VoiSona Song

VoiSona Song is AI singing-voice software for composing and shaping synthesized vocal parts. It is best suited to producers who want control over lyrics, phrasing, and vocal character in a desktop or iOS workflow. Its free editor is useful for a short preview, but full-length singing requires a voice library.

Overview

VoiSona turns notes and lyrics into synthesized singing. You can write a part in its piano roll, import MIDI into a DAW, or upload MusicXML, so it can fit both an in-editor composition process and an arrangement that already exists. This flexibility is valuable for building a vocal line around music you have written; it is less suited to someone seeking a finished song from a brief prompt.

After entering a part, controls for phoneme timing, pitch, volume, vibrato, voice quality, and huskiness let you work on both pronunciation and performance character. Commercial use is allowed. An account is required, and an internet connection is needed for installation and some features.

Key features

The editing controls give producers meaningful ways to refine a synthesized performance rather than simply accept a default rendering. Exports include WAV, MIDI, MusicXML, CCS, CCST, tsmsln, tssprj, and Lab, supporting both audio output and continued work with compatible project formats.

The PC app can run standalone or as a VSTi or Audio Units plug-in. The iOS and iPadOS app also runs standalone, or as an AUv3 plug-in compatible with GarageBand, Logic Pro, Cubasis, and more. That makes VoiSona a practical option for users who want to work within a DAW on desktop or mobile. CeVIO Creative Studio and CeVIO AI exclusive voice libraries are not compatible, so existing owners of those libraries will need another route for those singers.

Pricing

The VoiSona editor is free, but its free tier can make voices sing only the first 10 seconds of a song before a voice library purchase. That cap makes it suitable for previewing a singer or trying the workflow, not for completing full-length vocals on the free editor alone.

The Chis-A voice library is also free and is the default singer available to everyone. Paid song voice libraries have monthly, annual, and outright purchase options; prices vary by library and are displayed in yen. Choose among those options based on the singer you need and whether you prefer a recurring subscription or an outright purchase. Completed purchases cannot be refunded, though automatic subscription renewal can be cancelled during the subscription period.

Platforms

VoiSona Song supports Windows, macOS, and iOS. The PC download supports Windows 10 64-bit version 22H2 or later and Windows 11, or macOS Big Sur 11 through Tahoe 26; it requires at least 4 GB RAM and 1 GB of free disk space. The iOS/iPadOS app adds standalone and AUv3 use, while the desktop app offers standalone, VSTi, and Audio Units modes.

Who it's for

VoiSona Song suits composers and producers who can supply notes and lyrics and want detailed control over the resulting vocal. It is particularly compelling for DAW users who value MIDI or MusicXML input and plug-in integration, as well as iPad musicians working in supported AUv3 hosts. The free Chis-A library provides a no-cost starting singer, but users who need another voice or full-length output should budget for a paid library.

It is a weaker fit for people who need CeVIO-exclusive voices, do not want to create or import a vocal score, or need a free editor without the 10-second limit. Techno-Speech, Inc., the maker, is based in Nagoya, Japan; its support requests go through an inquiry form, with support hours from 10:00 AM to 5:00 PM, excluding weekends and public holidays.

Pros and cons

Pros

• Multiple score-entry routes, including piano roll, MIDI, and MusicXML, suit both direct composition and established DAW projects.
• Phoneme, pitch, volume, vibrato, voice-quality, and huskiness controls allow detailed performance shaping.
• Standalone and plug-in modes on desktop and iOS support several music-production workflows.
• Commercial use is allowed, and the default Chis-A singer is free.

Cons

• The free editor is limited to the first 10 seconds of a song, so full-length work requires a voice library purchase.
• Paid library prices vary, and completed purchases cannot be refunded.
• CeVIO Creative Studio and CeVIO AI exclusive libraries cannot be used.
• Sign-up is required, and installation and some features need an internet connection.

Alternatives

• Revocalize AI is worth considering if you want a freemium option spanning web, mobile, desktop, and other platforms; its free plan includes five conversion minutes per month and one Starter AI voice.
• NEUTRINO is a free alternative for general music and audio production, though system integration or use of generated audio inside an application requires separate permission.
• SoulX-Singer may suit researchers and developers who want free code and model weights under the Apache 2.0 license.
• Kits AI offers a free plan with 15 conversion minutes, voice designer/blender, and generative vocals, making it an option for users focused on those capabilities.
• Audimee may fit web users who want a free plan with 15 minutes of conversions and 11 royalty-free voices, while accepting MP3-only downloads and personal-use-only terms.
• LyricToMelody AI is a web-based alternative for lyric-first draft generation, with 20 starting credits and MP3, WAV, and PCM export on its free Starter plan.

• SightSinger is another freemium singing-voice option to compare.

Verdict

Choose VoiSona Song if you compose vocal parts from scores and want granular performance controls alongside desktop or iOS DAW integration. Its free editor and Chis-A singer lower the barrier to trying it, but the 10-second cap and library costs are the decisive reasons to look elsewhere if you need unrestricted free output or a specific CeVIO-exclusive voice.
