Text-to-speech & AI dubbing for 80+ languages. No subscription.
I'm excited to share Kaizen Speech Studio - a Windows desktop app that makes professional speech and audio work accessible to everyone.
The Problem We're Solving
Most speech services lock you into expensive monthly subscriptions ($20-50/month). You're limited by time restrictions, usage caps, and high costs. Plus, you need internet for everything and lose access if you stop paying.
What Kaizen Does

Write anything in any language → Get natural-sounding audio
600+ professional voices across 80+ languages
Control pitch, speed, volume, and emotion (happy, sad, professional, cheerful, etc.)
No time limits - create 1-hour audiobooks easily
Import PDF, DOC, or TEXT files directly
2. Speech to Text
Speak into your mic → Get accurate text transcription
Upload audio files for conversion
Supports 80+ languages with local accents
Record while transcribing for dual output
3. AI Video Dubbing

Optional subtitle addition
