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 ()

}

}

/ * *

* speech synthesis

* there may be problems with https authentication in local testing. Just call the ignoreSsl method.

* @ param text composite text, using UTF-8 encoding, please note that the length of the text must be less than 1024 bytes

, /

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.
