A.I.VOICE review
A focused Japanese narration tool with detailed voice controls and WAVE export.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
A.I.VOICE is a Japanese text-to-speech software series from AI, Inc. It is designed for users who enter Japanese text, shape the delivery of character and Neural voices, and export synthesized narration. The desktop software supports Windows and Apple-silicon Mac computers, while API and web options extend the product toward external applications and business workflows. Its strongest fit is Japanese character-voice narration where control over delivery matters more than multilingual coverage.
Voice editing goes beyond basic speed adjustment. Users can control speech speed, pitch, intonation and pauses, then refine phrases and words with user dictionaries. Character voice libraries and Neural voice libraries provide the core voice options, while project-file saving and restoration support ongoing work. WAVE audio export gives finished audio a standard output path, and the editor API allows external program control. A.I.VOICE Biz adds a commercial web editor and web API for business applications, making the broader product family more suitable for teams than the individual desktop editions alone.
Pricing is paid rather than free, with a 14-day free trial and a listed starting price of 9680. The A.I.VOICE2 Kakyoyosari download edition includes Japanese character voice synthesis, WAVE export, and Windows and Apple-silicon Mac support. That price applies to a specific voice edition rather than a universal subscription tier. Individual editions are licensed for personal use, so commercial projects should use the applicable A.I.VOICE Biz or commercial license. Choose A.I.VOICE for Japanese narration with character voices, detailed prosody controls and project-based editing; choose an alternative if multilingual support, voice cloning or broader export formats are central requirements.
