Build voice apps effortlessly
Simplify voice and audio app development with our cross-platform SDK and no-code editor.
WE WORK WITH
Switchboard is useful for projects needing:
Voice control; voice agents & conversational AI; voice and video chat; language translation or interpretation; voice changers, cloning, and other effects; music, podcast, and video players; streaming & real-time broadcasts; karaoke & other interactive media; any real time voice or audio technology;
It is especially useful for projects that combine these.
Switchboard also includes a no-code editor: to build real time voice and audio workflows and deploy instantly to iOS, Android, macOS, Windows, Linux, and more.
Get to market faster
The Switchboard SDK saves time from prototyping through production and provides lasting flexibility. It's especially useful for products with that are cross-platform or have multiple voice and audio features.
Who is Switchboard designed for?
AI Agent and Voice AI solutions developers
Real Time Communications (RTC) applications
Music and social app developers
R&D / ML / AI teams looking to commercialize
Hardware projects like headphones, speakers, wearables, etc.
Pro audio industry - hardware and software
Apps & SDKs with voice, VoIP, media players, and other audio features
Product managers looking for a no code prototyping tool (Switchboard Editor)
See Use Cases in main menu for more details .
What does it do?
Switchboard is a modular audio framework incorporating a large library of audio nodes AudioNode. These nodes can easily be put together into audio graphs AudioGraph. Switchboard passes these graphs into natively compiled C++ code that runs fast, across multiple platforms including iOS, Android, Mac, Windows, web, and embedded platforms.
Audio graphs can be defined in JSON or native languages, making them easy to build while providing complete flexibility at runtime.
Switchboard also has a visual (no-code) node-based editor, the Switchboard Editor, which generates JSON automatically for rapid configuration of audio graphs that can easily be designed and tested in the browser and deployed to many target platforms.
It also allows you to tune parameters for each node or change the audio graph at runtime, rapidly speeding up development cycles.
What are audio nodes?
Audio nodes are essentially containers that process audio and include a wide range of functions such as:
speech-to-text (STT)
text-to-speech (TTS)
large language models (LLM)
real time language translation / interpretation
voice effects and voice changers
voice control for hands-free
music & media players
music generation
voice or audio streaming
voice and video calling
the ability to mix and split audio streams
voice detection and auto-ducking
DSP effects for media projects
sound separation
noise and echo reduction
Switchboard also includes extensions to many popular third party audio tools, both open and closed source. This includes nodes we've wrapped to run fully offline across multiple platforms, as well as commonly used APIs and SDKs.
Moreover, if an audio tool you want to use isn't already in our library, our Bring Your Own Node framework gives you the flexibility to connect anything to your Switchboard audio graph. This makes Switchboard the ideal starting point for any voice or audio project.
We are building an unbiased ecosystem in which developers can easily assemble audio graphs using nodes from any provider.
Audio technology developers can also bring their own technologies to Switchboard -- for private use or as publicly available nodes. Moreover, Switchboard can save you from having to build your own SDK.
Why should I use it?
Whether you’re using it for a single node such as speech-to-text or a voice changer, or stringing multiple nodes together, Switchboard will:
make it faster and easier to build, test, experiment, and get to market
make it easier to maintain and make changes later
save time and money
drive new revenue and growth by simplifying the addition of new features
How much does it cost?
Switchboard has a free tier up to 20K activations and Commercial Licenses available thereafter.
