Building from source

This is for Googlers only.

Visit http://go/chrome-tts-blaze for instructions on how to build the engine from source and get the latest voice files.

Google TTS engine is used for the following extension: US English Female Text-to-speech (by Google), and to the best of my awareness, Google voices in window.speechSynthesis.getVoices() on Chrome.
Describe the solution you'd like
Kindly release the complete source code of Google TTS source code. From my understanding it is PATTS, compiled as Native Client binary code in tts_service_<x86_64,x86_32,arm>.nexe.

Describe alternatives you've considered

• How to extract source code from Native Client .nexe file, migrate to WebAssembly? WebAssembly/wabt#1864
• $ wget https://chromium.googlesource.com/chromiumos/platform/assets/+archive/master/speech_synthesis/patts.tar.gz
• Reverse engineering tts_service_<x86_64,x86_32,arm>.nexe.
