If you are writing a telephony system using the Twilio API, Tropo API, or Cloudvox API, you can interface with YouCantCall.us to shield your system from phone spam. Now wouldn’t it be great if the YouCantCall.us API could be integrated into a “block” button that appeared on standard phones?
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.
