await liveClient.Subscribe(new EventHandler<ResultResponse>((sender, e) =>
{
    if (!string.IsNullOrEmpty(e.Channel.Alternatives[0].Transcript))
    {
        Console.WriteLine($"Transcript: {e.Channel.Alternatives[0].Transcript}");
    }
}));

// Connect to Deepgram
var liveSchema = new LiveSchema()
{
    Model = "nova-3",
};
await liveClient.Connect(liveSchema);

// Stream audio data to Deepgram
byte[] audioData = GetAudioData(); // Your audio source

await liveClient.Stop();
```

[See our API reference for more info](https://developers.deepgram.com/reference/speech-to-text-api/listen-streaming).

[See the Examples for more info](./examples/speech-to-text/websocket/).

## Flux - Conversational Speech Recognition (Preview)

> Flux support is currently in preview. The API surface may change in a future release.

Transcribe conversational audio with contextual turn detection using [Deepgram Flux](https://developers.deepgram.com/docs/flux/quickstart). Instead of interim/final results, Flux delivers `TurnInfo` events that track the turn lifecycle (`StartOfTurn`, `Update`, `EagerEndOfTurn`, `TurnResumed`, `EndOfTurn`) — ideal for voice agents that need to know when a speaker is done talking.

Flux accepts only two control messages (`CloseStream` and `Configure`); the classic streaming `KeepAlive`/`Finalize` messages do not apply.

```csharp
using Deepgram;
using Deepgram.Models.Flux.WebSocket;

// Initialize Library with default logging
Library.Initialize();

// Create Flux WebSocket client
var fluxClient = ClientFactory.CreateFluxWebSocketClient();
// Set "DEEPGRAM_API_KEY" environment variable to your Deepgram API Key

// Subscribe to TurnInfo events
await fluxClient.Subscribe(new EventHandler<TurnInfoResponse>((sender, e) =>
{
    if (e.EventType == TurnEvent.EndOfTurn)
    {
        Console.WriteLine($"Speaker finished: {e.Transcript}");
    }
}));

// Connect to Deepgram Flux (model is required)
var fluxSchema = new FluxSchema()
{
    Model = "flux-general-en",
    Encoding = "linear16",
    SampleRate = 16000,
    EotThreshold = 0.7,
};
await fluxClient.Connect(fluxSchema);

// Stream audio to Deepgram in ~80ms chunks (2560 bytes at 16kHz linear16)
byte[] audioChunk = GetAudioChunk(); // Your audio source
fluxClient.Send(audioChunk);

// Stop the connection (sends CloseStream and waits for the final results)
await fluxClient.Stop();
```

[See our API reference for more info](https://developers.deepgram.com/reference/speech-to-text/listen-flux).

[See the Examples for more info](./examples/speech-to-text/websocket/flux/) - including a [raw WebSocket version](./examples/speech-to-text/websocket/flux-raw/) that uses no SDK at all.

## Flux Text to Speech (Preview)

> Flux text-to-speech support is currently in preview. The API surface may change in a future release.

Synthesize speech with [Deepgram Flux](https://developers.deepgram.com/docs/flux/quickstart) TTS, available on two transports. Stream text in and receive synthesized audio out turn by turn over a WebSocket (built for voice agents), or generate a complete block of audio in a single batch (REST) request. Models are `flux-{voice}-{language}` (e.g. `flux-alexis-en`); an Aura model on this endpoint is rejected — use the classic Speak client for Aura voices.

Streaming sends exactly three client messages at Early Access — `Speak`, `Flush`, and `Close` (note: `Close`, not the listen client's `CloseStream`). Audio arrives as interleaved binary chunks alongside JSON control messages (`Connected`, `SpeechStarted`, `SpeechMetadata`, `Flushed`, `SessionMetadata`, `Warning`, `Error`).

```csharp
using Deepgram;
using Deepgram.Models.Flux.Speak.WebSocket;

// Initialize Library with default logging
Library.Initialize();

// Create Flux TTS WebSocket client
var speakClient = ClientFactory.CreateFluxSpeakWebSocketClient();
// Set "DEEPGRAM_API_KEY" environment variable to your Deepgram API Key

// Subscribe to synthesized audio chunks (raw bytes in the requested encoding)
await speakClient.Subscribe(new EventHandler<AudioResponse>((sender, e) =>
{
    if (e.Stream is not null) { /* play or persist e.Stream */ }
}));

// Connect to Deepgram Flux TTS (model is required)
var schema = new SpeakSchema()
{
    Model = "flux-alexis-en",
    Encoding = "linear16",
    SampleRate = 24000,
};
await speakClient.Connect(schema);

// Stream text into the active turn, then flush to generate the remaining audio
await speakClient.SendText("Sure, I can help you cancel your subscription.");
await speakClient.SendFlush();

// Stop the connection (sends Close and waits for the server to drain the audio)
await speakClient.Stop();
```

For batch (REST) synthesis of a complete block of text:

```csharp
using Deepgram;
using Deepgram.Models.Flux.Speak.REST;

var speakClient = ClientFactory.CreateFluxSpeakRESTClient();

// Synchronous: get the audio back and write it to a file
await speakClient.ToFile(
    new TextSource("Your appointment is confirmed for 3pm tomorrow."),
    "output.mp3",
    new SpeakSchema() { Model = "flux-alexis-en", Encoding = "mp3", BitRate = 48000 });

// Asynchronous: supply a callback URL and receive a request_id ack; the audio is
// delivered to your callback
// await speakClient.StreamCallBack(new TextSource("..."), "https://example.com/webhook",
//     new SpeakSchema() { Model = "flux-alexis-en" });
```

[See our API reference for more info](https://developers.deepgram.com/reference/text-to-speech).

[See the Examples for more info](./examples/text-to-speech/websocket/flux/) - and the [batch (REST) example](./examples/text-to-speech/rest/flux/).

## Voice Agent

Configure a Voice Agent.

