YouTube Shorts with Kitten TTS

Why Kitten TTS for Shorts?

• Quick generation (under 1 second per clip)
• 8 voices for variety across different Shorts
• Speed control for fast-paced delivery
• Batch processing for daily content
• Free -- no per-video costs

Example: Fast Shorts Script

from kittentts import KittenTTS
model = KittenTTS("KittenML/kitten-tts-micro-0.8")

# Shorts need faster pace
model.generate_to_file(
    "This one trick will change how you edit videos forever!",
    "hook.wav", voice="Kiki", speed=1.3
)

model.generate_to_file(
    "Most editors waste hours on this. Here is the fix in 30 seconds.",
    "body.wav", voice="Jasper", speed=1.4
)

model.generate_to_file(
    "Follow for more editing tips! Drop a comment if this helped.",
    "cta.wav", voice="Rosie", speed=1.3
)

Best Practices for Shorts

• Hook first: Start with the most engaging line in the first 3 seconds
• Fast delivery: Use speed 1.3-1.5 for Shorts pacing
• Kiki or Rosie: Best voices for high-energy short-form content
• Caption sync: Generate audio first, then match captions to timing
