Frame-based, real-time voice AI pipeline framework for .NET. Inspired by Pipecat. Provides core abstractions: Frame, FrameProcessor, Pipeline, PipelineRunner.

WebSocket source and sink processors for the Voxa pipeline. Operates over any System.Net.WebSockets.WebSocket — works with ASP.NET Core, ClientWebSocket, and any host that surfaces a WebSocket.

Vendor-neutral STT and TTS abstractions for the Voxa pipeline. Defines ISpeechToTextEngine, ITextToSpeechEngine, and the generic SpeechToTextProcessor / TextToSpeechProcessor that any vendor engine plugs into.

Adapter that wraps any Microsoft.Agents.AI AIAgent as a Voxa FrameProcessor. Bridges transcribed user input into the agent and pumps streamed text + tool calls back into the pipeline.

Azure Speech Services STT and TTS engines for the Voxa pipeline. Implements ISpeechToTextEngine and ITextToSpeechEngine — pair with the generic SpeechToTextProcessor / TextToSpeechProcessor from... More information

OpenAI Whisper STT and OpenAI TTS engines for the Voxa pipeline. Implements ISpeechToTextEngine + ITextToSpeechEngine via the REST API — pair with the generic processors from Voxa.Speech.Abstractions.

Mistral text-to-speech engine for the Voxa pipeline. Implements ITextToSpeechEngine via Mistral's Voxtral-TTS audio API — pair with the generic TextToSpeechProcessor from Voxa.Speech.Abstractions.

ElevenLabs text-to-speech engine for the Voxa pipeline. Implements ITextToSpeechEngine via the streaming REST API — pair with the generic TextToSpeechProcessor from Voxa.Speech.Abstractions.

Composite STT+LLM+TTS+VAD processor for the Voxa pipeline framework, backed by the Azure Voice Live API. The same processor speaks Azure OpenAI Realtime and OpenAI Realtime by changing the endpoint.

ML-based voice activity detection for the Voxa pipeline using the Silero VAD ONNX model. Drop-in replacement for SilenceGateProcessor when energy-based filtering isn't enough — handles noisy environments and... More information

Fluent ASP.NET Core integration for Voxa. Provides MapVoxaVoice + a VoicePipelineBuilder so MAF-using apps can drop in a voice pipeline with a single fluent expression: app.MapVoxaVoice("/voice", v =>... More information

Composite STT+LLM+TTS+VAD processor for the Voxa pipeline framework, backed by the OpenAI Realtime API. Full-duplex streaming voice with server-side turn detection — the closest C# equivalent to Pipecat's... More information

Test helpers for Voxa pipelines: WAV file processors, capturing processors, in-memory transports.

OpenTelemetry tracing helpers for Voxa pipelines. Provides the TracingProcessor (drop in anywhere to emit per-frame Activity spans) on top of the public Voxa ActivitySource.

Azure Speech Services STT and TTS processors for the Voxa pipeline. Use as a granular alternative to the Voice Live composite when you need finer control or regional fallback (Voice Live is North America... More information

Local/offline speech-to-text for the Voxa pipeline using whisper.cpp (via Whisper.net). No API key, no network after the first-run model download — develop without cloud accounts, run zero-cost CI... More information

Local/offline high-quality text-to-speech for the Voxa pipeline using Kokoro-82M (Apache-2.0) on ONNX Runtime, in-process. No API key, no network after the first-run model download. The quality tier of Voxa's... More information
