我可以保持语音识别听下去？ [英] Can I keep the speech recognizer listening indefinitely?

问题描述

当我称之为 SpeechRecognizer 对象的 startListening 法，语音识别开始监听讲话。我想创建一个等待一个特定关键字的语音服务：当用户说，这个关键字的语音识别器检测到这个关键字，那么该服务准备好接收用户的语音命令

When I call the startListening method of a SpeechRecognizer object, the speech recognizer starts listening for speech. I would like to create a service that is waiting for speech of a specific keyword: when the user says this keyword and the speech recognizer detects this keyword, then the service becomes ready to receive user voice commands.

为此，新的 SpeechRecognizer 实例化，我应该叫其 startListening 方法后：我可以保持语音识别听下去？

To this end, after a new SpeechRecognizer instantiated, I should call its startListening method: can I keep the speech recognizer listening indefinitely?

推荐答案

在 Android的语音识别可以通过意向额外的数据定制。请参阅<一href="http://developer.android.com/reference/android/speech/RecognizerIntent.html#EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS">the Android的文档。

The Android Speech recognizer can be customized through the intent extra data. See the android documentation.
