Bring Your Own Key

When you use your own Azure Speech API key with our app, you unlock the full power of Microsoft’s Text-to-Speech engine — without paying any subscription to us. Microsoft provides up to 11 hours of free speech generation per month under their Standard pricing tier, which is more than enough for most creators, educators, or professionals.

By using your own Azure key, you get total transparency and control. You are directly connected to Microsoft’s servers, and all billing, usage tracking, and limits are managed by your own Azure account. This means:

✅ No hidden fees
✅ No third-party usage tracking
✅ You’re always in control of your quota

Our app simply acts as a user-friendly bridge — it connects your text input with Azure’s powerful TTS engine, letting you choose voices, apply SSML tags, and generate speech without needing to code or deal with Azure's complex interface.

Setup takes just a few minutes. We guide you step-by-step to:

Create a free Azure account (if you don’t have one)
Generate a Speech resource
Paste your key and region into the app
That’s it! From there, you can immediately start generating speech using over 500+ natural voices in 100+ languages and dialects.

Your key stays private — it’s stored locally on your machine and never sent to our servers. You get maximum privacy, and you don’t rely on any middleman services. Just the raw power of Azure, used through a beautifully simple Windows interface.                                                                                                                                                                                                                                                          Want to know how Azure key works ?
