当我尝试将语言设置为 SpeechRecognize (WP 8.1) 时不起作用

Question

当我尝试将语言设置为 SpeechRecognize (Windows Phone 8.1) 时，它会运行异常。但是在文档中告诉我按照我正在做的方式做 D；

这行得通：

private async void Button_Click_1(object sender, RoutedEventArgs e)
        {
            var rec = new SpeechRecognizer();
            await rec.CompileConstraintsAsync();
            rec.UIOptions.AudiblePrompt = "Aguardando o comando";
            var stream = await rec.RecognizeWithUIAsync();

        }

这不起作用：

private async void Button_Click_1(object sender, RoutedEventArgs e)
        {
             var rec = new SpeechRecognizer(new Windows.Globalization.Language("pt-BR"));
            await rec.CompileConstraintsAsync();
            rec.UIOptions.AudiblePrompt = "Aguardando o comando";
            var stream = await rec.RecognizeWithUIAsync();

        }

有人可以帮助我吗？

我认为这是因为您安装的 Locale 不是那种语言。如果你想确定，试试这个：

private async void Button_Click_1(object sender, RoutedEventArgs e)
    {
           try(){
         var rec = new SpeechRecognizer(new Windows.Globalization.Language("pt-BR"));
        await rec.CompileConstraintsAsync();
        rec.UIOptions.AudiblePrompt = "Aguardando o comando";
        var stream = await rec.RecognizeWithUIAsync();
            }
         catch(Exception e)
           {
             Debug.WriteLine(e);
            }

    }
