When you decide to transfer a document to iTunes you have the opportunity to define the song name, artist, album and genre for the track that's created. iSpeak It remembers your prior artist, album and genre entries so you can define them once and use them for all of your documents.
The album is taken from the file name or web feed that was loaded. Weather and Directions are automatically put in albums titled Weather and Directions respectively. Under most circumstances this is all you need so it's likely you can let iSpeak It take care of the album name.
The playlist can be used to define where to put the track. Leave the playlist blank if you don't want the track in a playlist.
You can use the Encoder setting to determine what format iTunes will use to convert your document. This setting is independent of your iTunes import preferences; your iTunes preference remain unchanged. You can keep your iTunes encoder set to import CDs while ensuring that iSpeak It uses the most appropriate encoder for speech.
Tracks can be made bookmarkable in that they remember their last location in the track when you stop listening to it. This options allows you to listen to a document, stop to listen to something else and then come back to it and continue where you left off. You also have the option of making AAC encoded documents Audiobooks so that they appear with (and can be manipulated as) Audiobooks purchased from the iTunes store.
You can also delete an existing track with the same name since iTunes won't automatically overwrite an existing track. If you choose not to delete existing tracks then you can end up with numerous weather tracks (for example) instead of simply refreshing the track every time you do a download. The actual file will be moved to the Trash (it's what iTunes does when you delete a song from your library).
The split option allows you to to take a long document and partition it into multiple tracks, much like an audio book. You can control whether or not you want to split on words (separated by whitespace), sentences (separated by ., ?, or !), paragraphs or page breaks. Paragraph splitting will first check to see if there are blank lines, and if there are, use them to identify paragraphs. If there are no blank lines iSpeak It will use carriage returns (the default in Word documents) to identify paragraphs. Alternatively, you can specify a sequence of characters to use for splitting your document (with the sequence being removed prior to transfer). This is useful when you want to split a document into chapters — add a unique set of characters (say "=======") to the beginning of each chapter and iSpeak It will generate separate tracks for each chapter. Page breaks work well with Word documents and PDFs — iSpeak It will automatically put a page break at the end of every page when processing a PDF document.
Note that the split option is ignored for Directions and Weather — for these splitting doesn't make sense (for example, splitting based on paragraphs will lead to lots of small tracks where you really want all of the information in one track). This way you can keep your split settings optimized for your documents. Further, when splitting is active your RSS feeds will automatically split between articles — each article will be a separate track in an album for that feed.
The Xgrid option allows you to use multiple Macs on a network to process the individual sections of a document (as defined by your split settings).
Selecting apply replacement rules will have all defined rules applied to a document before it is transferred to iTunes.
