For free AI singing voice generation, start with Uberduck for singing from text, Applio for converting an existing vocal, or LyricToMelody AI for turning lyrics or MIDI into a sung draft. These tools solve different musical problems: a text-to-singing generator needs lyrics, a voice converter needs audio, and a score or melody workflow needs written musical input. On a Xiaomi, Redmi or POCO phone, check each vendor’s site for current mobile-browser support before starting; the information available here does not establish that every web tool works well on a phone.
Choose The Singing Workflow That Matches Your Starting Point
- Lyrics or text, no vocal recording: Try a tool that generates singing from text or lyrics, such as Uberduck or LyricToMelody AI.
- An existing vocal you want in another voice: Look at voice-conversion tools such as Applio, Kits AI, On4t AI Voice Cover or DDSP-SVC. These require audio input or a voice model, depending on the workflow.
- Notes, lyrics or a score: LyricToMelody AI supports lyrics or MIDI, VOCALOID6 generates singing from melody and lyrics, and SightSinger converts MusicXML scores into singing audio.
- Your own trained voice: Applio, Kits AI, Humlo and TopMediai AI Song Cover describe custom voice or model training. Check the vendor’s site for the supported recording process and requirements.
Best Free AI Singing Voice Generators
1. Uberduck — Best For Singing From Text
Uberduck is a direct option when you want to generate singing from text rather than first record a vocal: its site describes generating speech, singing and rapping from text, and says you can get started for free. The free-start statement does not specify a credit allowance or other limit, so check the vendor’s site for current access and plan details. For a simple starting workflow, prepare a short lyric passage, select the singing task offered by the service and check the result before building a longer piece. The specific voice choices and editing controls are not established here.

2. LyricToMelody AI — Best For Lyrics Or MIDI To A Vocal Draft
LyricToMelody AI generates melodies and sung vocal drafts from lyrics or MIDI, and lets you preview a melody with an AI singing voice. Its Starter plan provides 20 credits to start, requires no card and retains projects for 7 days; paid plans start at $10 per month when billed annually. It also supports custom singing-voice training from uploaded or recorded vocals and exports MIDI, audio and separate stems. The site describes it as a web application, so check mobile-browser compatibility if you plan to work from your phone.
3. Applio — Best Free Voice Conversion For Technical Users
Applio is a free, open-source voice-conversion suite for making AI covers, training custom voice models and converting voices in real time, on your machine or in the cloud. Its listed platforms include Windows, macOS, Linux, Colab and Kaggle. It can work with uploaded audio and offers model blending, batch inference, exports, text-to-speech and CLI automation. Voice conversion depends on voice models, and the CLI or self-hosting options may suit technical users better than someone looking for a one-tap phone workflow.

4. Kits AI — Best Free Starting Point For Vocal Production
Kits AI combines voice conversion with voice cloning, blending, separation and mastering. Its free plan includes 15 conversion minutes, one voice slot and zero download minutes per month, so free access does not include downloadable minutes under the stated plan details. The site also offers custom AI singing voices. Advanced features are spread across paid tiers, and the strongest cloning tools start with the Starter plan. Artist-model outputs may need approval for commercial release; check the applicable voice and plan terms before publishing.
5. On4t AI Voice Cover — Best For Trying Cover Conversion In A Browser
On4t AI Voice Cover offers free browser-based voice conversion, downloadable generated audio, voice previews, and language, emotion and pitch controls. It accepts uploaded audio and YouTube URLs. The listed language choices are English, Arabic, Brazilian Portuguese, Chinese, Dutch, French, Hindi, Hungarian, Italian, Japanese, Korean, Polish, Russian and Turkish. The free version has options for more features at a premium, but a specific free usage limit is not stated here. Its workflow centers on uploads and YouTube links, so check the site for current input rules and availability.
6. TopMediai AI Song Cover — Best For Cover Experiments With A Custom Voice
TopMediai AI Song Cover describes itself as a free AI song-cover generator and supports generating covers with custom voice models. Its custom training feature accepts raw recordings, and the service lists MP3, WAV and M4A files or YouTube links as inputs. The free claim does not establish a usage allowance, download limit or commercial-use terms. Check those details on the vendor’s site before relying on it for a complete song or release.

