Vietnamese Text-to-Speech and Speech-to-Text library with embedded models
Project description
VNTTS
Dự án tích hợp Vietnamese Text-to-Speech (TTS) và Speech-to-Text (STT):
- TTS:
nghitts/ Piper-compatible ONNX (giọng Banmai) - STT:
sherpa-onnx-zipformer-vi-2025-04-20

Cài đặt
python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
Quản lý model lớn (không dùng Git LFS)
1) Tách model (<= 80MB mỗi part)
python scripts/split_model.py models/banmai/banmai.onnx --chunk-size-mb 80 --write-checksum
Mặc định script tạo theo chuẩn:
banmai.part001banmai.part002- ...
2) Ghép model thủ công (nếu muốn)
python scripts/merge_model.py models/banmai/banmai.onnx --verify-checksum
# hoặc merge toàn bộ trong 1 thư mục
python scripts/merge_model.py models/asr/sherpa-onnx-zipformer-vi-2025-04-20
Auto-merge khi runtime (không cần user thao tác)
Khi gọi TTS hoặc STT, hệ thống tự động:
- phát hiện thiếu file
.onnx - tìm các file
.part* - ghép lại thành
.onnxtrước khi inference
Hỗ trợ cả 2 kiểu đặt tên part:
banmai.part001(hoặcbanmai.part1) ->banmai.onnxbanmai.onnx.part001(hoặcbanmai.onnx.part1) ->banmai.onnx
