Android IDVoice sample application

The application was tested with VoiceSDK 4.0.0.

This sample application is intended to demonstrate the VoiceSDK voice verification and liveness capabilities:

• It provides a simple text-dependent enrollment and voice verification scenario: user enrolls with three entries of their voice to create a strong voiceprint. Then they can use the created voiceprint for voice verification. By enrolling for the second time user overwrites their voiceprint. Liveness result tells whether the speech is genuine or not.

• It provides simple text-independent enrollment and verification scenario: user enrolls with 10 seconds of their speech to create a strong voiceprint. By enrolling for the second time user overwrites their voiceprint. Liveness result tells whether the speech is genuine or not.

The application also demonstrates the way to validate user audio input by performing quality checks (SNR level, speech length, relative speech length and multiple speakers detection).

• Enrollment process can't get completed if quality checks are not met.

• Verification process can't get completed if quality checks are not met except for multiple speakers detection which is shown as a warning in liveness results if detected.

All source code contains commentary that should help developers.

Tips for voice verification process

• Do enrolls in quiet conditions. Speak clearly and without changing the intonation of your usual voice.

Please refer to IDVoice quick start guide, IDLive quick start guide and signal validation guide in order to get more detailed information and best practices for the listed capabilities.

Developer tips

• This repository does not contain VoiceSDK distribution itself. Please copy the java/voicesdk-aar-full-release.aar file from the IDVoice + IDLive Android package received from ID R&D to the voicesdk/ folder in order to be able to build and run the application.

• For x86 and x86_64 emulator builds poor performance is expected, even with KVM enabled. Also, as QEMU emulation is imperfect, you can see occasional crashes. Please use newer images to mitigate both of these problems.

• It is strongly advised to enable ABI splits so that only relevant of AAR native libraries is present in each apk, greatly reducing their size.

• Be careful:

  • all VoiceSDK classes that inherit from VoiceSdkNativePeer (most VoiceSDK classes) must be closed after using.
