VoiceBase acts as your personal and public voice recording database. No matter what your recordings—phone conversations, interviews, or presentations—you can import them into VoiceBase and it will transcribe them for you. Once it's done, you can edit the transcription manually for any errors.
You can then search the database (either limited to your own recordings, or including public content) for words within the transcriptions. It will highlight your search terms so you can go straight to the part of the recording or transcription that you need—perfect for condensing and extracting quotes from an interview, or for finding important points in a lecture. Right now, you get two hours of storage for free, but you can upgrade to more for a small fee. -Lifehacker
I am not sure I would recommend actually using this as e-learning, but if you want to create some SCORM content this tool may be for you. This marketing from a Microsoft blog: "Have you heard of the free Microsoft Learning Content Development System? We've just updated it to version 2.5, which now supports more complex content, and is Firefox and Silverlight 4 compatible. It is a free tool that lets you create high-quality, interactive, online courses, and publish them in SCORM 1.2 packages (exactly what your Learning Platforms like to consume!)." -Stephen Downes
