Voice Recognition / Speech Recognition and speech for the iPhone

08 September

Read more about OpenEars and download the OpenEars library for free!

I’m happy to announce that OpenEars is launched! OpenEars is an open-source iOS library for implementing continuous, multithreaded, and low-overhead speech recognition and text-to-speech, using CMU Pocketsphinx and CMU Flite, for the iPhone and iPad. It uses nice Cocoa-standard cross-project-referenced static libraries and it offers all the easy-to-use Objective-C methods you’ll need to bring round-trip speech functions to your app. The launch version is 0.9.0 and I hope that there will be some cool projects using it.

    Halle – this is awesome. Plan to start working with this over the next couple of weeks. Does it work with other languages besides English? Would it be a major undertaking for me to extend it to spanish? thanks!

    Hi Jake,

    Thanks! Let me know how it works for you.

    I think it might not be too big of a deal to get OpenEars working with Spanish, with the caveat that I haven’t attempted any acoustic model implementations for other languages. If you’d like to move the conversation over to the forums at https://www.politepix.com/forums we can take a look at what is involved in that.

    Hey Halle,
    The Library looks great. I’m the author of VocalKit which is a quick wrapper around pocket sphinx, but it was mostly a slight cleanup of a spike I did and never had much of a reason to work more on it. A lot of people are using it and I’m going to start pointing them in your direction. I don’t have much time to work on it and your project looks great.

    Hey Brian,

    Cool to hear from you, VocalKit is great. If you ever get a chance to try OpenEars out I’d love to get your feedback.
