    Ivona and eSpeak aren’t speech recognition, however, I’m glad you told me about Ivona, I’m excited to get the new Kendra voice, it’s the best one I’ve heard, better then the AT&T ones.

    I just want to be able to speak and have my words entered into Word (2007) without typing. My last computer had Vista (hated it!) and so the speech recognition was built in. Not so with Word 2007. Does anyone have a suggestion for a good program for me?

    I need a speech recognition software for my project. Let me briefly describe the project(game development) i am doing. So when someone pronounce the word, we will capture the voice and do comparison to make sure that they pronounce correctly. I chosen Cmusphinx which i feel that it fit my requirement the most as other software deal mainly like text-to-speech. Anyone have any suggestion of software i can use for the project. Thank you in advance

    You might be interested in something like which is free and seems to be based on Google recognition. TalkTyper only works with Chrome, but it seems pretty good if your mic is okay.
