Privacy first dictation and translation software
Speak naturally. Dictate where you work, or turn your words into another language. Processing stays on your PC.
01 / Find your flow
Click a supported text field. Hold your shortcut keys, speak, then release. Blabbermouth transcribes locally and inserts the text without using your clipboard.
Change the keys or choose press-once toggle mode. Escape cancels.
Keep correction rules, reusable snippets and simple per-app formatting.
Transcribe supported audio and video files locally. Export text or subtitles.
02 / The private route
Speech recognition happens on your computer. The microphone records when you start dictation and stops when you finish or cancel. No recordings or transcriptions are uploaded to the cloud.
03 / Before you begin
Local processing. Practical choices.
Current guidance: x64 Windows 10 build 19041 or later, or Windows 11; 4 logical processors; 8 GB RAM; a microphone; 2 GB free space plus speech models.
A smaller model reduces waiting on modest hardware. The app’s experience indicator estimates suitability from CPU count and RAM; it is not a speed control. GPU support and storage also affect performance.
A dedicated graphics card is optional. For NVIDIA GPU acceleration, a practical starting guide is 2 GB VRAM for Small, 4 GB for Medium, and 8 GB for Large v3. These are suggested card capacities, not minimum requirements; other apps also use GPU memory. Parakeet runs on the CPU.
Start with the Buy now page. Once you have your installer and licence, install Blabbermouth, activate your licence and download a speech model. Then select your microphone.
Activation: General → Licence → Licence key → Activate Blabbermouth.
A licence supports two Windows profiles. Choose General → Licence → Deactivate this installation to free a place. Contact support if you cannot access an old installation. Never email your full Licence Key.
The latest microphone recording stays in memory for retry. You can explicitly save it as a WAV file; it is not written automatically.
English speech to English text, in supported Windows fields. Review important names and numbers. Accuracy varies with your model and recording.
04 / Local translation
Speak English. Write in French, Spanish, German, Italian, Portuguese or Dutch, plus more.
Keep it on your PC. Download a language pack, then translate your dictated words locally.
Into English, too. A compatible multilingual speech model turns supported speech into English text.
