Examples of What You Can Build With Switchboard
We believe real time voice is the next interface—and we’re making it radically easier to build solutions with it. Switchboard gives developers modular building blocks (think: LEGO for audio) to create new real-time experiences that combine things like music, livestreams, voice chat, AI voice agents, translation, or audio effects from reverb or noise cancellation to auto-tune and voice changers.
Instead of writing custom code to connect everything, you can snap together pre-built components for things like media playback, speech to text, text to speech, audio I/O, mixing and routing audio channels, webRTC, DSP effects, and more—allowing you to focus on designing innovative real time user experiences that can be made from these components rather than spending months in the weeds.
Whether you're working on a product in entertainment, voice AI, gaming, health, education, or any other industry, here are some examples of the types of things you can build with Switchboard:
Real-World Use Cases Built with Switchboard
Voice AI Agent
An AI voice assistant that can talk to you naturally, transcribe your words, and respond instantly—like a smart co-worker or virtual host inside your app.
Real-Time Language Translation
A two-way voice translator that listens, interprets, and speaks the translation out loud with minimal latency—whether for fun or customer service.
Watch Parties with Voice Chat
Let friends talk while watching videos or livestreams together, with perfectly synced playback auto-leveling volumes driven by voice detection.
Voice-Changing Avatars in Games
Give every character a unique voice in real time—turn your voice into a robot, alien, or action hero using audio effects and DSP.
Smart Music Player with Voice Control
A music player you can control by speaking. Create playlists from natural language or add hands-free controls.
Customer Support Voice Bot
Build a real-time voice bot that understands callers, responds using TTS, and routes conversations to the right place, and on any platform -- via the internet or a phone number.
Language Learning Buddy
A speaking partner that listens, helps you pronounce things correctly, and converses back in your target language.
Silent Disco / Group Music Sync
Sync music across devices so a group of users can listen together with zero lag—perfect for classes, events, or remote groups.
Podcast Co-Listening and Live Reactions
Let couples listen to podcasts while walking the dog while still able to talk through their headphones. Or connect a live audience—like Spotify meets Clubhouse.
On-Device Voice Agent with Wake Word
A privacy-first voice assistant that runs on-device, with wake-word detection and no cloud dependency.
Smarter In-Car Voice Assistants
An automotive voice agent that can not only talk to you, but that interfaces seamlessly with music, media, and communications.
AI-Controlled Livestream Host
A synthetic co-host for your livestreams that can answer questions, highlight comments, or cue music on command.
Team Voice Chat with Embedded Music
A persistent audio channel for remote teams with embedded music synchronized for all of you.
Voice-Controlled Game Streaming Overlay
A Twitch extension that responds to your voice—triggering overlays, soundboards, or in-game actions on stream.
Virtual Health Assistant for the Elderly
A friendly voice interface that can remind people to take medicine, answer health questions, and connect them to caregivers.
Audio Diary with Sentiment Detection
A personal audio journal that transcribes your thoughts and analyzes tone or emotional state over time.
Why This Matters
Building such use cases is normally time consuming and fraught with issues that compound as technical debt and poor user experience. Switchboard removes the friction from building real-time audio experiences. It contains things like:
📦 Pre-built audio modules (STT, TTS, effects, sync, etc.)
🔧 A flexible SDK for mobile, desktop, web, and embedded platforms
⚡️ Tools that help you innovate 10x faster
If you can imagine it, you can build it—block by block.
