Is speech to text possible?

What are some good open source, command line text to speech synthesizers?

• I want to give the command line a few sentences or paragraphs of text and have it give me natural-sounding speech in mp3 or other widely usable formats. **text to speech** not speech to text. At the moment, don't care at all about being able to go from speech to text.
