Speechly Android Client

This repository contains the source code for the Android client for Speechly SLU API. Speechly allows you to easily build applications with voice-enabled UIs.

Requirements

• Android 8.0 (API level 26) and above
• Android Emulator version must be >= 30.4.5

Usage

Configuration

Add android-client to your build.gradle dependencies.

dependencies {
  implementation 'com.speechly:android-client:0.1.11'
}

Remember to add permissions for microphone input and network connections as well as audio stream sampling in AndroidManifest.xml:

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>

Client usage

Create a client, usable for the total lifetime of the app:

val speechlyClient: Client = Client.fromActivity(activity = this, UUID.fromString("your APP_ID"))

Then, create a button which handles the opening and closing of the microphone:

var button: SpeechlyButton = findViewById(R.id.speechly)

var buttonTouchListener = object : View.OnTouchListener {
        override fun onTouch(v: View?, event: MotionEvent?): Boolean {
            when (event?.action) {
                MotionEvent.ACTION_DOWN -> {
                    speechlyClient.startContext()
                }
                MotionEvent.ACTION_UP -> {
                    speechlyClient.stopContext()
                }
            }
            return true
        }
    }

button.setOnTouchListener(buttonTouchListener)

The final thing is to react to the events the API sends back:

speechlyClient.onSegmentChange { segment: Segment ->
    val transcript: String = segment.words.values.map{it.value}.joinToString(" ")
    print(transcript)
}

Check out the Speechle Android Client Example for a demo app built using this client.

Documentation

You can find the detailed API documentation in GitHub repository.

Also, the web client tutorial contains a similar event driven client as we have here.
