Offline technology implementation
Real-time speech synthesis is accomplished by downloading speech model packages (300-500MB/language on average) to local storage and utilizing the computing power of the device. Users can completely disable network requests by selecting "Offline Mode" in the settings menu, and all text processing is done in the browser sandbox environment.
Three core advantages
- privacy and security: Sensitive content such as medical literature, confidential information, etc. does not leave the equipment throughout the process
- responsiveness: Eliminate network latency and generate voice in 0.3 seconds on average (lab data)
- <strong]Scene Adaptation: Works well on airplanes, basements, and other network-less environments.
caveat
You need to reserve at least 1GB storage space for the multi-language model. It is recommended to prioritize the download of the English base model (only 220MB) and then add other language packs as needed. Offline mode may affect the real-time update of some advanced features.
