    Native SwiftUI voice app for iOS running Pipecat in embedded Python with Apple Foundation Models and local speech synthesis.

    About pipecat-build-ios

    A native SwiftUI voice app running Pipecat directly on-device in embedded Python on the iPhone. It orchestrates Apple Speech recognition, Apple Foundation Models for text generation, and PocketTTS via FluidAudio for local speech synthesis, operating completely offline with zero backend server dependencies.

    For the Non-Technical Reader

    Imagine having a fully capable, real-time AI conversational assistant that lives entirely inside your iPhone—working seamlessly without internet connectivity or external servers. Instead of sending your voice audio to remote datacenters, the app handles listening, reasoning, and speaking right on your physical device. This delivers instantaneous responses, total privacy, and eliminates ongoing server infrastructure costs.

    For the Technical Reader

    • Architecture: Embedded Python 3.13 execution environment running Pipecat orchestration directly within a native SwiftUI iOS app context.
    • Voice Pipeline: Local Speech-to-Text via Apple Speech, on-device LLM reasoning using Apple Foundation Models, and local TTS powered by PocketTTS via FluidAudio (featuring 26 bundled stock voices).
    • Audio Engine: Unified capture and playback engine integrated with Apple echo cancellation, supporting full-duplex conversational flows with instant interruption handling and acoustic speech confidence filtering via Apple SoundAnalysis.
    • UI & Graphics: Responsive visual orb driven by a bundled Metal shader reacting to 20 ms audio windows, complete with native glass controls, Dynamic Type, VoiceOver, and Reduce Motion support.
    • Hardware & Build Requirements: Xcode 26+, macOS, and an Apple Intelligence-capable iPhone running iOS 26 or later (or Apple silicon simulator target).

    Why It Matters

    This repository demonstrates a paradigm shift toward edge-native voice agents. By bringing full framework orchestration like Pipecat on-device, developers can eliminate server cost-per-minute, guarantee zero data leakage for privacy-sensitive applications, and achieve ultra-low latency conversational interfaces without cloud vendor lock-in.

    The "Voice AI Space Lab" Idea

    Build an off-grid field exploration assistant for wilderness medics or marine researchers. Running entirely offline on an iPhone, the assistant can provide hands-free voice guidance through emergency procedures, log voice notes, and answer protocol queries deep in zero-connectivity environments.
