There is a myth that learning a new language is difficult. But that is not really true - with a little time and the proper tools, it is quite easy. The main problem with learning a new language is that people expect amazing results really quickly. This is a normal human desire, but it often distracts us from achieving good, retainable outcomes. The Planet Speaks - is a tool designed to provide solid learning results. We have specifically built our system to be as effective as possible by incorporating different learning methods. We start with a scientifically proven spaced repetition system. We push that system to the limits by using machine learning algorithms. The Planet Speaks app continuously monitors your answers, in order to generate the best lessons for you, and choose the words you need to learn. You will repeat words at the right time, and as frequently as you need, to really get a solid grasp of the lesson. It is widely known that you learn better when you have more connections to the content in different parts of your brain. You learn through visual images, audio presentation, how completely you are able to incorporate the content, and how often you are presented with material. Pronunciation of words, how they are used in phrases, even body movement - those factors all add to your learning efficiency. At The Planet Speaks, we utilize many different methods that your mind uses to learn - pictures, pronunciation or drawing, videos with native speakers, and so much more. We made the app that we would want to use to learn a new language. You will find: - 9 languages to learn - English, Chinese, Italian, Portuguese, Spanish, French, Japanese, Russian, German. We are about to add more languages in future updates. - 5800+ most essential and frequently used words and phrases. We cover all topics that might occur in daily usage. - We provide audio and video for all words and phrases that are used in the lesson, spoken by real native speakers. You will have more than 70 hours of video for your learning experience. - This diverse learning system covers almost all of your senses, plus we have 10 additional exercises to reinforce your learning experience. - A spaced repetition system improved by machine learning, that will generate the right lessons for you. - Privacy - we don't collect and sell any of your data. It's just that simple. The Planet Speaks is a subscription-based app. You will be able to try it before you subscribe, with no commitments. We are a small team, and we are working hard to make a fair product that works well for you, and meets our teaching goals. We are open to any comments and suggestions. If you find a bug or something needs a correction, if you want to add some additional functionality in the app, if you want your language to be added, or if you just want to say Hi, please contact us.
