CasCap.Api.Voice.Testing

Canned speech-to-text and text-to-speech clients for testing code built on CasCap.Api.Voice without a speech backend.

Installation

dotnet package add CasCap.Api.Voice.Testing

Reference it from test projects only. Its only direct package dependency is the core Voice package; see the package dependency graph.

Test Clients

The Voice pipelines depend on the Microsoft.Extensions.AI ISpeechToTextClient and ITextToSpeechClient contracts. These fakes stand in for a real provider, so a consumer can exercise transcription, synthesis and its own orchestration deterministically. There is no network, audio tooling or credential involved.

Target frameworks: net10.0, net11.0

Public Surface

All types live in the CasCap.Fakes namespace.

Type Behaviour
FakeSpeechToTextClient Returns Transcript. It counts Requests, fails with Failure when set, and waits on Gate when set, so a test can observe work that is still in flight.
FakeTextToSpeechClient Returns Audio with MediaType (Ogg Opus by default). It counts Requests, records LastText, and fails with Failure when set.

The default synthesis bytes are only the four-byte OggS signature, not playable audio. Supply appropriate synthetic content when the consumer validates or decodes its result.

Usage

Replace the provider client before the Voice pipeline is resolved:

using CasCap.Fakes;
using Microsoft.Extensions.AI;
using Microsoft.Extensions.DependencyInjection;

#pragma warning disable MEAI001
var stt = new FakeSpeechToTextClient { Transcript = "synthetic transcript" };
var tts = new FakeTextToSpeechClient();

services.AddSingleton<ISpeechToTextClient>(stt);
services.AddSingleton<ITextToSpeechClient>(tts);
services.AddSpeechToText();
services.AddTextToSpeech();
#pragma warning restore MEAI001

services is the test host's IServiceCollection. The provider interfaces are experimental upstream, so the example scopes that compiler diagnostic to the registration code.

AddSpeechToText and AddTextToSpeech register their provider clients with TryAdd. A fake registered before them therefore takes precedence, and so does a later plain AddSingleton. Replacing a provider does not bypass media validation or synthesis policy: supply valid audio and enable a reply mode when testing the full pipelines.

See the core package usage for the application-facing contracts.
