Please respect others' labor achievements and repost the Source: [Android speech synthesis TTS] Baidu Speech Access Method and usage tips
Ps.

Relying on Baidu open cloud, Baidu speech provides industry-leading, permanently free voice technology services to partners. Currently, the services available include speech recognition, semantic parsing, and speech synthesis, in the future, we will continue to provide open resources, multi-round dialogs, and other technical services. Through sdks, REST APIs, and offline Development kits, we will meet the development needs of different developers.

Currently, Baidu speech provides free voice access, and the speech synthesis quality is acceptable, but offline TTS is not yet available.

Service Access Process

Integrated Development

Import jar packages and so files related to Baidu speech

Tip:

Copy the libs directory in the Development Kit to the project directory. The libs Directory includes the SO library of each platform. developers can delete the directory as needed. Galaxy_lite.jar is a public basic library of Baidu Android. If other Baidu sdks, such as PushSDK, are integrated in the project, the following error message is displayed during the packaging process:

[11:02:57-Dex Loader] Unableto execute dex: Multiple dex files defineLcom/baidu/android/common/logging/Configuration; [11:02:57-VoiceRecognitionDemo] Conversion to Dalvik format failed: unable to executedex: Multiple dex files define Lcom/baidu/android/common/logging/Configuration;

Remove the Jar package. If the Eclipse ADT version plug-in is earlier than 17, you need to manually add the dependent library by adding Project => Properties => Java Build Path => Libraries => AddJAR... 3

For ease of use, I have further encapsulated the Baidu speech synthesis engine and encapsulated it into SpeechUtil for convenient calling:

Usage:

package com.jph.tts;import android.app.Activity;import android.os.Bundle;import android.text.method.ScrollingMovementMethod;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;import com.baidu.tts.sample.R;public class HomeActivity extends Activity implements OnClickListener {protected static final int UI_LOG_TO_VIEW = 0;private TextView logView;private EditText inputTextView;private Button startButton;private SpeechUtil speechUtil;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_home);logView = (TextView) findViewById(R.id.logView);logView.setMovementMethod(new ScrollingMovementMethod());inputTextView = (EditText) findViewById(R.id.inputTextView);speechUtil = new SpeechUtil(this);}@Override    public void onClick(View v) {        switch (v.getId()) {        case R.id.btnStart:        speechUtil.speak(inputTextView.getText().toString());            break;        case R.id.btnPause:        speechUtil.pause();        break;        case R.id.btnResume:        speechUtil.resume();        break;        case R.id.btnStop:        speechUtil.cancle();        break;        default:            break;        }    }}

Because Baidu TTS requires Internet resolution, you need to grant the corresponding permissions to the application:

<uses-permission android:name="android.permission.INTERNET"></uses-permission>    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
