ESL Robot is an award-winning artificial intelligence application. It performed strongly at the annual Loebner Artificial Intelligence Contest. In 2016, it won the 2nd place in the final round of the contest

This application is designed to help English learners practice speaking English. Learning a language requires a lot of practice, but it is often difficult or expensive to find someone to practice English with. ESL Robot is specifically designed to help users practice speaking. Requiring only an internet connection, it is a highly convenient and cost effective way to simulate conversations with a native speaker of English. ESL Robot never tires in providing human-like responses to all your inquiries on a range of subjects. In addition to speaking its response, ESL Robot displays the written text of the dialogue onscreen. In the event the bot fails to recognize your voice, you can type in your questions and responses. This serves as an excellent format to study, practice and improve your English.

After years of development, ESL Robot has become an experienced "English tutor". Its responses are both educational and entertaining. It can tell you jokes, riddles, and proverbs. You can ask grammar questions. It knows almost all the grammatical terms used in an English grammar handbook. It knows irregular verbs, and irregular plural forms of certain nouns; You can ask for advice on how to learn English. A predominant feature of ESL Robot is its capability to check for spelling and grammatical errors. When you type in a question, ESL Robot checks for common ESL spelling and grammar errors. Currently over 2,500 common ESL errors have been collected and stored in the program. When an error is found, ESL Robot will give the user a response such as, “You made an error. "ENJOY" must be followed by a gerund not an infinitive.”

ESL Robot is knowledgeable. It knows what happened today in history; it can tell you the capital city, population, and location of each country; it can tell you who is the current president of which country, and who wrote which book. It can also answer many general knowledge questions on geography, science, sports, pop culture, and current events, such as “What is the largest city in Spain?” or “How far away is the sun?” or “Who won the most gold medals in Beijing 2008?” ESL Robot has a good memory. If you tell it your name, age, birthday, etc., it will remember them when you ask it later in the conversation.


The app consists of two parts. When you open the app, you'll see two buttons "For Beginners" and "For Advanced". If you choose "For Beginners", you can type in your questions and responses; the robot will speak back to you with a voice. If you activate the microphone, you can speak instead of typing. When you speak, the text will appear in the box for you to look at. If the app fails to recognize your voice input, you can correct the mistakes by typing before you click on the SEND button. If you choose "For Advanced" button at the beginning, you'll be able to speak to ESL Robot without clicking on the SEND button. Now you can talk to ESL Robot just like talking to your human English tutor.

Disclaimer: All the answers given by the bot are for language practice purposes; they are usually correct, but may not be 100 percent accurate.
