Bat Spoken Language Identification
Android Quick Start

Platforms

• Android (5.0+, API 21+)

Requirements

• Picovoice Account and AccessKey
• Android Studio
• Android device with USB debugging enabled or Android simulator

Picovoice Account & AccessKey

Signup or Login to Picovoice Console to get your AccessKey. Make sure to keep your AccessKey secret.

Quick Start

Setup

1. Install Android Studio.

2. Include mavenCentral() repository in the top-level build.gradle. Then add the following to the app's build.gradle:

dependencies {
    // ...
    implementation 'ai.picovoice:bat-android:${LATEST_VERSION}' // replace with latest version
}

3. Add the following to the app's AndroidManifest.xml file to enable recording with an Android device's microphone:

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

Usage

Create an instance of Bat Spoken Language Identification:

import ai.picovoice.bat.*;

final String accessKey = "${ACCESS_KEY}"; // AccessKey obtained from Picovoice Console (https://console.picovoice.ai/)

try {
    Bat bat = new Bat.Builder()
        .setAccessKey(accessKey)
        .build(appContext);
} catch (BatException ex) { }

Process audio:

short[] getNextAudioFrame() {
    // .. get audioFrame
    return audioFrame;
}

while (true) {
    HashMap<BatLanguages, Float> languageScores = bat.process(getNextAudioFrame());
    if (languageScores != null) {
        // take action based on languageScores
    }
}

When done, release resources explicitly:

bat.delete();

Demo

For the Bat Spoken Language Identification Android SDK, we offer a demo application that demonstrates how to use the engine on real-time audio streams (i.e. microphone input).
