Google keeps on adding skills to the assistant which includes association with HDFC bank's 'Eva' chat-bot for handling banking related queries.
2. Siri by Apple
Siri is the intelligent assistant present in Apple ecosystem. It uses natural language interface to take user commands. Siri adopts the user's language, type of search patterns, preferences with continuous use. It was originally developed by SRI international Artificial Intelligence Center and uses advanced machine learning algorithms to function. The speech recognition engine is developed by nuance Communications.
Siri supports a wide range of user commands, including performing phone actions, checking basic information, perform basic math, searching the Internet, navigating areas, finding information on entertainment, and is able to engage with iOS apps.
3. Alexa by Amazon

6. Watson by IBM
Last but not the least, Watson, developed by big blue IBM and named after it's first CEO Thomas J. Watson. It is unlike simple virtual assistants as Alexa or Siri, but a question answering computer system capable of answering questions asked in natural language. IBM has released Watson APIs for other software application providers which includes natural language processing, sentiment analysis, speech tone recognition etc. These APIs can be used for development of chat-bots. Also Watson is useful in making decisions for various medical treatments. Watson uses IBM's DeepQA software and the Apache UIMA (Unstructured Information Management Architecture) framework. IBM also have provided many ways to train Watson through Watson Knowledge Studio. It is a next step towards AI that answers almost anything.
These are some famous smart assistant, that improve our experience while using devices and services. Some honarable mentions are 'M' by Facebook (discontinued from January 2018) and open source 'Mycroft' by Mycroft AI.

ReplyDeleteArticle is very informative. Akshay what do you think? how virtual assistant will affect search results?
ReplyDeleteAs the virtual assistant will be picking up keywords from user input to search on search engine, the search results will depend on how the assistant interprets user input and results provided by search engines. That is why we may have different user experience while using different assistants.
