I saw a post about sending audio email as an alternate way of delivering messages in your own voice and allowing for communication of the proper tone–something not easily captured by text. The link led me to an advertisement for an audio transcription service. Why use a service when you can do the same for free if you have a PDA equipped with a voice recorder. Simply record a voice note and synchronize your device with your computer. Locate the voice note file on your device and copy it as a .wav or .mp3 file within an email message. Don’t get too wordy as the file can get pretty big fairly quickly depending on your recorder settings and the length of the voice note.
