How to realize text-to-Voice Toolbox with Java
This article mainly explains "how to convert Java into speech toolbox". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "Java how to achieve text-to-voice toolbox"!
Integration
Here we use Baidu Cloud's artificial intelligence speech synthesis API, individual users have a certain amount of free, basically enough, online speech synthesis supports rich SDK, basically popular languages can be easily accessed. Java, the world's most popular language, is used here.
Pom.xml introduces:
Com.baidu.aip
Java-sdk
4.12.0
Application.properties introduces:
# = =
# Baidu artificial Intelligence, apply for Baidu Cloud account and create an application
# = =
Bai-du.appId = *
Bai-du.apiKey = *
Bai-du.accessKeySecret = *
BaiDuProperties.java configuration entity:
@ Data
@ ConfigurationProperties (prefix = "bai-du")
Public class BaiDuProperties {
Private String appId
Private String apiKey
Private String accessKeySecret
}
Make a tool class:
/ * *
* Baidu Intelligent AI
, /
@ Component
@ Configuration
@ EnableConfigurationProperties ({BaiDuProperties.class})
Public class BaiDuUtils {
Private BaiDuProperties baiDu
Public BaiDuUtils (BaiDuProperties baiDu) {
This.baiDu = baiDu
}
Private AipSpeech instance
@ Value ("${file.path}")
Private String filePath
@ PostConstruct
Public void init () {
Try {
FileUtil.mkdir (filePath+SystemConstant.SF_FILE_SEPARATOR+ "voice")
Instance = new AipSpeech (baiDu.getAppId (), baiDu.getApiKey (), baiDu.getAccessKeySecret ())
/ / optional: set network connection parameters
Instance.setConnectionTimeoutInMillis (2000)
Instance.setSocketTimeoutInMillis (60000)
} catch (Exception e) {
E.printStackTrace ()
}
}

Public String text2Voice (String text,Boolean per) {
SslUtils.ignoreSsl ()
HashMap options = new HashMap ()
If (per) {
Options.put ("per", "3")
} else {
Options.put ("per", "4")
}
TtsResponse res = instance.synthesis (text, "zh", 1, options)
Byte [] data = res.getData ()
If (data! = null) {
Try {
String file = "voice" + SystemConstant.SF_FILE_SEPARATOR+UUID.randomUUID () + ".mp3"
Util.writeBytesToFileSystem (data, filePath + SystemConstant.SF_FILE_SEPARATOR + file)
Return file
} catch (IOException e) {
E.printStackTrace ()
}
}
Return null
}
}
Be careful
Please note that the text length must be less than 1024 bytes
There may be problems with https authentication in local testing. Just call the ignoreSsl method.
