Then it will create a new typescript file and HTML file.This post was co-authored by Yinhe Wei, Runnan Li, Sheng Zhao, Qinying Liao, Yan Xia, and Nalin MujumdarĪn important element of language learning is being able to accurately pronounce words. You can create a new component through using the below command: ng g c speech-to-text Now we have reviewed the service file, next we have to call this service in a component. Then we call “event listener” for getting identified words and assign those words to the “tempWords” variable to access later. Yue Chinese (Traditional Hong Kong) zh-yue. ![]() I will list the supported languages below that you can set: We enable return interim results and set language as our need. recognition = new webkitSpeechRecognition(). Next, we create and a new instance of webkitSpeechRecognition and initialize it by passing values to properties of webkitSpeechRecognition. declare var webkitSpeechRecognition: any Otherwise Angular will not recognize it because “webkitSpeechRecognition” is not a library. First, we declare “webkitSpeechRecognition ” as per the below line. Now we call webkitSpeechRecognition API in here.
