Hello Everyone. I'm new to python and so far, I simply love it! I'm still just starting to get the knack though and there's a lot more I want to know. I've decided to use it mainly for my robots' programming scripts. Right now I'm currently stuck on a simple script on getting my windows vista machine to recognize phrases I say, and reply to them using TTS. It's a learning process in itself.
Bare with me, most of the time I feel like I haven't got a clue when I'm writing a python script. It's the first programming language I'm learning.
Here's the script I'm using on my computer. I'll implement it into my robot later, once I get it to work. I modified it from two python sample scripts by Inigo Surguy and Peter Parente, so a lot of credit goes to them, at least until I become savy enough to write my original speech Recognition and TTS scripts... What I want it to do is wait for me to say "Hello, Aelita" which is what I call my laptop, and respond by addressing my name and asking how I am doing. I'm also trying to get it to tell me the time, whenever I say "Time." It is as follows:

It's working mostly, in that it opens up Microsoft Speech Recognition and recognizes the words I say, and as far as I know the script is free from syntax errors and exceptions. The problem I'm having now is getting the computer's voice to say something back. As of now, the phrase just shows up in the MSR window but doesn't say anything back. I think it has to do with the "speechReco" I write for when the computer's supposed to catch a certain phrase. I don't think its the right term. So, the MSR is recognizing my words, but the python script doesn't, hence no TTS response. I'd appreciate it if maybe someone could help me out with this script, and/or tell me if there's some sort of python syntax dictionary or glossary out there, that tells all the different words you can right in a python script, when to use them, and what they do?
Once again, bare with me. I'm trying to learn as much as I can about this stuff. Thanks.
