Question

我是Android平台的新手。现在我正在处理TTS(Text to Speech)。如果我在TextArea中输入文本，并且我希望在单击“说出”按钮时将其转换为语音。

任何人都可以帮助我吗？

Answer 1

文字转语音内置于Android 1.6+中。这是一个如何做的简单示例。

TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

Here are instructions有关如何从Android SDK Manager下载示例代码的信息：

启动Android SDK Manager。

一个。在Windows上，双击Android SDK目录根目录下的SDK Manager.exe文件。

湾在Mac或Linux上，打开Android SDK中tools /目录的终端，然后执行android sdk。
展开最新Android平台的软件包列表。
选择并下载SDK样本。下载完成后，您可以在此位置找到所有样本的源代码：

试试这个，很简单： ** speakout.xml：**

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#3498db"
android:weightSum="1"
android:orientation="vertical" >
<TextView
android:id="@+id/txtheader"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_weight=".1"
android:gravity="center"
android:padding="3dp"
android:text="Speak Out!!!"
android:textColor="#fff"
android:textSize="25sp"
android:textStyle="bold" />
<EditText
android:id="@+id/edtTexttoSpeak"
android:layout_width="match_parent"
android:layout_weight=".5"
android:background="#fff"
android:textColor="#2c3e50"
android:text="Hi there!!!"
android:padding="5dp"
android:gravity="top|left"
android:layout_height="0dp"/>
<Button
android:id="@+id/btnspeakout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=".1"
android:background="#e74c3c"
android:textColor="#fff"
android:text="SPEAK OUT"/>
</LinearLayout>

和你的 SpeakOut.java：

import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class SpeakOut extends Activity implements OnInitListener {
private TextToSpeech repeatTTS;
Button btnspeakout;
EditText edtTexttoSpeak;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.speakout);
    btnspeakout = (Button) findViewById(R.id.btnspeakout);
    edtTexttoSpeak = (EditText) findViewById(R.id.edtTexttoSpeak);
    repeatTTS = new TextToSpeech(this, this);
    btnspeakout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            repeatTTS.speak(edtTexttoSpeak.getText().toString(),
            TextToSpeech.QUEUE_FLUSH, null);
        }
    });
}

@Override

Answer 5

快速测试TTS系统的简约示例：

private TextToSpeech textToSpeechSystem;

@Override
protected void onStart() {
  super.onStart();
  textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                String textToSay = "Hello world, this is a test message!";
                textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
            }
        }
   });
}

如果您不使用本地化消息textToSpeechSystem.setLanguage(..)也很重要，因为您的用户可能并非都将英语设置为默认语言，因此单词的发音将是错误的。但是对于测试TTS一般来说这个片段就够了
