For an AI duet, Audimee is the closest match for turning two recorded vocal parts into contrasting voices and building harmonies; VOCALOID6 and Synthesizer V Studio 2 Pro suit duet makers who want to write or edit synthesized vocal parts on a computer. None of the listed tools is established as a one-prompt generator that writes and delivers a finished duet song. Think of them as ways to create or transform the vocal parts: you still need to supply or arrange the song’s lyrics, melody, and accompaniment as each tool allows.
What Makes A Duet Tool Useful?
A duet needs more than two vocal sounds. The singers should have distinct parts, the words should land together where intended, and the arrangement needs room for each voice. Common choices include alternating lines, overlapping replies, singing the same melody together, or splitting into harmony. A tool that makes harmonies may help with one of those jobs, but that does not establish that it can write a complete two-singer song from a prompt.
For a budget-conscious phone user, the main practical question is where the work happens. Audimee is web-based, while Synthesizer V Studio 2 Pro and VOCALOID6 are desktop software for Windows and macOS. The supplied details do not establish that the desktop tools run on Android or iOS, or that any of these tools has a dedicated phone app. Check each vendor’s site for current device requirements before paying.

You can also write a single melody and add a harmony line for the refrain. These are arrangement examples, not claims that any product automatically composes those parts from a prompt.

Best AI Duet Song Generators Ranked
1. Audimee — Best For Turning Two Recorded Parts Into Different Voices
Audimee is the most direct fit when you can record both sides of a duet yourself and want to reshape the vocal sound. It is a web-based vocal converter with voice conversion, pitch editing, isolation, stem splitting, and a harmony maker that supports up to five harmony tracks. Its site also describes mixing voices and converting vocals with royalty-free voices. Those tools give a duet maker several ways to work with separate lead parts or add supporting harmony.
A practical workflow is to record the first singer’s question and the second singer’s reply as separate takes, then use voice conversion to explore contrasting sounds. For a shared refrain, prepare the melody in both parts and use the harmony maker for added layers where they suit the arrangement. Audimee is not documented here as a lyric-and-song prompt generator, so bring your own lyrics, melody, or vocal recordings rather than expecting a finished duet from a text description.
The free option provides an initial 15 minutes of conversions as a one-off introduction; it does not reset. The Starter plan is listed at $9 per month and allows one hour of conversions per month. The tool is limited to the web platform, so check that it works well in your phone’s browser and review the vendor’s current plan details before relying on a mobile workflow. The available details do not establish a dedicated mobile app.

Audimee describes its voices as royalty-free and mentions copyright-free cover vocals, but the information here does not establish the complete rights for every use or every input. Get consent for any real person’s voice you record or convert, and check Audimee’s current terms for the selected voice, covers, and intended release.
2. VOCALOID6 — Best For Arranging Synthesized Duet And Chorus Parts
VOCALOID6 is a desktop singing generator that makes singing from melody and lyrics, and its documented features include instant harmony creation, expression controls, and more than 100 style presets. This makes it a strong option if you want to build a duet arrangement from written or programmed vocal parts, especially where a chorus needs a second line or a fuller sound. It supports singing lyrics in a mixture of Japanese, English, and Chinese with a single voicebank.
For a call-and-response idea, create the first singer’s melody and lyrics, then prepare the answering part as another vocal line in the arrangement. For the refrain, use the harmony feature to develop supporting parts. The product details establish harmony creation, but they do not specify the exact process for assigning two distinct lead voices to simultaneous lines; check the vendor’s workflow and voicebank requirements before buying if that is essential to your duet.
VOCALOID6 is a one-time purchase listed from $225 before tax, with a 31-day trial and no free plan. It runs on Windows and macOS, not as a browser tool. MIDI export is supported, and the product comes bundled with Steinberg Cubase AI. These are desktop-oriented tools and workflows, so check system requirements and current pricing on the vendor’s site before committing from a phone.

3. Synthesizer V Studio 2 Pro — Best For Precise Editing Of Duet Vocal Parts
Synthesizer V Studio 2 Pro is for producers who want detailed control over synthesized singing. You can write vocal melody ideas on a MIDI keyboard or import MIDI, add lyrics, and turn the notes into vocal parts. Its editing controls cover pitch, timing, pronunciation, timbre, and expression. That precision is useful for shaping two duet lines so that syllables, entrances, and held notes fit the arrangement.
Rank #4
One possible workflow is to map the first singer’s melody in MIDI and add its lyrics, then create a separate answering melody for the second part. You can also make choir rehearsal tracks or vocal parts for cover songs by importing vocal melodies as stems or MIDI and changing them into new voices with custom expressions. The product supports cross-lingual synthesis across six languages. However, the listed plan includes one voice of your choice, and the supplied details do not establish that one purchase includes two distinct voices for a duet. Confirm voice availability and licensing with the vendor before planning a two-voice arrangement.
The listed price is $89 as a one-time purchase, and there is a 14-day trial but no perpetual free plan. It is desktop software for Windows and macOS, available as a standalone app and plug-ins. That makes it the least phone-oriented choice in this roundup. A mobile user should check the system requirements and trial the workflow on a compatible computer before buying.

Prices and trial details are those listed in the available product information; vendors may change them. Audimee’s free minutes are a one-off allowance, not a monthly refill. The tools differ in what they make easy: Audimee starts with recorded vocals, while the two desktop products focus on synthesized singing and arranged vocal parts.
Which One Should You Choose?
- Choose Audimee if you have two vocal recordings and want to convert their sound, mix voices, or add harmony through a web tool. Check browser compatibility on your phone first.
- Choose VOCALOID6 if you want desktop singing generation from melodies and lyrics, with harmony creation and style presets for a chorus arrangement.
- Choose Synthesizer V Studio 2 Pro if editing control over the duet’s note timing, pronunciation, pitch, and expression matters more than working from a phone.
Before making a purchase, decide whether you need two distinct lead voices, backing harmonies, or simply a transformed version of your own two takes. Verify that the product and voice choices support that exact setup, then check the vendor’s current platform requirements, plan details, voice rights, and terms for your intended release.
