仅Web语音API数字

Question

I am writing a web application which requires me to recognize spoken digits. I am using the javascript Web Speech API. It is working quite well at the moment, but I'd love to restrict the recognition to digits only, to improve the accuracy. One thought I've had is to set the grammar, but I cannot for the life of me work out how. Is anybody aware of a way to make this restriction?

Answer 1

Speech Grammar could be a way to do this but it is not yet supported by any browser. http://www.w3.org/TR/speech-grammar/ .For the time being you have to use a javaScript function like isDigits()
