For free AI singing voice generation, start with LyricToMelody AI if you want to turn lyrics into a sung draft, Applio if you want free voice conversion and can manage models, or SightSinger if you are working from a choir score. These solve different tasks: generating a vocal from lyrics or notation is not the same as converting an existing performance into another voice.

Best Free AI Singing Voice Generators
1. LyricToMelody AI — Best For Turning Lyrics Into A Vocal Draft
LyricToMelody AI generates melodies and sung vocal drafts from lyrics or MIDI, and can preview a melody with an AI singing voice. Its Starter plan offers 20 credits to start, requires no card, and retains projects for 7 days. Audio, MIDI, and separate stem exports make it relevant when a filmmaker or creator needs material to continue shaping in a DAW. It is a web application. The supplied details do not specify how many complete songs the starter credits make, so check the site before planning a session. Commercial rights are included on paid plans; check the vendor’s terms for free-plan use and confirm you have permission for any voice material you provide.
2. Applio — Best Free Option For Voice Conversion
Applio is a free, open-source voice conversion suite for uploaded audio and real-time conversion, with custom model training and blending. It runs on Windows, macOS, Linux, Colab, and Kaggle. It can create AI covers, but the workflow depends on voice models; it is a conversion path, not evidence of lyric-to-singing generation. The project says Applio can be used, modified, and redistributed for personal, research, or commercial work. That statement concerns Applio itself; get consent for the voice recordings and check the model’s own terms before making or publishing a cover.

SightSinger converts MusicXML scores into singing audio and can split SATB parts, with verse and part selection, multitrack playback, and mixed-audio export. The free plan resets 8 credits each month, described as about 4 minutes of audio or one full song monthly. Its listed supported languages include English, Mandarin Chinese, Cantonese Chinese, Japanese, Thai, Spanish, French, Italian, Portuguese, and European Portuguese. It does not clone voices or accept vocal input, so choose it for score-to-vocal work rather than transforming a singer’s recording. Commercial use depends on the selected voice’s terms; check those terms before release.
#1 Best Overall
- 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.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.

4. Kits AI — Best Free Trial For Vocal Conversion
Kits AI combines voice cloning and conversion with blending, separation, and mastering, and is available on the web, Windows, and through an API. Its free plan lists 15 conversion minutes per month, one voice slot, and zero download minutes. That last limit matters: free access may let you explore conversion, but the stated allowance does not include downloading converted audio. The strongest cloning tools start on a paid tier, and artist-model outputs may need approval for commercial release. The site describes its custom voices as royalty-free, but that does not settle permission to clone a real person’s voice; check model and platform terms and get consent.
5. UtaiSynthesizer — Best Local Windows Workstation
UtaiSynthesizer is a free, open-source Windows workstation for covers, voice conversion, and vocal synthesis. Its workflow combines separation, RVC, SoVITS, synthesis, and model training, with node workflows, a multitrack timeline, and WAV, FLAC, MP3, OGG, OPUS, and M4A export. The project describes a dual backend, using RVC for speed and SoVITS for quality, plus shallow diffusion and voice blending. This is a substantial local workflow, so expect to manage models and processing on-device. Commercial use is restricted for some model weights; check each model’s terms and use authorized voice data.
Rank #2

6. Uberduck — Best For Singing Directly From Text
Uberduck offers speech, singing, and rapping generation from text and invites users to get started for free. The supplied information does not establish a free-plan quota, supported languages, or a specific singing-editing workflow, so verify those details on the service before building a production around it. Commercial use is stated for paid plans. For any voice resembling an identifiable person, confirm consent and check the platform’s terms.
7. DDSP-SVC — Best Open-Source Singing Conversion Project
DDSP-SVC is an open-source singing voice conversion project intended as free voice-changer software for personal computers. Its project description says training and synthesis have lower hardware requirements than SO-VITS-SVC and training can be much faster. Those are project claims, not a guarantee for a particular computer or recording. The project specifically says to train models only with legally obtained, authorized data. Check the project documentation and model terms for the setup and permitted uses that apply to your work.

The supplied details do not establish a free plan, price, export options, language support, or commercial-use terms; check the vendor’s current offering before choosing it for a production.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Match The Tool To The Material You Have
If you have lyrics but no melody, begin with LyricToMelody AI; if you have notation, export or prepare it as MusicXML for SightSinger. For an already recorded guide vocal or cover, look at conversion tools such as Applio, Kits AI, UtaiSynthesizer, DDSP-SVC, On4t, or TopMediai. For detailed edits to an already synthesized line, consider the Synthesizer V Studio 2 Pro trial. These workflows are not interchangeable: a tool that converts a vocal does not establish that it can compose a new melody from text.
Recommended Free Tools
Try A Short Singing Workflow Before Committing
- Write a short lyric passage and mark the intended syllable stresses, or prepare a short melody as MIDI if the tool accepts it.
- Choose a tool whose stated input matches your material: lyrics or MIDI for LyricToMelody AI, MusicXML for SightSinger, or an existing vocal recording for voice-conversion tools.
- Use a voice you own or have permission to use. For a custom model, confirm the source recording and model are authorized.
- Render a short passage, then listen for intelligible words, timing against the beat, and whether the vocal sits in the intended register. If the service does not document a control you need, check its vendor site rather than assuming it is available.
- Before exporting or publishing, check the applicable free-plan limits, voice terms, and commercial-use rules. A free generator listing does not by itself establish that a particular generated voice or cover can be released commercially.
Consent And Release Terms
Get permission before training on or converting another person’s identifiable voice, and use authorized recordings and model weights. Commercial permission varies: LyricToMelody AI states commercial rights are included on paid plans, SightSinger ties commercial use to the selected voice’s terms, Uberduck specifies commercial use on paid plans, and UtaiSynthesizer restricts commercial use for some model weights. For tools whose supplied details do not establish release rights, check the vendor’s current terms before publishing.
