14 APIs for Natural Language Processing and Speech Recognition

COTOHA API is capable of high-accuracy analysis of Japanese language, which has been considered as one of the most difficult languages.
It can be used for text analysis and an communication engine (Text/Voice).

Parsing

Since this API can extract "Who(what)?" and "What wrong?" from the input sentence by word unit called morpheme, it can be applied to data mining.

Reference Resolution

This API can extract pronouns such as "He/She", extract an antecedent that correspond to those pronouns, and outputs them as a pair of pronoun and object. In the case of analysis of conversation logs, it can make it more precise by replacing pronouns with antecedents.

Speech Recognition

You can receive voice data in file or streaming formats and return the formatted text data. You can also register a customer induvidual dictionary dedicated to speech recognition.
