About Browser TTS
Overview What is Browser TTS?
AI speech synthesis running entirely on your device.
View details
Browser-based text-to-speech uses AI models running in the browser via WebGPU to synthesize natural-sounding speech from text input. Unlike cloud TTS services, the inference happens entirely on your device.
Modern browser APIs like WebGPU provide GPU acceleration that makes running reasonably-sized neural network models practical directly in the browser. Combined with ONNX Runtime Web, AI models can generate speech without any server-side processing.
Privacy 100% Private
No server uploads.
View details
Text and audio never leave your device. Since inference happens locally via WebGPU, your voice samples and scripts remain completely private.
Cost Free to use
No API costs or subscriptions.
View details
Because you are providing the compute power using your own device's GPU, there are no recurring server costs. Generate as much speech as your device allows.
Offline Offline Capable
Works without internet.
View details
After the initial model download (which is cached in your browser), the text-to-speech generation works completely offline.
Features Voice Cloning
Clone speaking styles locally.
View details
You can provide a short voice sample (5-10 seconds) to clone the speaking style for your new text, all processed locally within the browser.
