Implementing a "say" command using ISpVoice from the Microsoft Speech API

I’ve known for a while that Microsoft Windows comes with text-to-speech and speech-to-text APIs, which power the Narrator and Speech Recognition features respectively.

This forum post prompted me to mess around with them a little.

I came up with this implementation of a say.exe command which takes a single argument as text, and then uses the ISpVoice text-to-speech API to have the computer speak it aloud.

Source and binaries attached.




>say.exe “Daisy, Daisy; give me your answer, do.”
