VOICEROID review
A Windows tool for Japanese speech editing, with multi-voice controls in VOICEROID2.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
VOICEROID is a paid Windows text-to-speech series from AHS Co., Ltd., using speech-synthesis technology developed by AI, Inc. It is aimed at individual creators who want to enter Japanese text, generate speech and adjust how it sounds. The series includes VOICEROID+ EX and VOICEROID2 for selected voices; VOICEROID2 adds an independent editor and multi-voice support. Its focus is voice editing on a Windows desktop rather than a general-purpose, multilingual speech service, making it a fit for creators working specifically with Japanese audio.
Editing controls are a central strength. Users can adjust volume, speed, pitch, intonation and pauses, while VOICEROID2 adds emotion and style parameters, voice presets and assignment of different voices sentence by sentence. Dictionary editing supports pronunciation adjustments, and split-file saving and WAV export provide options for handling generated audio. These capabilities suit projects that need more than a single pass of text-to-speech, particularly where voice choice and delivery vary within a script. The published export formats include WAV and TEXT; there is no API access or voice cloning, so teams seeking programmable generation or custom cloned voices should consider another product.
The plans are paid downloads, with VOICEROID+ EX and VOICEROID2 available for selected voices. The listed starting price is 8778, while prices vary by character and edition. Commercial distribution requires a separate personal or corporate license, and some characters have restrictions, so buyers planning to publish or distribute work commercially should check the license applicable to their chosen voice. With Japanese as its single supported language and Windows as its platform, VOICEROID is best suited to individual creators who want detailed Japanese voice editing on a desktop; it is not a match for multilingual workflows or software integrations.
