Principles of technical implementation of vosk-browser
vosk-browser is an innovative speech recognition tool that uses WebAssembly technology at its core to realize real-time speech processing on the browser side. WebAssembly, as a low-level assembly-like language, can achieve near-native performance in modern browsers. The tool compiles the Vosk speech recognition library into a WebAssembly module, allowing complex speech recognition algorithms that would otherwise require server support to be executed directly in the browser sandbox environment.
- The key technology stack includes: WebAssembly to provide computational power, Web Audio API to handle audio streaming, and WebWorker to enable multithreaded parallel processing
- The binary model files are stored in a compressed format with an average size of about 50MB.
- Speech feature extraction using MFCC (Mel Frequency Cepstrum Coefficient) algorithm, supports high precision version mfcc_hires.conf configuration
This architectural design effectively solves the bottleneck problem that traditional speech recognition solutions must rely on cloud-based services.
