Streaming Text to Speech

Pick a voice from the available catalog, request a streaming text-to-speech response for low-latency playback, and save the returned audio stream.

This example assumes using ElevenLabs; is in scope and apiKey contains your ElevenLabs API key.

using var client = new ElevenLabsClient(apiKey);

// Choose a voice to synthesize with.
var voices = await client.Voices.GetAllAsync();
var voice = voices.Voices[0];
const string text = "This audio is streamed for low-latency playback.";

Console.WriteLine($"Using voice: {voice.Name} ({voice.VoiceId})");
Console.WriteLine($"Input text: {text}");

// Request streaming speech audio.
using var streamedAudio = await client.TextToSpeech2.StreamAsync(
    voiceId: voice.VoiceId,
    text: text,
    modelId: "eleven_multilingual_v2",
    outputFormat: TextToSpeechStreamOutputFormat.Mp32205032);

// Persist the result to a local file.
await using var output = File.Create("streamed-output.mp3");
await streamedAudio.CopyToAsync(output);
Console.WriteLine($"Saved {output.Length} bytes to streamed-output.mp3");
