Yes, if you need a KugelAudio TTS client or local turn detection for conversational AI. The core SDK is lightweight with minimal dependencies and active maintenance. The optional turn-detection extra adds real value for voice applications but requires Python 3.11+, Hugging Face access, and roughly 1.55 GiB of model runtime. No known security vulnerabilities.

Before you install
- Requires a valid KugelAudio API key.
- Turn detection extra requires Python 3.11 or newer and Hugging Face authentication for the private model repository.
- Low friction: pure Python wheel with only httpx and websockets as runtime dependencies.

What it is and what it does
KugelAudio is the official Python client for the KugelAudio text-to-speech API, handling speech synthesis via WebSocket streaming. The core SDK requires only httpx and websockets, making it lightweight to install. It provides a simple interface to generate audio from text using specified model IDs and save the output to files.
An optional turn-detection extra adds local, CPU-based conversation endpoint detection using ONNX Runtime and PyTorch. This feature downloads a version-pinned model bundle from Hugging Face, verifies SHA-256 checksums, and runs inference locally without network calls after the initial model cache. It's designed for latency-sensitive voice applications—particularly LiveKit Agents integrations—where you need to detect when a user has finished speaking. The turn detector supports multiple languages and provides detailed decision reasoning, including incomplete-turn timeouts and barge-in handling for overlapping speech.
Use it for
- Generate speech from text in a web or mobile backend, streaming audio over WebSocket to reduce latency.
- Build a conversational voice agent that detects when users finish speaking using local turn detection without API round-trips.
- Integrate KugelAudio TTS into a LiveKit Agents application with manual turn handling and configurable silence thresholds.
- Implement a voice interface where you need to balance synthesis quality with low-latency streaming and local endpoint detection.
- Run turn detection offline after caching the model, suitable for edge deployments or privacy-sensitive applications.
