Seems like a pretty useful app. From Thorin Klosowski … SoundGecko Converts Any Article Into an MP3 and Syncs with Dropbox, Drive, or an iPhone App:
At its core, SoundGecko is a new webapp that's essentially a text-to-speech transcription service. Drop a URL into SoundGecko and it converts the article into speech. On top of that it also integrates with cloud services and an iPhone app. By default the simplest way to use SoundGecko is to have it send you an email with the file, but you can integrate it into Dropbox or Google Drive for immediate syncing. You can also use the iPhone app to directly sync up articles you've converted, and use a Chrome extension to add articles on the fly.
As far as the voice is concerned, it's what you'd expect from a text-to-voice transcription. It's a little digital sounding and takes some getting used to. Still, for a free way to create your own MP3s of articles and have them synced up pretty much anywhere, SoundGecko works efficiently and simply. Currently SoundGecko is free for unlimited use. If you travel a lot and want to hear your favorite articles it's worth checking out.
