wav file with the generated audio to the emulated filesystem. The result of running the compiled eSpeak code is that it ‘writes’ a. This allows the normal eSpeak datafiles to be used (either through an xhr, or by converting them to JSON and bundling them with the script file). Once compiled, the eSpeak code in speak.js doesn’t know it’s running on the web: speak.js uses the Emscripten emulated filesystem to ‘fake’ the normal file reading and writing calls that the eSpeak C++ code has (fopen, fread, etc.). speak.js is a port of eSpeak, an open source speech synthesizer, from C++ to JavaScript using Emscripten.Ĭompiling an existing speech synthesis engine to JavaScript is a good way to avoid writing a complicated project like eSpeak from scratch.
