Is there a library or web service that provides pronunciations for text?

Question

Is there a library or web service that can tell you the pronunciation of a string? I'm thinking of character-based languages, where the pronunciation of the word is not apparent from how it's written.

Answer 1

Check out the Wordnik API:

http://developer.wordnik.com/

Free API key will get pronunciations, definitions, and a whole lot more. Easy to use, and the API documentation site is interactive and lets you get your feet wet quickly. Lots of wrappers in various languages.

Disclosure: I work there and love it.

This is a similar question. Research the CMU Pronouncing Dictionary.
