That’s it! One command. No configuration. No mess.

Step 2: Create hello.py

Copy this simple script:

  
#!/usr/bin/env python3
"""
Simple KittenTTS Demo
Make your computer say "Hello!"
"""

from kittentts import KittenTTS
import soundfile as sf

# Load the model (downloads automatically first time)
print("Loading TTS model...")
tts = KittenTTS("KittenML/kitten-tts-mini-0.8")

# Your message
message = "Hello! I am KittenTTS. I can speak any text you give me!"

# Generate speech
print(f"Generating: {message}")
audio = tts.generate(message, voice='Jasper')

# Save to file
sf.write('hello.wav', audio, 24000)
print("✅ Saved to hello.wav")

# Play it (macOS)
import os
os.system('afplay hello.wav')

Step 3: Run it!

python3 hello.py

First run: Downloads 80MB model (takes ~30 seconds) After that: Instant speech generation!

🎙️ Try Different Voices

KittenTTS has 8 voices built-in:

Test All Voices Script

  
#!/usr/bin/env python3
"""Test all 8 KittenTTS voices"""

from kittentts import KittenTTS
import soundfile as sf
import os

# Load model
tts = KittenTTS("KittenML/kitten-tts-mini-0.8")

# All available voices
voices = ['Jasper', 'Bella', 'Luna', 'Bruno', 'Rosie', 'Hugo', 'Kiki', 'Leo']

# Test message
message = "Hello! This is my voice."

# Generate audio for each voice
for voice in voices:
    print(f"🔊 Generating {voice}...")
    audio = tts.generate(message, voice=voice)

    filename = f'voice_{voice.lower()}.wav'
    sf.write(filename, audio, 24000)

    print(f"   ✅ Saved to {filename}")

print("\n🎉 Done! Test the voices:")
print("afplay voice_jasper.wav")
print("afplay voice_bella.wav")

💡 Cool Things You Can Do

1. Morning Greeting Script

  
from kittentts import KittenTTS
import soundfile as sf
import os
from datetime import datetime

tts = KittenTTS("KittenML/kitten-tts-mini-0.8")

# Get current time
hour = datetime.now().hour

# Choose greeting
if hour < 12:
    greeting = "Good morning! Time to start your day."
elif hour < 18:
    greeting = "Good afternoon! Hope you're having a great day."
else:
    greeting = "Good evening! Time to relax."

# Generate and play
audio = tts.generate(greeting, voice='Bella')
sf.write('greeting.wav', audio, 24000)
os.system('afplay greeting.wav')

2. Read Your Notifications

  
from kittentts import KittenTTS
import soundfile as sf
import os

tts = KittenTTS("KittenML/kitten-tts-mini-0.8")

def speak(text):
    """Speak any text"""
    audio = tts.generate(text, voice='Jasper')
    sf.write('/tmp/speak.wav', audio, 24000)
    os.system('afplay /tmp/speak.wav')

# Use it
speak("You have 3 new emails!")
speak("Build completed successfully!")
speak("Time for a coffee break!")

3. Accessibility Helper

  
from kittentts import KittenTTS
import soundfile as sf
import os

tts = KittenTTS("KittenML/kitten-tts-mini-0.8")

def read_file(filename):
    """Read text file aloud"""
    with open(filename, 'r') as f:
        text = f.read()

    # Read in chunks (better for long texts)
    sentences = text.split('. ')

    for sentence in sentences:
        if sentence.strip():
            audio = tts.generate(sentence + '.', voice='Luna')
            sf.write('/tmp/read.wav', audio, 24000)
            os.system('afplay /tmp/read.wav')

# Read any text file
read_file('article.txt')

🔧 Choose Your Model Size

KittenTTS has 4 model sizes. Pick based on your needs:

Model	Size	Quality	Best For
mini	80MB	⭐ Best	General use (default)
micro	41MB	Good	Faster generation
nano	56MB	Good	Small projects
nano-int8	25MB	Fair	Embedded devices

Use Smaller Model

  
# Faster, smaller model
tts = KittenTTS("KittenML/kitten-tts-micro-0.8")

# Smallest model (25MB!)
tts = KittenTTS("KittenML/kitten-tts-nano-0.8-int8")

📊 Performance

On M3 Pro (18GB RAM):

Model load: ~2 seconds
Generation: Real-time (1 second text = 1 second audio)
RAM usage: ~2-3GB
CPU: 20-30% (single core)

Even works on:

Raspberry Pi 4
Raspberry Pi 5
Old laptops
Any computer with Python!

🔍 Troubleshooting

“Module not found”

Make sure you’re using Python 3.11+:

python3 --version

If you have multiple Python versions:

python3.11 -m pip install https://github.com/KittenML/KittenTTS/releases/download/0.8/kittentts-0.8.0-py3-none-any.whl

First run is slow

First run downloads the 80MB model from HuggingFace. This is normal!

After the first run, it’s cached and loads instantly.

No sound

macOS: Use afplay:

  
os.system('afplay output.wav')

Linux: Use aplay or mpg123:

  
os.system('aplay output.wav')

Windows: Use start:

  
os.system('start output.wav')
