Is there an open source alternative for Nuance Dragon Naturally Speaking?

Fred G June 20, 2013

I’m looking for an open source alternative for Nuance Dragon Naturally Speaking. Yes, I know I can Google it, I have but I’m not coming up with anything useful; might be the search terms I am using.

With the increase in smartphone apps, I thought there would be a ton of PC options out there, but I can only find one.

Thanks in advance.

    Open Source Freeware Solution -> Simon Speech Recognition :

    Also try the built-in feature of Windows :

    Have you tried the built-in speech recognition in Windows Accessibility? You can also make your Windows system look and behave similarly to Jarvis from Iron Man: Other than these, there are few findable options for a free and open-source alternative to Dragon Naturally Speaking.

      Yes I have, might be the way I speak but had a really low correct rate, like only 2 words in a sentence.

    In Linux, there are two options: CMU Sphinx and Julius; however, both options are for users with quite a bit of experience with Linux and can be problematic to piece together. If you’re interested, here are more details:

    CMU Sphinx is a collection of tools for people who work with speech recognition. It’s written entirely in Java, so the installation might be a challenge.

    Julius is an open source large vocabulary CSR engine. Make sure you spend some time on the website — you might find that Julius is just what you need.

      Thanks for the link, there is a very good line in that article:
      "Keep in mind there’s a reason why Dragon NaturallySpeaking is so popular, as well as pricey — it works."

      Probably why I am having problems with other options.

    Similar questions have been asked many times before, although I don't remember anyone ever asking specifically for an open source alternative.
