How to Use AI Voice Changer for Real-Time Voice Modification?

An AI voice changer allows you to transform your voice in real-time, much like a skilled actor shifting between roles. It accurately replicates the tone, pitch, and rhythm of your chosen voice. The technology preserves your speech rate, emotions, and intonation, ensuring authenticity. You can effortlessly switch between different voices at any moment. With ultra-low latency, it guarantees smooth communication in any setting. Whether you’re chatting, streaming, or gaming, it elevates your experience. This feature adds a touch of creativity and fun to your conversations.

In this blog, we’ll show you how to integrate the AI voice-changing feature into your app bases on ZEGOCLOUD Voice Call SDK, making it easy to implement for real-time use.

Before You Begin

Before implementing the AI voice changing feature, please ensure:

• Contact ZEGOCLOUD technical support to apply for a trial and obtain a custom package with the AI voice changer feature.
• Log in the ZEGOCLOUD Admin Console, create a project, and get the AppID and AppSign of your project.
• Your project has integrated ZEGO Express SDK , and your project has implemented basic real-time audio features. For details, please refer to Quick Start.

Implementation Steps

Initialize the SDK

Check out the ZEGOCLOUD Voice Call Documentation Quick Start – Create the ZegoExpressEngine instance to learn how to initialize the ZegoExpressEngine SDK.

Log in

Create an AI Voice Changer

To create an AI voice changer, call the createAIVoiceChanger method. You can create only one instance at a time. If you create a second instance before calling the destroyAIVoiceChanger method to destroy the existing one, null will be returned.

// Create an AI voice changer instance.
aiVoiceChanger = ZegoExpressEngine.getEngine().createAIVoiceChanger();

To set event callbacks for the AI voice changer, call the ZegoAIVoiceChanger.setEventHandler operation.

// Set event callbacks for the AI voice changer.
aiVoiceChanger.setEventHandler(new IZegoAIVoiceChangerEventHandler() {
    @Override
    public void onInit(ZegoAIVoiceChanger aiVoiceChanger, int errorCode) {
        super.onInit(aiVoiceChanger, errorCode);
    }

    @Override
    public void onUpdate(ZegoAIVoiceChanger aiVoiceChanger, int errorCode) {
        super.onUpdate(aiVoiceChanger, errorCode);
    }

    @Override
    public void onGetSpeakerList(ZegoAIVoiceChanger aiVoiceChanger, int errorCode, ArrayList<ZegoAIVoiceChangerSpeakerInfo> speakerList) {
        super.onGetSpeakerList(aiVoiceChanger, errorCode, speakerList);
    }
});

To initialize the AI voice changer instance, call the ZegoAIVoiceChanger.initEngine operation.

// Initialize the AI voice changer instance.
aiVoiceChanger.initEngine();

The ZegoAIVoiceChanger.initEngine operation must be called before you call the startPublishingStream method.

Update the Changer

To update the instance, call the ZegoAIVoiceChanger.update operation. The first update will take a long time due to the large size of the instance file.

// Update the AI voice changer instance.
aiVoiceChanger.update();

Get the Timbre List.

To obtain the list of available timbres, call the ZegoAIVoiceChanger.getSpeakerList method.

The list will be returned in the IZegoAIVoiceChangerEventHandler.onGetSpeakerList callback.

// Obtain the list of available timbres.
aiVoiceChanger.getSpeakerList();

Apply the Timbre You Want

Call the ZegoAIVoiceChanger.setSpeaker method to specify a timbre from the list obtained.

If the timbre ID is set to 0, the original timbre is used.

// Specify a timbre.
int speakerID = 0; // The timbre ID.
aiVoiceChanger.setSpeaker(speakerID);

Destory the AI Voice Changer

Call the destroyAIVoiceChanger operation to destroy the instance and release resources, such as the microphone.

// Destroy the AI voice changer instance.
ZegoExpressEngine.getEngine().destroyAIVoiceChanger(aiVoiceChanger);
