WP8语音识别UI导致未处理的异常

Question

SpeechRecognizerUI sr = new SpeechRecognizerUI();
sr.Settings.ListenText = "Say the recipient and body of the E-Mail";
sr.Settings.ExampleText = "Mom saying Happy Mother's Day";
//await Speak("Say the recipient and body of the E-Mail"); // TTS prompt
var recoResult = await sr.RecognizeWithUIAsync();
MessageBox.Show(recoResult.RecognitionResult.Text);

This throws an unhandled exeption and the WP8 app crashes. How do I fix this?

Answer 1

You may need to select a speech language goto phone SETTINGS then SPEECH .

In my settings the speech language is listed as none , once I selected a language ie English (United States) it seems to work.
