为什么我在 js 上的语音识别不起作用?

问题描述

我一直在关注 this 并补充了各种 YouTube 视频和堆栈溢出问题.但是，我不确定为什么我的语音识别不起作用.我被问到很少允许使用麦克风.

我希望用户麦克风拾取用户的语音并将其附加到某个输入值.这是我的代码:

const 识别 = new SpeechRecognition();识别.interimResults = true;var 识别 = new SpeechRecognition();识别.onresult = 函数(事件){if (event.results.length > 0) {name.value = event.results[0][0].transcript;}}识别.addEventListener(结束"，()=> {识别开始()；});var 识别 = new SpeechRecognition();识别.onresult = 函数(事件){if (event.results.length > 0) {location.value = event.results[0][0].transcript;}}识别.addEventListener(结束"，()=> {识别开始()；});var 识别 = new SpeechRecognition();识别.onresult = 函数(事件){if (event.results.length > 0) {state.value = event.results[0][0].transcript;文档.care.submit();}}识别.addEventListener(结束"，()=> {window.location.pathname = '/care';文档.care.submit();});

以下是我遇到的错误:

未捕获的引用错误:未定义识别在 HTMLButtonElement.onclick

未捕获的语法错误:已声明标识符识别"

无法加载资源:net::ERR_FAILED

解决方案

我使用 SpeechRecogition 已经有一段时间了，一开始可能会非常棘手.但是，我发现这个要点对我非常很有帮助.希望这段代码可以帮助您像对我一样理解 SpeechRecogition.

I've been following this and supplementing it with various youtube videos and stack overflow questions. But, I am not exactly sure why my speech recognition is not working. I am asked about allowing microphone access rarely.

I want the user microphone to pick up the user's speech speech and append it to a certain input value. Here's my code:

const recognition = new SpeechRecognition();
              recognition.interimResults = true;

              var recognition = new SpeechRecognition();
                recognition.onresult = function(event) {
                  if (event.results.length > 0) {
                    name.value = event.results[0][0].transcript;
                  }
                }

              recognition.addEventListener("end", () => {
                recognition.start();
              });

              var recognition = new SpeechRecognition();
                recognition.onresult = function(event) {
                  if (event.results.length > 0) {
                    location.value = event.results[0][0].transcript;
                  }
                }
              
              recognition.addEventListener("end", () => {
                recognition.start();
              });

              var recognition = new SpeechRecognition();
                  recognition.onresult = function(event) {
                    if (event.results.length > 0) {
                      state.value = event.results[0][0].transcript;
                      document.care.submit();
                    }
                  }
              
              recognition.addEventListener("end", () => {
                window.location.pathname = '/care';
                document.care.submit();
              });

Here are the errors I am getting:

Uncaught ReferenceError: recognition is not definedat HTMLButtonElement.onclick

Uncaught SyntaxError: Identifier 'recognition' has already been declared

Failed to load resource: net::ERR_FAILED

解决方案

I've worked with SpeechRecogition for a bit, and it can be very at first tricky. However, I found that this gist is very helpful for me. Hopefully this code can help you understand SpeechRecogition more like it did with me.
