F5-Myanmar-TTS

🌟 What's New in v2

• Over 1 Million Updates: Pushed training from 569,780 steps (v1) to 1,025,604 updates (36 epochs) for significantly tighter phonetic alignment and tone clarity.
• 50% Smaller Model (FP16): Pruned weights down from 1.35 GB to 674 MB for 2x faster downloads and lower GPU VRAM consumption.
• Production-Grade Zero-Shot Voice Cloning: Natural conversational cadence, improved tone handling on conjuncts and Pāḷi loanwords, and zero cut-offs.
• Raw Checkpoints Available: Intermediate checkpoints (model_1020000.pt, model_1025000.pt, and model_last.pt) are included under checkpoints/ for developers wanting to continue fine-tuning.

⚡ Quickstart: Python Package (f5-myanmar-tts)

The easiest way to use this model is with the official PyPI package:

pip install --upgrade f5-myanmar-tts

Python (Just 3 lines):

from f5_myanmar_tts import MyanmarTTS

# Auto-downloads lightweight v2 FP16 model (~674MB) on first run
tts = MyanmarTTS()

# Generate Burmese speech
tts.speak(
    "လူသားတွေ အားလုံးကို အယုတ်အလတ်အမြတ်မရွေး ချစ်ခင်လေးစားပါ",
    output_file="speech.wav"
)

Voice Cloning (Clone any voice in 3–5 seconds):

tts.speak(
    text="ဒါကြောင့် အုံ့မှိုင်းနေတဲ့ ကောင်းကင်ကို အမိန့်ပေးပြီး မိုးကောင်းကင် တံခါးတွေကို ဖွင့်လိုက်တယ်",
    ref_audio="my_voice.wav",
    ref_text="အပြင် မသွားရလို့ စိတ်ညစ်နေပါတယ် မိုးတွေ တအား ရွာနေပါတယ်",
    output_file="cloned_speech.wav"
)
