Hello there. Today I want to tell you more about my last project, that i edited to final.I have made web application that support voice-to-text (voice recognition) in real time. It is working with all world languages with available lang code.. For instance: en-US, sk-SK, cs-CZ, de-DE and so on. I have demo for you, it is in English language for try this technology.You can use ESP8266 board (verified working on NodeMCU), I think it will work with ESP8266, Wemos D1 mini etc good. Or you can use Arduino with Ethernet shield W5100, it will work with Wiznet W5200 or W5500 too, you need only full compatible Ethernet2.h library. Web page is universal. If you write your own parser, you can use it with ESP32, RaspberryPi, OrangePi, C.H.I.P, Bigclown and more boards/microcontrolers.You can use in my demo this hardware:In my website you have full instructions how to use, read it carefully! You need to start your microphone manually for the first time in settings of webpage.English voice-to-text translation: https://arduino.php5.sk/PHP_en/ If you are interested for website code, you can contact me on: martinius96@gmail.comFor more informations visit my page and translate it to your language: https://arduino.php5.sk/ovladanie-hlasom.php
