Savannah’s Urban Planet Mobile launched a line of audio English lessons for mobile phones Sept. 10.

Company CEO Ben OliverSmith said the Urban English products are to tap into the more than 1.1 billion people learning the language and 3.3 billion cell phone users worldwide.

“Having successfully built an audio publishing company, I researched the biggest audio market worldwide.  Next to music, language-learning products are it,” he said.

Mr. OliverSmith previously founded Sounds Publishing Inc., which distributed audio books through Apple Inc.’s iTunes music player and online store.

The lessons are immediately available for speakers of 10 languages—Arabic, Bengali, Hindi, Japanese, Korean, Mandarin, Portuguese, Russian, Spanish and Thai—with more planned for 2009.

The lessons include word-a-day, phrase-a-day, learning comprehension and conversational audio files that can be delivered to mobile devices digitally.
