number of custom voices you can have.
Monthly Pricing & Cost Efficiency
Controlla (Monthly): $6 / $12 / $30
Kits AI (Monthly): $10 / $30 / $60
Core Product Focus
Controlla: Full AI music creation platform with song generation, voice swaps, stem splitting, style sampling, and voice creation.
Kits AI: Vocal-focused toolset with singing voice synthesis, vocal blending, choir tools; no full song generation.
Voice Models & Training
Controlla: Explicit monthly studio voice model training (1–3 per month depending on tier) + unlimited instant voice cloning.
Kits AI: Voice slots and “professional clone” quality tiers, but no recurring monthly training allowance.
Usage Limits & Scaling Model
Controlla: Credit-based limits tied to concrete outputs (songs, swaps, stem minutes), scaling up to 300 songs/month on Creator plan.
Kits AI: Time-based limits (conversion/download minutes) with “unlimited” minutes reserved for $60 plan.
Professional & Commercial Readiness
Controlla Pro: API access, automation, concurrent jobs, fine-tuning, and royalty-free commercial usage at scale.
Kits AI Pro: High-quality vocals with unlimited downloads, but no API or automation emphasis.
When you take all of the above into consideration, Controlla does seem to come out on top as the more affordable and feature-rich option. I'd still encourage curious producers to compare the vocal timbre for Controlla and Kits, to see which best suits your projects. At the end of the day, sound quality and aesthetic match is the most important thing.
