For an AI duet, the strongest documented options here are VOCALOID6 for generating a lead and harmony, Audimee for building harmonies from recorded vocals and mixing voices, and Synthesizer V Studio 2 Pro for detailed editing of two synthesized parts. None of the available product details confirms a dedicated “duet” button or a complete duet-song generator, so treat these as ways to make duet vocals—not proof that a tool will generate a finished two-singer song from one prompt.
A convincing duet needs more than two vocal sounds. The parts should have distinct roles, enter and leave at intentional moments, and fit together in pitch, timing and expression. One singer might carry the verse while another answers, then both join for a chorus. The options below suit different ways of building that arrangement; the amount of control over lyrics, voices and the backing track varies.

“Not stated” applies to whether any of these can generate a complete duet song from a text prompt, and to a dedicated duet mode. Their documented features support vocal-part creation or processing, but don’t establish automatic writing of a full song, a backing arrangement, or a conversational exchange between two singers. Check each vendor’s site for the current product details before choosing.
Ranked AI Duet Song Generators
1. VOCALOID6 — Best For Generating Lead And Harmony Parts
VOCALOID6 is the most direct fit when your duet starts with lyrics and a melody you can arrange. Its documented capabilities include generating singing from melody and lyrics, instantly creating harmony parts, and more than 100 style presets for changing the manner and tone of a voice. That gives a songwriter a clear route to a duet-shaped arrangement: establish the lead, add a contrasting harmony or chorus line, then adjust their roles and expression.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

For example, prepare a verse melody for one singer, then write a second line that answers the last phrase rather than singing over it. For the chorus, add harmony where the lines should overlap. This is a practical arrangement example, not a claim that the software writes those parts automatically. The source material establishes harmony creation, but doesn’t specify an automatic call-and-response writer or a prompt that generates lyrics, melody and backing together.
Language matters if the duet crosses languages: one voicebank can sing lyrics mixing Japanese, English and Chinese. The product is a paid Windows and macOS desktop tool, with a listed price from $225 as a one-time purchase and a 31-day trial. A free plan is not listed. VOCALOID6 includes Cubase AI and supports MIDI export, which can help if your workflow involves arranging or moving musical parts between compatible tools.

2. Audimee — Best For Layering Harmony Onto Recorded Vocals

Its site describes converting raw recordings with royalty-free voices, training your own voices, and creating cover vocals. Those capabilities make it relevant when you can record a lead and want to build a layered duet-like sound around it.

A concrete workflow is to record the lead phrase, decide where a second part should answer or overlap it, then use the harmony tools to make supporting lines. Keep the verse sparse if you want the response to stand out; reserve stacked harmony for a chorus. These are arrangement choices for the user. The listed feature is a harmony maker, and the available details don’t say that Audimee will independently compose a second singer’s lyrics, generate a complete song, or assign two characters to trade lines from a text prompt.
Audimee has a free plan with 15 minutes of conversions as a one-off introduction; the limit does not reset. Its paid pricing starts at $9 per month. Starter and Pro plans cap monthly conversion time, while Ultimate includes unlimited monthly conversions and eight voice slots. Check the vendor’s current pricing page for the exact limits and terms of each paid plan. The tool is limited to the web platform.

Before using a converted voice in a release, check Audimee’s current terms for the selected voice and intended use. The product listing describes royalty-free voices and copyright-free cover vocals, but that wording alone doesn’t establish the terms for every voice, input recording or release. Get consent for any person whose voice you record or train a custom model from.

For a verse exchange, create the first singer’s MIDI melody and lyrics, then prepare a separate answer line for the other part. Shape their timing and expression so one voice can finish before the other enters. For the chorus, arrange any overlap in the musical parts yourself. The documented editing controls provide ways to refine the parts, but the available information does not confirm an automatic duet arrangement feature or a one-prompt finished song generator.
The product supports cross-lingual synthesis across six languages and works as a standalone Windows or macOS desktop app, with VST3, AU, AAX and ARA plug-ins. It costs $89 one time and has a 14-day trial; there is no perpetual free plan. One purchase includes one voice of your choice. Voice cloning is not provided. Check Dreamtonics’ site for the available voice choices, licensing terms and details relevant to a release.
This is the most editing-oriented choice in this group. It fits a producer who can supply the duet’s melody and lyrics and wants fine control over each synthesized performance, rather than someone looking for a browser prompt that completes a whole song.
How To Choose A Tool For Your Duet
Start by deciding what you already have. If you have lyrics and can compose both melodies, compare VOCALOID6’s harmony creation with Synthesizer V’s detailed part editing. If you have a recorded lead vocal and want to add harmonies or change its voice, Audimee is the option here with documented conversion and harmony tools. These workflows depend on the stated product capabilities; none establishes that a finished song can be generated from a text prompt alone.
- Plan the exchange. Mark which singer leads each verse, where the other answers, and which chorus phrases overlap. A duet needs clear entrances and complementary lines, even when the software supplies the singing.
- Decide whether the parts are written or recorded. Melody-and-lyrics workflows point toward VOCALOID6 or Synthesizer V. A recorded-vocal workflow points toward Audimee.
- Check the voices and language first. The documented language support differs, and voice availability can depend on the product and plan. Verify the exact voice, language and singing style you need with the vendor; do not assume that a tool supports a particular genre or singer identity.
- Read terms for the intended release. Confirm how the platform treats the chosen voice and your recording, cover or commercial use. Get consent before using a real person’s voice or training a model from it.
For duet production, the practical dividing line is whether you want to compose and edit two sung parts or convert and layer recorded vocals. These three tools document support for parts of those workflows. The available product details do not establish a complete, prompt-to-song AI duet generator, so check the vendor site before buying if automatic duet songwriting is essential.
