Voxa.Core

Core pipeline primitives for the Voxa real-time voice AI framework: Frame, FrameProcessor, Pipeline, PipelineRunner, AgentLoopProcessor.

Install

dotnet add package Voxa.Core --prerelease

Quickstart

using Voxa.Frames;
using Voxa.Pipelines;
using Voxa.Processors;

var pipeline = Pipeline.Build()
    .Source(new PipelineSource())
    .Then(new MyProcessor())
    .Sink(new PipelineSink());

await using var runner = new PipelineRunner(pipeline);
await runner.StartAsync();
await pipeline.Source.IngestAsync(new TextFrame("hello"));
await runner.WaitAsync();

What's included

  • Frame types under Voxa.Frames:
    • Data — AudioRawFrame, TranscriptionFrame, TextFrame, LlmTextChunkFrame, ToolCallRequestFrame, ToolCallResultFrame
    • Control — StartFrame, EndFrame, HeartbeatFrame, LlmTurnStartedFrame, LlmTurnEndedFrame, LlmUsageFrame, StatusFrame
    • System (priority-queued) — InterruptionFrame, Bot/UserStartedSpeakingFrame, Bot/UserStoppedSpeakingFrame, ErrorFrame
  • FrameProcessor base class with two-task drain — system frames (interruption, errors) preempt data frames via cancellation
  • Pipeline, PipelineBuilder, PipelineRunner — fluent composition + lifecycle owner
  • AgentLoopProcessor — framework-agnostic per-turn agent processor: data-loop / turn-worker split, frontend-tool TCS correlation, lifecycle hooks, token aggregation, per-turn isolation
  • IAgentTurnDriver — plug-point for any agent runtime (MAF, Semantic Kernel, custom). Voxa.Services.MicrosoftAgents ships the MAF driver.
  • VoxaActivities.Source — public ActivitySource named "Voxa" for OpenTelemetry

Zero dependencies beyond NUlid.

Status

Package Downloads
Voxa.Speech.Abstractions

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

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.
Voxa.Transports.WebSocket

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.
Voxa.Services.AzureVoiceLive

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.
Voxa.Audio.SileroVad

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 emits the same UserStartedSpeakingFrame / UserStoppedSpeakingFrame as Voice Live.
