Amazon.com sells Greek pronunciation software, in the form of language learning software like Rosetta Stone and Pimsleur, as well as beginner's dictionaries with audio CDs included. Logos software teaches users how to pronounce specific words.
For those looking to learn Greek in its entirety, rather than simply needing help with pronunciation, Rosetta Stone Version 4 consistently earns high marks, while PC World believes Pimsleur Unlimited to be a solid choice and that Mango Passport is good for travelers.
For audio alone, Hippocrene Beginner's Greek has a four-star rating on Amazon.com. Logos is directed toward biblical scholars, but is one of the few specific pronunciation guides available.
