AI Summary

v4.12 introduces updated AI models for speech recognition, including Nemotron-3.5-asr-0.6b and Parakeet TDT, while removing specific subtitle processing features. It also changes the LLM logic from re-segmentation to correction and optimizes the VAD algorithm.

Key Highlights

New ASR models: Replaced Parakeet Japanese with Nemotron-3.5-asr-0.6b and added Parakeet TDT to HuggingFace.
LLM Logic Update: Changed 'Re-segmentation' to 'Correction' (DeepSeek default).
Secondary Recognition: Fixed to use faster-whisper with large-v3-turbo.
UI/UX: Added 'Automatic detection' for audio language and independent language display for 80 languages.
Performance: Optimized VAD segmentation algorithm and translation prompts.

Breaking Changes

Removed 'LLM重新断句' (LLM Re-segmentation) feature.
Removed 'whisper预分割音频' (Whisper Pre-segment Audio) option.
Removed '合并邻近短字幕' (Merge Nearby Short Subtitles) option.
Secondary recognition channel changed to `faster-whisper`.

New Features

Support for `Nemotron-3.5-asr-0.6b` model supporting Japanese and 40+ languages.
Support for `nvidia/parakeet-tdt-0.6b-v3` model via HuggingFace ASR.
Added 'Automatic detection' option in video translation audio language dropdown.
Independent display of 80 available languages for transcription/synthesis/translation.
New 'LLM Correction AI Channel' setting available in advanced options.
