如何限制'watson-HTML5-speech-recognition'仅识别数字 [英] How do I constrain 'watson-HTML5-speech-recognition' to recognize only numbers

问题描述

Hi! I'm devloping a speech recognition app using 'watson-html5-speech-recognition'. How can I constrain the recognition context to recognize only numbers (i.e the recognized word should be a number e.g 101, 40, 76, 4.. etc) and not (one hundred and one, forty, seventy six, four.. etc).

I'm working on a math app, where the result should never be a string text, just numbers. Thanks

我尝试过：



我尝试使用javascript在识别后解析识别的文本（如果是isNumber（）），但我认为最好在识别之前将说出的单词限制为仅数字而不是之后..

What I have tried:

I tried using javascript to parse the recognized text(if isNumber()) after recognition, but I think it will be better to constrain the spoken words to only numbers before recognizing and not after..

推荐答案

语音识别将语音转换为字符串，我认为不可能也不适合与语音识别引擎纠缠在一起。此外，在首先解析之前（从音频信号到实际字符串），你无法识别任何东西。

Speech recognition converts spoken words to string, and I do not think it is possible, nor suitable, to entangle with the speech recognition engine for that. Moreover, you cannot recognize anything before having it parsed in the first place (from audio signal to actual string).

你可能不得不重新考虑这个观点：）
