Why a Voice‑First Landing Page?
Voice AI is no longer a novelty—users expect to hear products talk back, especially in SaaS and e‑commerce. A landing page that speaks can:
- Capture attention in seconds (audio is processed 5× faster than text)
- Build trust by sounding human‑like
- Boost conversions through guided demos and “listen‑to‑me‑explain” sections
In this post we’ll walk through building a simple, conversion‑focused landing page that leverages text‑to‑speech (TTS) and voice cloning. We’ll use ElevenLabs for high‑quality speech generation and Bluehost for a hassle‑free, affordable deployment.

- Front‑end: A clean landing page with a hero section, a “Hear the demo” button, and a short copy that explains the product.
- Backend: A lightweight Flask (or FastAPI) service that receives a text prompt, calls the ElevenLabs API, and returns the generated audio URL.
- Hosting: One‑click WordPress or a custom Node/Python app on Bluehost—the platform handles SSL, scaling, and a simple control panel, so you can focus on the AI part.
Step 1 – Set Up Your ElevenLabs Account
Head over to the ElevenLabs sign‑up page: https://try.elevenlabs.io/kr07zfuqn1bp. After confirming your email you’ll receive an API key. Keep it secret; we’ll load it from an environment variable.
# .env
ELEVENLABS_API_KEY=your_secret_key_here
ElevenLabs offers:
- High‑fidelity TTS (multiple voices, language support)
- Voice cloning (upload a few seconds of audio to create a custom voice)
- Streaming endpoints (ideal for real‑time demos)
Step 2 – Build the Backend (Python + Flask)
Create a new folder voice‑api and install dependencies:
python -m venv venv
source venv/bin/activate
pip install flask python-dotenv requests
app.py:
import os
from flask import Flask, request, jsonify
import requests
from dotenv import load_dotenv
load_dotenv()
API_KEY = os.getenv("ELEVENLABS_API_KEY")
BASE_URL = "https://api.elevenlabs.io/v1"
app = Flask(__name__)
def generate_speech(text, voice_id="EXAVITQu4vr4xnSDxMaL"):
url = f"{BASE_URL}/text-to-speech/{voice_id}"
headers = {
"xi-api-key": API_KEY,
"Content-Type": "application/json"
}
payload = {
"text": text,
"model_id": "eleven_monolingual_v1",
"voice_settings": {
"stability": 0.75,
"similarity_boost": 0.85
}
}
response = requests.post(url, json=payload, headers=headers, stream=True)
if response.status_code != 200:
return None, response.text
# Save to a temporary file and serve it
audio_path = f"static/{hash(text)}.mp3"
with open(audio_path, "wb") as f:
for chunk in response.iter_content(chunk_size=8192):
f.write(chunk)
return audio_path, None
@app.route("/api/speak", methods=["POST"])
def speak():
data = request.get_json()
text = data.get("text", "")
if not text:
return jsonify({"error": "Missing text"}), 400
audio_path, err = generate_speech(text)
if err:
return jsonify({"error": err}), 500
# Return a URL that the front‑end can play
return jsonify({"audio_url": f"/{audio_path}"})
if __name__ == "__main__":
app.run(host="0.0.0.0", port=5000, debug=True)
What’s happening?
- The
/api/speakendpoint receives a JSON payload like{"text":"Your copy here"}. - It forwards the text to ElevenLabs, using the default voice (you can swap
voice_idfor a cloned voice later). - The MP3 is saved under
static/and the URL is sent back to the client.
Step 3 – Front‑End: A Minimal Hero Section
Create index.html (or a simple WordPress page template if you’re on Bluehost’s WordPress hosting).
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>AI‑Powered Voice Demo</title>
<style>
body {font-family: Arial, sans-serif; text-align:center; padding:2rem;}
.hero {margin-top:3rem;}
button {padding:1rem 2rem; font-size:1.2rem; cursor:pointer;}
</style>
</head>
<body>
<section class="hero">
<h1>Meet Your New AI Assistant</h1>
<p>Press the button and hear a natural‑sounding voice explain what we do.</p>
<button id="playBtn">▶️ Hear the Demo</button>
<audio id="demoAudio" controls style="display:none;"></audio>
</section>
<script>
const btn = document.getElementById('playBtn');
const audio = document.getElementById('demoAudio');
btn.addEventListener('click', async () => {
btn.disabled = true;
btn.textContent = 'Generating…';
const response = await fetch('/api/speak', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: JSON.stringify({text: "Welcome to our platform! Our AI helps you turn ideas into reality with just a few clicks."})
});
const data = await response.json();
if (data.audio_url) {
audio.src = data.audio_url;
audio.style.display = 'block';
audio.play();
} else {
alert('Something went wrong: ' + (data.error || 'unknown'));
}
btn.disabled = false;
btn.textContent = '▶️ Hear the Demo';
});
</script>
</body>
</html>
Why this works for conversions
- Immediate feedback – Users hear the value proposition instantly.
-
Accessible – The
<audio>element provides a fallback for screen readers. - CTA‑ready – Place a “Get Started” button right after the audio finishes to capture the warm lead.
Step 4 – Deploy on Bluehost
If you already have a Bluehost account, you can spin up a PHP/Node/Python site in minutes:
- Log in to the Bluehost dashboard and click “Create Site”.
- Choose “Custom” → “Python (Flask)” (or the “WordPress” option if you prefer a theme).
- Upload your
voice‑apifolder via the File Manager or Git. - Set the environment variable
ELEVENLABS_API_KEYunder Settings → Environment Variables. - Hit “Deploy” – Bluehost handles the web server, SSL, and a free domain.
Bluehost’s one‑click WordPress installer also lets you embed the same HTML snippet into a page, while the Flask app runs side‑by‑side on the same account. It’s the easy, affordable way to get your voice AI project live without fiddling with Docker or VPS networking.
Step 5 – Optional: Add Voice Cloning
ElevenLabs lets you upload a short 5‑second sample to create a custom voice. After you’ve created the voice in the ElevenLabs dashboard, replace the voice_id in generate_speech:
voice_id = "your_custom_voice_id_here"
Now the demo will sound exactly like your brand’s founder or a professional narrator—great for building trust.
Performance Tips
| Tip | Why it matters |
|---|---|
| Cache audio URLs | Avoid calling the API for the same copy repeatedly; store the MP3 in a CDN or the static/ folder. |
| Pre‑warm the model | Send a short “warm‑up” request on server start to reduce the first‑call latency. |
| Compress responses | Enable gzip on Bluehost (default) to speed up HTML/CSS delivery. |
| Lazy‑load the audio element | Only load the <audio> tag after the user clicks, saving bandwidth on mobile. |
Final Thoughts
A voice AI landing page is a low‑effort, high‑impact experiment. By combining ElevenLabs’s cutting‑edge TTS with Bluehost’s straightforward hosting, you can get a production‑ready demo up in under an hour.
Pro tip: Run an A/B test—one version with the audio demo, one without. Track click‑through rates to quantify the conversion lift.
