Replace Jott with Free Dial2Do Message Service
As with Jott, you simply call the special Dial2Do number, say what you want to do ("text," "e-mail," "reminder," "Twitter," etc.), name the recipient ("me," "Bob," etc.), and then record your message. The service does employ both computer-driven transcription and human operators who check it for accuracy, but offers to turn off transcription "if you are working for the CIA or planning a major bank heist." Heh, heh.
You can import up to 100 contacts from the likes of Gmail and Outlook, and use Dial2Do with services like Jajah, Jaiku, and Twitter. I took Dial2Do for a quick test-drive, and it delivered an accurately transcribed reminder (and a link to the actual audio recording) to my inbox within about five minutes. Spoiled as I am by all things free, I've given the service my Jott speed-dial slot -- at least until it leaves beta and ceases to be free.
