android在使用dragonSDK初始化连接时出错

Question

我无法弄清楚这段代码出了什么问题。我正在将 Nuance 的 DragonSDK 用于基于 ASR 的 android 应用程序。我认为加载 lib 文件和初始化与服务器的连接存在一些问题。我检查了 libs 目录中存在的依赖项 (.jar) 文件。还检查了 lib 文件的 gradle 条目。

提前谢谢你。

Answer 1

看起来触发其他的错误是“ANDROID_CONTEXT参数没有传入！！！”检查您的 SpeechKit.initialize 应该类似于
SpeechKit.initialize(context, speechKitAppId, speechKitServer, speechKitPort, speechKitSsl, speechKitCertSummary, speechKitCertData, speechKitApplicationKey);

http://dragonmobile.nuancemobiledeveloper.com/public/Help/DragonMobileSDKReference_Android/SpeechKit_Guide/ServerConnection.html

还要检查您是否拥有正确的权限：

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

最后，检查库 libnmsp_sk_speex.so 是否已添加到您的项目中

Answer 2

我遇到了同样的问题，我可以确认您需要确保添加 .so 的所有库文件夹（不仅仅是 .jar）。

我还将初始化更改为：

SpeechKit.initialize（上下文，speechKitAppId， 语音套件服务器， 语音套件端口， SpeechKitSsl, 无效的， 无效的， SpeechKitApplicationKey);

祝你好运。
