Most
voice posts display with a Flash player that allows you to play the voice post directly in the entry. However, you can also click the "VoicePost" link to download the file and play it with your computer's software. Additionally, the "transcribe" link allows authorized users to post a written transcription. You can see an example of a voice post
here.
Listening to Voice Posts
Voice posts are encoded as either MP3, WAV, or Ogg Vorbis files, depending on the
journal's settings. MP3 voice posts will display using an in-line Flash player, while others need to be downloaded to your computer in order to be played.
Ogg Vorbis files are compressed audio, similar to the default MP3 setting, while WAV files are uncompressed audio files that are typically much larger in size.
Transcribing Voice Posts
Authorized users (which always includes yourself, and can include either all of your friends or one of your custom friends groups) can transcribe your voice post by clicking the "transcribe" link.
Authorized users can only transcribe a voice post once. Once you transcribe your own voice post, no other transcriptions can be added. Additionally, there is a limit of 10 transcriptions for each voice post: nine for other users and the last for you. After the tenth transcription, new ones will replace the one previously saved as the tenth.
The most recent transcription will appear in the voice post journal entry. Transcriptions do not allow HTML, and are limited to 4096 characters. You can see a history of transcriptions by clicking the "Transcribed" link at the bottom of a voicepost.
Auto-transcription
LiveJournal used to offer an auto-transcription option for short voice posts. This option is no longer available, despite the fact that a checkbox still exists for the option in the voice post settings.
