ZappTek today announced the release of iSpeak It 3.0, the latest version of the company’s software that allows users to take any document or Web feed and convert it into an MP3/AAC track in iTunes using a Mac’s built-in text-to-speech capabilities. This release adds Xgrid support so users can harness the power of multiple Macs to convert sections of a document into audio tracks. It also updates Web feed processing (including Atom feed support) and enhances document processing prior to conversion to audio (including greater control/functionality when splitting a document into multiple audio tracks). iSpeak It is priced at US$19.95 ($10 upgrade).
