eSpeak with Windows 10

Key considerations:

• Duddington's eSpeak materials include an sSpeak program that runs nicely on Windows 10, but
• Windows 10 does not have PortAudio installed by default

Consequences

• Creating a pipe and a new process largely follows a different model on Windows 10 from what is used on Linux or Mac OS X
  • The popen statement of Linux/Mac OS X must be replaced by about 58 lines for Windows 10.
    • Allows considerable control
    • Many standard steps must be written explicitly
  • Otherwise, processing eSpeak commands similar to approach for Mac OS X
    • Change of voice sound (e.g., changing gender) requires killing old eSpeak program and starting a new one
    • For initialization or change of gender, work with eSpeak program
    • Starting of program includes both program name and voice parameters
    • eSpeakTalk involves passing text through pipe
    • eSpeakDisconnect or change of gender requires killing old eSpeak process
