When to use this model

  • Most general-purpose applications
  • When you want good quality without the full footprint of kitten-tts-mini
  • Server-side deployments with moderate storage or memory constraints
  • Default choice when you are unsure which model to start with
kitten-tts-micro is a good starting point for most projects. You can always switch to kitten-tts-mini if quality is not sufficient, or kitten-tts-nano if you need faster inference.

Usage

from kittentts import KittenTTS
import soundfile as sf

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

    "Welcome to Kitten TTS, the ultra-lightweight text-to-speech library.",
    voice="Jasper"
)
sf.write("output.wav", audio, 24000)
The model is downloaded from Hugging Face on first use and cached locally. Pass cache_dir to control where it is stored.
