The API.AI .NET SDK by API.AI aims to simplify API integration features of natural language processing into new applications. Resources include a programming interface to make text and voice requests to the API.AI. Additional resources could be useful to add usages to a module, add field to a class, and initialize object with Keys. See how JSON.NET helped with parsing implementation at http://www.newtonsoft.com/json
Google has added semantic time support to the time fencing feature of its Awareness API. Prior to semantic time support, time fencing was limited to absolute/canonical time (e.g. 10:00 AM). Semantic time enables the use of more natural time refererences (e.g. after sunset, the weekend, etc.)
Google has announced a large overhaul of its Cloud Speech-to-Text product (formerly the Google Cloud Speech API). Google Cloud Speech-to-Text now supports a selection of pre-built models, automatic punctuation, recognition metadata, and standard service level agreement (SLA).
