One tool that has recently popped onto the list is ipadio. Gordon Wells, a language teacher and developer, who nominated it for the list, told me more about it. and how he uses it. He wrote, it is ..
"as an excellent user-friendly and free tool for genering audio material. I use it in conjunction with WordPress (which I would also nomiate) to create media-rich materials incorporating text, audio, and images – sometimes also incorporating YouTube (also nominated!) for video material as an alternative, or in addition to, the audio.
Ipadio is extremely flexible. You can phone in by landline or mobile (the latter meaning you can create materials "on the hoof"), and your basic webpage is created instantaneously. If you're concerned about sound quality over a telephone line there is also an MP3 upload option.
There are numerous examples here, on my project blog, of Ipadio files embedded into WordPress posts, using a mobile or landline: guthan.wordpress.com/
Here's an MP3 sample, used for uploading some music, onto my personal blog: gordonwellsuist.wordpress.com/2010/05/08/doubling-up-on-shak-and-sax-musical-bilingualism/
Thanks for the information, Gordon, hope others enjoying take a look.
