Voxa.Speech.Abstractions

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

Install

You typically don't install this package directly — install a vendor engine package (Voxa.Speech.Azure, Voxa.Speech.OpenAI, Voxa.Speech.ElevenLabs, Voxa.Speech.Mistral) and this package comes along as a transitive dependency.

If you're authoring a new vendor engine:

dotnet add package Voxa.Speech.Abstractions --prerelease

What it provides

public interface ISpeechToTextEngine : IAsyncDisposable
{
    Task StartAsync(CancellationToken ct);
    ValueTask WriteAudioAsync(ReadOnlyMemory<byte> pcm, CancellationToken ct);
    IAsyncEnumerable<TranscriptionResult> ReadTranscriptsAsync(CancellationToken ct);
    Task StopAsync();
}

public interface ITextToSpeechEngine : IAsyncDisposable
{
    Task StartAsync(CancellationToken ct);
    IAsyncEnumerable<byte[]> SynthesizeAsync(string text, CancellationToken ct);
}

Plus:

  • SpeechToTextProcessor — pipes AudioRawFrame into the engine, emits TranscriptionFrame.
  • TextToSpeechProcessor — drives the engine on TextFrame/LlmTextChunkFrame, emits BotStartedSpeaking + AudioRawFrame chunks + BotStoppedSpeaking.

Usage

using Voxa.Speech;

var pipeline = Pipeline.Build()
    .Source(new WebSocketAudioSource(ws))
    .Then(new SpeechToTextProcessor(new MyVendorSttEngine(opts)))
    .Then(new MicrosoftAgentsProcessor(agent))
    .Then(new TextToSpeechProcessor(new MyVendorTtsEngine(opts)))
    .Sink(new WebSocketAudioSink(ws));

Voxa.Speech.OpenAI

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.
Voxa.Speech.Azure

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

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.
Voxa.Speech.Mistral

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.
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.
