Requirements

Network : above TLS v1.2

OS : above Android 5.0 (API level 21)

Language : Java , Kotlin

How to integrate into your application?

Basically, the SDK provide a flexiable way for integration.\ Only mandatory components for integration are 'Nugu Interface' and 'Nugu Core'.\ The others are utility compoenents to easy integration.\ But, we explain an simple method here.

Method 1 : (The most easy way) Use "Nugu Android Helper"

Setup dependency

At module's build.gradle

dependencies {
    implementation 'com.skt.nugu.sdk:nugu-android-helper:$latestVersion'
}

Create Nugu Android Client

The client provides most of the APIs for status notification and control of the SDK.

val client = NuguAndroidClient.Builder(
        context,
        authDelegate,
        defaultAudioProvider
        ).endPointDetector(EndPointDetector(EPD_MODEL_FILE_PATH)).build()

Use SpeechRecognizerAggregator

If the application use "Keyword Detector" to wake up, recommend to use.\ Otherwise, skip this part.\ This class provides a convenient way to manage "Keyword Detector" and "SpeechProcessor" easily.\ The constructor requires three parameters. Look at documentation about details.

val speechRecognizerAggregator = SpeechRecognizerAggregator(
                                    KeensenseKeywordDetector(keywordResource), 
                                    SpeechProcessorDelegate(client?.asrAgent), 
                                    audioSourceManager)
