Overview

ElevenLabs provides high-quality, AI-powered text-to-speech with natural-sounding voices and multilingual support. This provider replaces the platform-native ITextToSpeechService registration with ElevenLabs cloud synthesis while still using platform-native audio playback.

Setup

NuGet Packages
Project File
MauiProgram.cs

Shiny.Speech.ElevenLabs

// In MauiProgram.cs
builder.Services.AddAudioPlayer();    // Platform-native audio playback (required)
builder.Services.AddElevenLabsTextToSpeech("your-api-key");

Or with a config object for additional options:

builder.Services.AddAudioPlayer();
builder.Services.AddElevenLabsTextToSpeech(new ElevenLabsConfig
{
    ApiKey = "your-api-key",
    DefaultVoiceId = "21m00Tcm4TlvDq8ikWAM",  // Rachel (default)
    ModelId = "eleven_multilingual_v2"           // default
});

Configuration

public record ElevenLabsConfig
{
    public required string ApiKey { get; init; }
    public string DefaultVoiceId { get; init; } = "21m00Tcm4TlvDq8ikWAM"; // Rachel
    public string ModelId { get; init; } = "eleven_multilingual_v2";
}

Property	Description	Default
`ApiKey`	Your ElevenLabs API key	(required)
`DefaultVoiceId`	Voice ID to use when none specified in `TextToSpeechOptions`	`21m00Tcm4TlvDq8ikWAM` (Rachel)
`ModelId`	The TTS model to use	`eleven_multilingual_v2`

Usage

Once registered, inject and use ITextToSpeechService exactly as you would with platform-native speech:

public class MyViewModel(ITextToSpeechService tts)
{
    async Task Speak()
    {
        // Simple speech with default voice
        await tts.SpeakAsync("Hello from ElevenLabs!");

        // List available ElevenLabs voices
        var voices = await tts.GetVoicesAsync();

        // Speak with a specific voice
        var voice = voices.FirstOrDefault(v => v.Name.Contains("Adam"));
        if (voice != null)
        {
            await tts.SpeakAsync("Hello!", new TextToSpeechOptions
            {
                Voice = voice,
                SpeechRate = 1.0f,
                Volume = 0.9f
            });
        }
    }
}

Combining with Platform STT

A common pattern is to use ElevenLabs for high-quality TTS while keeping platform-native STT:

builder.Services.AddSpeechToText();   // Platform-native STT
builder.Services.AddAudioPlayer();    // Platform-native playback
builder.Services.AddElevenLabsTextToSpeech("your-api-key");
