For free AI singing voice generation, start with LyricToMelody AI if you want to turn lyrics into a sung melody, Applio if you want to convert a vocal recording into another voice, or SightSinger if you have a MusicXML score. Those workflows produce different results: a text-to-singing tool drafts a vocal part, while a voice converter needs a source performance to transform. Free access can also mean a limited trial or a plan that lets you generate but not download, so check the row that matches your goal.

Best Free AI Singing Voice Generators
1. LyricToMelody AI — Best For Drafting A Vocal From Lyrics
LyricToMelody AI is the most direct fit when you have words but no singer or melody. It generates melodies and sung vocal drafts from lyrics or MIDI, and its free Starter plan includes 20 starting credits with no card required. Projects on Starter are retained for 7 days. The product describes a web application, so plan to work in a browser rather than a desktop app.

Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsWorkflow: enter a short verse, preview its melody with the AI singing voice, then revise the lyric phrasing or provide MIDI if you already have notes. The free plan is useful for sketching; if you need to keep projects longer or use commercial rights, check the vendor’s current plan terms.
2. Applio — Best Free Voice Conversion Suite
Applio converts real-time or uploaded audio and supports custom voice-model training, blending, batch inference, TTS and CLI automation. Its open-source software is available free for Windows, macOS and Linux, with cloud and self-hosted workflows also described by the project. It is a voice-conversion suite, so bring a sung take when the goal is to hear a performance in another voice; it is not the same lyric-to-melody workflow as a singing synthesizer.

This is score-led singing, not a tool for transforming a recorded singer. Commercial use is described as royalty-free where permitted by the selected voice’s terms, so check those terms before release.

Uberduck offers singing and rapping generation from text, alongside speech generation, and invites users to get started for free. The available information does not specify free-tier limits or establish controls for melody, timing or vocal editing, so check the vendor’s site for what the current free access includes before building a track around it.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How To Choose A Free AI Singing Voice Generator
- Have lyrics but no melody? Choose a lyric-led option such as LyricToMelody AI or Uberduck; check whether the free access includes the controls and exports you need.
- Have a score? SightSinger is the score-to-audio choice here, provided you can supply MusicXML.
- Have a sung recording to transform? Compare Applio, On4t, TopMediai, Kits AI, DDSP-SVC and Audimee. Conversion needs source audio, and these tools differ in setup, free limits and download access.
- Need note-by-note control? The VOCALOID6 and Synthesizer V Studio 2 Pro trials offer desktop synthesis and editing, but neither is a permanent free plan.
For any cover or cloned voice, use only recordings and voices you have permission to use. Check both the platform’s terms and any selected voice or model terms; free access alone does not establish rights to publish a result.