7. SightSinger — Best Free Option For Choir Parts From A Score
SightSinger converts MusicXML scores into AI singing audio and can split SATB parts with verse and part selection. Its free plan provides 8 credits that reset monthly, described as about 4 minutes of audio or about one full song per month. It supports Mandarin Chinese, Cantonese Chinese, Japanese, Thai, English, Spanish, French, Italian, Portuguese and European Portuguese. It has no voice cloning, vocal input or stem export, so it is a score-to-vocal tool rather than a converter for a recorded lead voice. Commercial use is permitted where allowed by the selected voice’s terms.
8. VOCALOID6 — Best Free Trial For Melody-Led Singing
VOCALOID6 generates singing from melody and lyrics, with VOCALOID:AI for natural-sounding, expressive voices. A single voicebank can sing lyrics mixing Japanese, English and Chinese. The product has a 31-day free trial, but no free plan; the listed one-time price is $225 before tax. It is a Windows and macOS desktop application, not a phone-based browser generator. Its vocal-style replication, harmony creation and expression controls give a producer more to shape than a quick cover conversion.
9. UtaiSynthesizer — Best Free Local Workstation For Windows
UtaiSynthesizer is a free, open-source Windows workstation for covers, voice conversion and vocal synthesis. It combines separation, RVC, SoVITS, synthesis and model training, with node workflows and multitrack timeline editing. It can export WAV, FLAC, MP3, OGG, OPUS and M4A. Processing happens through local workflows that require managing models and on-device processing; some model weights restrict commercial use. This is a desktop option, not a singing generator to run directly on a Xiaomi, Redmi or POCO phone.

10. DDSP-SVC — Best Free Open-Source Singing Voice Conversion Project
DDSP-SVC is an open-source project for free singing voice conversion software intended for personal computers. Its project description says its training and synthesis hardware requirements are lower than those of SO-VITS-SVC, with training time closer to RVC; this is a project comparison, not a guarantee for every device or setup. The project specifically asks users to train models only with legally obtained, authorized data. The available information does not establish a simple phone app, so check its documentation and setup requirements before choosing it.
11. Humlo — Best For Training A Personal Voice On iPhone
Humlo says it can train a personal AI voice model from 30 seconds of singing, ready to sing on a track. Its stated platform is iPhone with iOS 16 or later, making it the clearest phone-oriented option in this roundup for Xiaomi, Redmi and POCO readers who also have access to an iPhone. Android availability, free-plan limits and commercial-use terms are not established here; check the vendor’s site for those specifics.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Consent, Downloads And Use Rights
Before using a real person’s voice, get their consent and check the service’s terms for voice models, covers, generated audio and publication. Product terms vary: Applio says it can be used, modified and redistributed for personal projects, research or commercial work, while that statement does not grant rights to any voice data used with it. Uberduck says commercial use is available on any paid plan. SightSinger’s commercial-use permission depends on the selected voice’s terms. Kits AI notes that artist-model outputs may need approval for commercial release, and UtaiSynthesizer says commercial use is restricted for some model weights. For other listed tools, commercial terms are not established here; check each vendor’s current terms before sharing or monetizing a result.
Quick Recap
What To Check Before Starting On Your Phone
- Input type: Match the tool to what you have ready: text, lyrics, MIDI, MusicXML, an audio recording or a YouTube URL.
- Free access: A free start can mean a trial, credits, conversion minutes or an unspecified free option. Check the vendor’s current limits and whether downloads are included.
- Phone support: Only Humlo’s listed platform is specifically iPhone; Applio lists several computing environments, while some other products are described as web or desktop tools. Android support is not established for most entries, so verify it directly.
- Voice and release terms: Check the rules for the voice model you choose, the audio you upload and any commercial use you plan.