```csharp
// Set "DEEPGRAM_API_KEY" environment variable to your Deepgram API Key
var agentClient = ClientFactory.CreateAgentWebSocketClient();

// Subscribe to key events
await agentClient.Subscribe(new EventHandler<ConversationTextResponse>
((sender, e) =>
{
    Console.WriteLine($"Agent: {e.Text}");
}));
await agentClient.Subscribe(new EventHandler<AudioResponse>((sender, e) =>
{
    // Handle agent's audio response
    Console.WriteLine("Agent speaking...");
}));

// Configure agent settings
var settings = new SettingsSchema()
{
    Language = "en",
    Agent = new AgentSchema()
    {
        Think = new ThinkSchema()
        {
            Provider = new ProviderSchema()
            {
                Type = "open_ai",
                Model = "gpt-4o-mini",
            },
            Prompt = "You are a helpful AI assistant.",
        },
        Listen = new ListenSchema()
        {
            Provider = new ProviderSchema()
            {
                Type = "deepgram",
                Model = "nova-3",
            },
        },
        // Option 1: Single Provider (Backward Compatibility)
        Speak = new SpeakSchema()
        {
            Provider = new ProviderSchema()
            {
                Type = "deepgram",
                Model = "aura-2-thalia-en",
            },
        },

// Option 2: Multiple Providers with Fallback Support
        // Uncomment the section below and comment out the single provider above
        // to use multiple TTS providers for enhanced reliability
        /*
        Speak = new SpeakSchema()
        {
            SpeakProviders = new List<SpeakProviderConfig>
            {
                // Primary provider: Deepgram
                new SpeakProviderConfig
                {
                    Provider = new ProviderSchema()
                    {
                        Type = "deepgram",
                        Model = "aura-2-zeus-en",
                    }
                },
                // Fallback provider: OpenAI
                new SpeakProviderConfig
                {
                    Provider = new ProviderSchema()
                    {
                        Type = "open_ai",
                        Model = "tts-1",
                        Voice = "shimmer",
                    },
                    Endpoint = new EndpointSchema()
                    {
                        URL = "https://api.openai.com/v1/audio/speech",
                        Headers = new Dictionary<string, string>
                        {
                            { "authorization", "Bearer {{OPENAI_API_KEY}}" }
                        }
                    }
                }
            }
        },
        */
    },
    Greeting = "Hello, I'm your AI assistant.",
};

// Connect to Deepgram Voice Agent
await agentClient.Connect(settings);

// Keep connection alive
await Task.Delay(TimeSpan.FromSeconds(30));

// Cleanup
await agentClient.Stop();
```

This example demonstrates:

- Setting up a WebSocket connection for Voice Agent
- Configuring the agent with speech, language, and audio settings
- Handling various agent events (speech, transcripts, audio)
- Sending audio data and keeping the connection alive

For a complete implementation, you would need to:

1. Add your audio input source (e.g., microphone)
2. Implement audio playback for the agent's responses
3. Handle any function calls if your agent uses them
4. Add proper error handling and connection management

## Text to Speech REST

Convert text into speech using the REST API.

```csharp
// Set "DEEPGRAM_API_KEY" environment variable to your Deepgram API Key
var speakClient = ClientFactory.CreateSpeakRESTClient();

var response = await speakClient.ToFile(
    new TextSource("Hello world!"),
    "output.wav",
    new SpeakSchema()
    {
        Model = "aura-2-thalia-en",
    });

Console.WriteLine($"Audio saved to: output.wav");
```

{
    // Handle the generated audio data
    Console.WriteLine("Received audio data");
}));

// Configure speak options
var speakSchema = new SpeakSchema()
{
    Model = "aura-2-thalia-en",
    Encoding = "linear16",

## Logging

This SDK uses [Serilog](https://github.com/serilog/serilog) to perform all of its
logging tasks. By default, this SDK will enable `Information` level messages and
higher (ie `Warning`, `Error`, etc.) when you initialize the library as follows:

```csharp
// Default logging level is "Information"
Library.Initialize();
```

To increase the logging output/verbosity for debug or troubleshooting purposes,
you can set the `Debug` level but using this code:

```csharp
Library.Initialize(LogLevel.Debug);
```

## Testing

### Unit Tests

Run:

```bash
   dotnet test Deepgram.Tests/Deepgram.Tests.csproj
```

### Integration Tests

See the [tests](./tests/) directory for integration tests and edge case validation
beyond the unit tests.

### Examples

See the [examples](./examples/) directory for working code samples for different
Deepgram SDK features.

## Backwards Compatibility

We follow semantic versioning (semver) to ensure a smooth upgrade experience.
Within a major version (like `6.*`), we will maintain backward compatibility
so your code will continue to work without breaking changes.
When we release a new major version (like moving from `5.*` to `6.*`),
we may introduce breaking changes to improve the SDK.
We'll always document these changes clearly in our release notes to help you
upgrade smoothly.

Older SDK versions will receive Priority 1 (P1) bug support only.
Security issues, both in our code and dependencies, are promptly addressed.
Significant bugs without clear workarounds are also given priority attention.
