Integrating AI Voice with Notion and Productivity Tools

Why Voice‑First Productivity Makes Sense

We’re living in a world where you can ask a phone to book a meeting, write an email, or pull up a spreadsheet with just a few words. The same power is now available to the tools that sit at the core of our workflows—Notion, Todoist, Google Calendar, and more. By turning those text‑centric platforms into voice‑first experiences, you can:

• Save time: Speak a quick note instead of typing a sentence.
• Free your hands: Work while driving, cooking, or when your keyboard is out of reach.
• Reduce cognitive load: Let your brain focus on higher‑level decisions while the system handles the boilerplate.

If you’re a developer looking to add voice to your productivity stack, this guide will walk you through the most common patterns, with a focus on the ElevenLabs API, a top‑tier text‑to‑speech (TTS) service that also supports voice cloning.

The Building Blocks

For the purposes of this article we’ll focus on the ElevenLabs TTS and voice‑cloning features because of their high fidelity and flexible pricing. The same patterns will work with other providers if you prefer.

Getting Started with ElevenLabs

1. Sign up at the official site and grab your API key.
2. Install the SDK or use raw HTTP calls.
3. Read the docs for the available voices and parameters.

pip install elevenlabs

npm install elevenlabs

Tip: Store your API key in an environment variable (ELEVENLABS_API_KEY) to keep it out of your codebase.

Example 1 – Generating a Voice‑Over for a Notion Page (Python)

Below is a minimal script that:

1. Pulls the content of a Notion page.
2. Sends that content to ElevenLabs for TTS.
3. Saves the resulting MP3 to your local disk.

import os
import requests
from notion_client import Client
from elevenlabs import generate, set_api_key

# ---- Config ----
NOTION_TOKEN = os.getenv("NOTION_TOKEN")
PAGE_ID = "your-page-id-here"
ELEVENLABS_KEY = os.getenv("ELEVENLABS_API_KEY")

# ---- Setup ----
set_api_key(ELEVENLABS_KEY)
notion = Client(auth=NOTION_TOKEN)

# ---- Fetch Notion content ----
page = notion.pages.retrieve(page_id=PAGE_ID)
text = page.get("properties", {}).get("Title", {}).get("title", [{}])[0].get("plain_text", "")

# ---- TTS ----
audio = generate(
    text=text,
    voice="Rachel",          # Pick any voice from ElevenLabs catalog
    model="eleven_monolingual_v1"
)

# ---- Save MP3 ----
with open("notion_page.mp3", "wb") as f:
    f.write(audio)

print("✅ Audio saved!")

What you’ll learn

• How to authenticate with the Notion API.
• How to call ElevenLabs’ generate endpoint in Python.
• Basic error handling and file I/O.

Example 2 – Voice‑Command to Create a Todoist Task (JavaScript)

Here’s a quick demo that listens for a voice command, turns it into text, and then creates a new task in Todoist.

import { SpeechClient } from '@google-cloud/speech';
import { Todoist } from 'todoist';

const speechClient = new SpeechClient();
const todoist = new Todoist({ token: process.env.TODOIST_TOKEN });

async function transcribeAudio(file) {
  const [response] = await speechClient.recognize({
    audio: { uri: file },
    config: { encoding: 'LINEAR16', sampleRateHertz: 16000, languageCode: 'en-US' },
  });
  return response.results.map(r => r.alternatives[0].transcript).join(' ');
}

async function createTask(taskText) {
  await todoist.items.add({
    content: taskText,
    project_id: 'your-project-id',
  });
}

async function main() {
  const transcript = await transcribeAudio('recording.wav');
  console.log(`Heard: ${transcript}`);
  await createTask(transcript);
  console.log('✅ Task created!');
}

main().catch(console.error);

Pro tip: Replace the Google Speech API with Whisper or AssemblyAI if you prefer a purely open‑source solution.

Using curl for Quick Testing

If you’re in a hurry or want to prototype in the terminal, here’s a simple curl call that sends text to ElevenLabs and streams back an MP3.

curl https://api.elevenlabs.io/v1/text-to-speech/Rachel \
  -X POST \
  -H "xi-api-key: $ELEVENLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text":"Hello, world! This is a test voice.", "model_id":"eleven_monolingual_v1"}' \
  --output test.mp3

The resulting test.mp3 can be played back with any media player or uploaded to a Notion file attachment.

Voice Cloning – Make Your Bot Sound Like You

ElevenLabs also supports voice cloning, which is great if you want a personalized assistant that speaks in your own voice.

1. Record a short sample (ideally 30–60 seconds of clear speech).
2. Upload the sample to the API.
3. Generate a custom voice ID.

curl https://api.elevenlabs.io/v1/voice-clone \
  -X POST \
  -H "xi-api-key: $ELEVENLABS_API_KEY" \
  -H "Content-Type: multipart/form-data" \
  -F "audio=@your_sample.wav" \
  -F "name=MyCustomVoice" \
  -F "language=en"

The API will respond with a voice_id. Use this ID in subsequent generate calls to have your synthetic voice speak.

Hooking It All Together – A Simple Workflow

You can build this flow in any language, but a lightweight Node.js server with Express and the elevenlabs SDK is a great starting point.

const express = require('express');
const { generate } = require('elevenlabs');

const app = express();
app.use(express.json());

app.post('/voice-confirm', async (req, res) => {
  const { text } = req.body;
  const audio = await generate({
    text,
    voice: 'MyCustomVoice',
    model: 'eleven_monolingual_v1',
  });

  res.set('Content-Type', 'audio/mpeg');
  res.send(audio);
});

app.listen(3000, () => console.log('Voice server listening on port 3000'));

Security & Best Practices

• Keep API keys secret: Use environment variables and a secrets manager.
• Rate limits: ElevenLabs imposes limits; cache repeated requests if possible.
• Privacy: Never send sensitive data to third‑party services unless you’re sure they comply with your company’s data‑handling policies.
• Testing: Use unit tests to cover the audio generation pipeline; mock external calls with libraries like nock.

Deploying Your Voice Assistant

• Docker: Bundle your code, dependencies, and environment variables into a single container.
• Serverless: Platforms like Vercel or Netlify Functions can host the lightweight API endpoints.
• Edge: If latency matters, consider deploying the inference step closer to the user with Cloudflare Workers.

Recap & Next Steps

You now have:

• A solid understanding of how TTS, speech‑to‑text, and voice cloning fit together.
• Practical code snippets in Python, JavaScript, and raw curl.
• A roadmap for integrating voice into Notion, Todoist, Google Calendar, and beyond.

The key to a great voice‑first experience is iteration: start small, gather user feedback, and expand the feature set.
