The error occurs because the gTTS engine received an empty text string from a subtitle line. This AssertionError: No text to send to TTS API is triggered when the software attempts to synthesize speech from a blank SRT entry.

Root cause analysis:
Your video's filename is in Vietnamese (Cô ấy được tái sinh...), but you have set the pronunciation language to Simplified Chinese and the target language to the same (发音语言和目标语言相同). Forcing faster-whisper to transcribe a Vietnamese audio track as Chinese AI speech will generate empty or garbage lines in the SRT file. Those empty lines are then passed directly to gTTS, causing the crash.

Steps to resolve:

Correct the language settings:
Set 发音语言 (source language) to vi (Vietnamese) to match the actual audio. If you want to translate it into Chinese, set 目标语言 to zh-cn. If you intend to keep the original language without translation, set both to vi.
Enable "清理已生成" (Clean generated files):
Since this error likely stems from a previously generated bad cache file, check the 清理已生成 box in the main interface. This ensures ASR and TTS run from scratch and don't reuse the corrupted empty subtitle file.
Switch the TTS channel:
gTTS (Free) requires a proxy in mainland China and is prone to failures. Use the built-in Edge-TTS (Free) instead, which is stable and supports all languages.
Manually inspect the SRT file (if the issue persists):
Go to your output folder (C:/Users/Admin/Videos/VideoTrans/Cô ấy...-mp4) and open the generated .srt file. Look for lines that contain only timestamps but no text. Delete those empty entries and re-run the task without checking "清理已生成" to preserve your manual fixes.
