Speech!

[Dekudude]

Hi there!

I'm working on a simple script, and I was wondering if there is some way to use the Microsoft built-in speech SDKs (to voice, and text FROM voice)? I'd like to capture raw_input() data from my microphone whenever the program recognizes that something went through the microphone. I'd also like to have the program use the default text-to-voice synthesizer I have installed... currently Microsoft Mary.

Is this possible? If so, how might I go about doing it? Are there any simple modules with functions such as, "say()" or "listen()"? Thanks a lot!

Hmm, okay. I figured out text to voice. Is there some way to do voice to text, though? I already have the Microsoft speech API, SAPI, but I don't know how to make that work with Python...

Thanks for your response:

However, that is not exactly what I want. For starters, I already got the text-to-voice working. As for voice-to-text, I already tried that example, but it doesn't work how I want it to. As far as my beginner eyes can see, there's no way to replicate raw_input() using it, where if I said, "This is a test, hello world", it would enter that.

Do you understand what I'm saying? If you can show me how to use that code example, that would be great, but I just want a raw_input() style function that enters data via voice-to-text.

Thanks!
