Earlier this year, ProgrammableWeb reported that Expert System, a leading semantic software company, had released the Cogito Intelligence API which allows semantic processing and analysis functionality to be integrated with government, intelligence, law enforcement and other types of security software systems and applications. Expert System has just announced the launch of a "freemium" version of the Cogito Intelligence API which is available on Mashape, the cloud API Marketplace.
AISpeech is the API behind a Chinese language and pronunciation learning website, AIChinese. You may know that Chinese is a tonal language. Where tones and inflection are used in English to convey emotion or differentiate between a declarative statement and a question, in tonal languages like Chinese, different tones on the same syllable can be altogether different words. The AISpeech API gives you access to a language processing engine which is capable of detecting spoken words and evaluating if the appropriate tone is used.
