Frequently Asked Questions
What is an AI voice SDK and how does it work?
An ai voice sdk (Software Development Kit) is a set of software tools, libraries, and documentation that allows developers to integrate real-time artificial intelligence voice changing capabilities directly into their applications or games. By utilizing advanced deep learning models, the SDK analyzes the user's incoming microphone audio, extracts the vocal characteristics, and maps them onto a target voice model in real time. On desktop, this process happens entirely on the local device to ensure maximum performance and a consistent 300ms latency. For real-time mobile voice changing, the player uses Dubbing Voice Changing Earbuds connected to a compatible phone. Developers can easily implement this technology to allow players to customize their vocal identity, enhancing immersion in multiplayer environments. It bridges the gap between complex AI voice modeling and simple, developer-friendly game engine integration.
How does the SDK deliver consistent 300ms latency during gameplay?
Our engineering team has optimized our proprietary voice transformation engine to deliver a consistent 300ms voice-changing latency. On desktop, this is accomplished by performing audio processing locally on the user's machine, eliminating the need to send audio data to external cloud servers. For real-time mobile voice changing, the Dubbing Voice Changing Earbuds deliver the experience on iPhone 15 and later, or Android phones with a USB-C port. This consistency is important for fast-paced multiplayer games where real-time communication can mean the difference between victory and defeat. Players will experience natural conversations with dependable real-time performance.
Will integrating this SDK impact my game's performance or frame rate?
We understand that game performance is a top priority for developers, which is why our SDK is designed to have an incredibly small footprint. The entire engine runs on just 2-3% CPU usage, ensuring that it does not interfere with your game's rendering, physics, or logic loops. Additionally, the local storage requirement is only about 300MB, making it easy to package with your game build without bloating the download size. We have thoroughly tested our SDK alongside major game engines like Unity and Unreal to guarantee optimal performance. Your players will enjoy high-fidelity voice transformation without experiencing any drops in frame rate or system responsiveness.
What platforms and game engines does the Dubbing AI SDK support?
The Dubbing AI SDK is built with cross-platform compatibility in mind, allowing you to deploy your game across multiple devices seamlessly. It offers native support and wrappers for major game engines including Unity, Unreal Engine, and custom C++ engines. The desktop app supports Windows and macOS, while the mobile app lets players record audio, apply voice changes for free, and then save the recording or send it to other apps. For real-time voice changing on a phone, players need to pair Dubbing Voice Changing Earbuds with an iPhone 15 or later, or an Android phone with a USB-C port. This wide platform coverage ensures that you can deliver immersive voice features to all of your players, regardless of their preferred gaming setup.
How secure is the SDK, and how does it handle player voice data?
Security and privacy are core pillars of the Dubbing AI platform, especially when dealing with sensitive biometric data like player voices. On desktop, voice transformation is processed locally on the player's device, meaning that raw audio data is never uploaded, stored, or transmitted to external servers. For real-time mobile voice changing, players pair Dubbing Voice Changing Earbuds with a compatible phone. This on-device approach eliminates the risk of external data exposure or interception. It also helps developers comply with strict global privacy regulations such as GDPR and CCPA regarding user data protection. You can confidently integrate our SDK knowing that your players' voice privacy is fully protected at all times.
Can we import custom cloned voices or create unique character voices?
Yes, our SDK fully supports custom AI voice cloning, allowing you to create exclusive vocal identities for your game's characters. Developers or players can upload short audio samples of a specific voice, and our system will generate a highly realistic AI model of that voice. These custom models can then be packaged directly into the SDK or streamed dynamically to players. This feature is perfect for creating unique NPC voices, branded promotional characters, or allowing players to craft their own custom vocal avatars. It provides unparalleled creative freedom to make your game's audio experience truly unique and memorable.
