Android Studio Application Development integrated Baidu speech synthesis Use Method Example explains _android

First, speech synthesis refers to the conversion of text information into sound. The idea is to turn the text into a sound and let your application speak. Domestic in the industry more famous Third-party speech synthesis platform has Baidu voice and Hkust news fly.

The integration of this article is the Baidu speech synthesis, its main features are:

Totally permanent free

The industry pioneered a completely permanent free new form for developers to provide the most fluent and natural voice synthesis services. Completely free, permanently used, completely out of limits.

Offline Online Fusion mode

SDK can be based on the current network situation, automatically judge the use of local engine or cloud engine for speech synthesis, no need to worry about traffic consumption!

Multi-lingual multi-tone optional

Mandarin, Chinese and English mixed reading, male, female, you choose, more support speed, tone, volume, audio rate settings, so that your application has the most sweet and the most magnetic voice!

Smooth and natural synthesis effect

Speech synthesis technology industry-leading, synthetic effect close to real people voice, smooth and natural, and very expressive, give you the most comfortable hearing experience!

Baidu Voice of the official demo is written in the eclipse environment, and in the Android studio is a little different, below please see Baidu Speech synthesis using detailed steps (step by step do not jump impatient to eat hot tofu):

1, registered Baidu voice developer platform

Registered Baidu account, registered developer information, create applications, you can get APP ID, API key, and Secret key, in the development process will use these three values to authorize (very key), open speech synthesis service, if need to use off-line synthesis function also need to apply for offline authorization. Detailed steps please see Baidu Voice Access process.

2. Download Resources

Baidu Voice SDK Download, according to their own needs to download, this sample download is from the online fusion speech synthesis sdk_android version, address: Http://yuyin.baidu.com/tts/download

3, Integrated Baidu Voice Guide

3.1 Add jar packs and so libraries to engineering

The Libs directory in the development package is copied to the engineering directory as a whole (users of Eclipse), and the Libs directory includes the jar package and the so library of each platform, and the developer can cut the application needs. Galaxy_lite.jar is Baidu's Android public base library, if the project also integrates other Baidu SDK,
such as the Push SDK, an error message similar to the following appears in the packaging process:

[2013-10-22 11:02:57-dex Loader] Unable to execute Dex:multiple Dex files define
Lcom/baidu/android/common/logging/configuration;
[2013-10-22 11:02:57-voicerecognitiondemo] Conversion to Dalvik format failed:unable to
Execute dex:multiple Dex files define lcom/baidu/android/common/logging/configuration;

Please remove this Jar package. For users who use Android studio, you should put the jar packages in the Libs directory under the Libs directory, and then add library dependencies (don't forget). So library should be placed in the Jnilibs directory, jnilibs directory and Java, res in the same directory. Create your own if you don't have a corresponding directory. The entire structure is shown below:

3.2 Adding speech synthesis resource files

Place the DAT files in the data directory in the development package under the assets directory of the project, where the assets directory is in the same directory as Java and res in order to set the resource file parameters.

3.3 Permission Statement

Use Baidu Voice needs to declare the following permissions:

<uses-permission android:name= "Android.permission.INTERNET"/>
<uses-permission android:name= " Android.permission.ACCESS_NETWORK_STATE "/>
<uses-permission android:name=" android.permission.MODIFY_ Audio_settings "/>
<uses-permission android:name=" Android.permission.WRITE_EXTERNAL_STORAGE "/>"
<uses-permission android:name= "Android.permission.WRITE_SETTINGS"/>
<uses-permission android:name= " Android.permission.READ_PHONE_STATE "/>
<uses-permission android:name=" android.permission.ACCESS_WIFI_ State "/>
<uses-permission android:name=" Android.permission.CHANGE_WIFI_STATE "/>

4, Speech synthesis function code

4, 1 TTS initialization

Get TTS Instance SpeechSynthesizer = Speechsynthesizer.getinstance (); 
Set the app context (required parameters) Speechsynthesizer.setcontext (contexts);
Set up TTS listener Speechsynthesizer.setspeechsynthesizerlistener (Speechsynthesizerlistener); Text model file path, file absolute path (Offline engine usage) speechsynthesizer.setparam (speechsynthesizer.param_tts_text_model_file, Text_model_ 
File_full_path_name); Acoustic model file path, file absolute path (Offline engine usage) speechsynthesizer.setparam (speechsynthesizer.param_tts_speech_model_file, Speech_ 
Model_file_full_path_name); The local authorization file path, if not set, will use the default path. Set the temporary authorization file path,//licence_file_name replace the actual path to the temporary authorization file, only need to set when using temporary license file,///If offline authorization is opened in [Application management], it is recommended that the line code be deleted 
(Off-line engine) Speechsynthesizer.setparam (Speechsynthesizer.param_tts_licence_file, license_file_full_path_name); 
Replace the app ID (offline authorization) speechsynthesizer.setappid ("your_app_id") registered with the application on the Voice developer platform; 
Replace the Apikey and Secretkey (online authorization) Speechsynthesizer.setapikey ("Your_api_key", "Your_secret_key") for the Voice developer Platform registration application; Authorization Detection interface AuthInfo AuthInfo = SpeechsYnthesizer.auth (Ttsmode); Engine initialization Interface Speechsynthesizer.inittts (Ttsmode);

Note: Copy the resource files from the Assets folder to the SD card before initializing the settings for use. In addition, offline authorization temporary files valid for only 30 days, to the long-term use of voice off-line synthesis should be in the application management to open offline authorization.

4, 2 synthesis and playback

Mspeechsynthesizer.speak (text);

This interface is time-consuming, adopting queuing strategy, which will automatically join the synthesis queue and be synthesized and played in the Order of invocation.

OK, so your speech synthesis can be used, if you want to make more parameter settings, please see Baidu Speech synthesis official development document and Development manual.
