Which topics on Quora are related to the technology behind Apple Siri?
According to ProgrammableWeb, Apple Siri uses more than 35 APIs [1]. For instance, Siri accounts for about a quarter of the queries fielded by Wolfram|Alpha [2]. Yelp is another of the APIs Siri uses [3].
Originally, Siri was built on SRI International CALO (Cognitive Assistant that Learns and Organizes) [4]. What is not so widely known is that SPARK (SRI Procedural Agent Realization Kit) [5] forms the heart of CALO’s task execution.
It’s fairly certain that Nuance Communications ASR (Automatic Speech Recognition) is behind Siri [6]. And in terms of Cloud Computing, apparently Apple’s new solar-powered data center in North Carolina “is handling at least part of the workload for Apple’s Siri voice command system” [7].
