TensorFlow Lite Audio Classification Android Demo

Overview

This sample will record audio on a physical Android device and attempt to classify those recordings. The supported classification models include YAMNET and a custom speech command model trained using TensorFlow's Model Maker. These instructions walk you through building and running the demo on an Android device.

The model files are downloaded via Gradle scripts when you build and run the app. You don't need to do any steps to download TFLite models into the project explicitly.

This application should be run on a physical Android device.

Build the demo using Android Studio

Prerequisites

  • The Android Studio IDE. This sample has been tested on Android Studio Bumblebee.

  • A physical Android device with a minimum OS version of SDK 23 (Android 6.0) with developer mode enabled. The process of enabling developer mode may vary by device.

Building

  • Open Android Studio. From the Welcome screen, select Open an existing Android Studio project.

  • From the Open File or Project window that appears, navigate to and select the tensorflow-lite/examples/audio_classification/android directory. Click OK.

  • If it asks you to do a Gradle Sync, click OK.

  • With your Android device connected to your computer and developer mode enabled, click on the green Run arrow in Android Studio.

Models used

Downloading, extraction, and placing the models into the assets folder is managed automatically by the download_model.gradle file.
