  • Plain text
  • Basic punctuation for pauses
  • Newlines for natural breaks
  • [[slnc 500]] for 500ms silence
  • [[rate 200]] for changing speed mid-text
  • [[volm 0.5]] for changing volume mid-text
  • [[emph +]] and [[emph -]] for emphasis
  • [[pbas +10]] for pitch adjustment
• voice (optional): Voice to use (default: "Alex")
• rate (optional): Speaking rate in words per minute (default: 175, range: 1-500)
• background (optional): Run speech in background to allow further MCP interaction (default: false)

Advanced Features

1. Voice Modulation:

use_mcp_tool({
  server_name: "say",
  tool_name: "speak",
  arguments: {
    text: "[[volm 0.7]] This is quieter [[volm 1.0]] and this is normal [[volm 1.5]] and this is louder",
    voice: "Victoria"
  }
});

2. Dynamic Rate Changes:

use_mcp_tool({
  server_name: "say",
  tool_name: "speak",
  arguments: {
    text: "Normal speed [[rate 300]] now speaking faster [[rate 100]] and now slower",
    voice: "Fred"
  }
});

    text: "[[emph +]] Important point! [[emph -]] [[pbas +10]] Higher pitch [[pbas -10]] Lower pitch",
    voice: "Samantha"
  }
});

  arguments: { query: "quantum computing basics", count: 1 }
});

await use_mcp_tool({
  server_name: "say",
  tool_name: "speak",
  arguments: {
    text: searchResult.results[0].description,
    voice: "Daniel",
    rate: 150
  }
});

2. With YouTube Transcripts:

// Read a YouTube video transcript
const transcript = await use_mcp_tool({
  server_name: "youtube-transcript",
  tool_name: "get_transcript",
  arguments: {
    url: "https://youtube.com/watch?v=example",
    lang: "en"
  }
});

await use_mcp_tool({
  server_name: "say",
  tool_name: "speak",
  arguments: {
    text: transcript.text,
    voice: "Samantha",
    rate: 175
  }
});

3. Background Speech with Multiple Actions:

// Start long speech in background
await use_mcp_tool({
  server_name: "say",
  tool_name: "speak",
  arguments: {
    text: "This is a long speech that will run in the background...",
    voice: "Rocko (Italian (Italy))",
    rate: 69,
    background: true
  }
});

// Immediately perform another action while speech continues
await use_mcp_tool({
  server_name: "marginalia-mcp-server",
  tool_name: "search",
  arguments: { query: "parallel processing" }
});

4. With Apple Notes:

// Read notes aloud
const notes = await use_mcp_tool({
  server_name: "apple-notes-mcp",
  tool_name: "search-notes",
  arguments: { query: "meeting notes" }
});

if (notes.length > 0) {
  await use_mcp_tool({
    server_name: "say",
    tool_name: "speak",
    arguments: {
      text: notes[0].content,
      voice: "Karen",
      rate: 160
    }
  });
}
