Detailed Usage

synthesize▶

Convert a string of text into speech and play it.

use_mcp_tool({
  server_name: "text_to_speech",
  tool_name: "synthesize",
  arguments: {
    text: "Hello, world! This is a test."
  }
});

stream▶

Stream synthesized audio in real-time as it's generated.

use_mcp_tool({
  server_name: "text_to_speech",
  tool_name: "stream",
  arguments: {
    text: "This is a streaming test to demonstrate real-time audio synthesis."
  }
});

set_engine▶

Select the TTS engine to use for speech synthesis.

use_mcp_tool({

Common Use Cases

1. Voice-Enabled AI Assistants

Provide voice output for AI assistants and chatbots.

// Let the assistant speak its response
use_mcp_tool({
  server_name: "text_to_speech",
  tool_name: "synthesize",
  arguments: {
    text: "I'm sorry, I didn't understand that. Could you please rephrase?"
  }
});

2. Accessibility

Make applications more accessible by providing audio versions of text content.

// Read the content of an article aloud
use_mcp_tool({
  server_name: "text_to_speech",
  tool_name: "synthesize",
  arguments: {
    text: articleContent
  }
});

3. Real-Time Notifications

Create audible notifications for events in your applications.

// Announce a new message
use_mcp_tool({
  server_name: "text_to_speech",
  tool_name: "synthesize",
  arguments: {
    text: "You have a new message from Jane."
  }
});
