问题
I'd like to build an app that uses voice recognition. I've seen big companies like Google etc implement this feature, but I'm curious about doing it on a start-up level. Anyone looked into this? Are there any tools out there for us to do this?

OpenEars looks promising... http://www.politepix.com/openears/
Based on Pocket Sphinx.

If you start here at wikipedia, you'll get a good list engines (http://en.wikipedia.org/wiki/Speech_recognition#Commercial_software.2Fmiddleware)
As I write this (June 24, 2009) it looks to me that are two viable open source solutions
- Pocket Sphinx (http://www.speech.cs.cmu.edu/pocketsphinx)
- Julius (http://en.wikipedia.org/wiki/Julius_(software))
Both have been used in iphone apps, but the iphone friendly source isn't readily available.
As I edit this (8 July, 2009) I recently learned that Loquendo (http://www.loquendo.com/en/) has voice recognition and speech synthesis (ASR & TTS) for the iphone.

The best approach will probably be to:
- Record the voice on the phone
- Send the recording to a server that runs the speech recognition software
- Then return something to the phone to indicate what it should do

The Dragon Mobile SDK from Nuance does what is asked for. You need an internet connection to be able to send the audio to Nuance's server and you get a list of text responses. You can then decide what to do with the text responses (e.g. ask your user to choose the one he meant or perform some action). Here is the link:
