"""Cossim debug : C++ qwen-tts vs Python Qwen3-TTS on the Voice Clone Mode B
|
|
(ICL) path.
|
|
|
|
Inputs (relative to CWD = tests/) :
|
|
../examples/prompt.txt target text fed to both pipelines
|
|
../examples/freeman.wav reference audio for cloning
|
|
../examples/freeman.txt transcript of the reference audio
|
|
|
|
Default mode is greedy on both sides, non_streaming_mode=False which is
|
|
the ICL branch upstream : text + codec streams are aligned to the codec
|
|
length, the shorter one padded with tts_pad / truncated as needed.
|
|
|
|
Cote Python the speaker embedding is captured directly via
|
|
model.extract_speaker_embedding, and the reference codec frames via
|
|
model.speech_tokenizer.encode. Both intermediates land as spk-emb.bin
|
|
and ref-codes.bin and are compared against the C++ side dumps emitted
|
|
by pipeline-tts.cpp when --ref-wav and --ref-text are set.
|
|
|
|
Dumps land in cpp/clone/ (C++) and python/clone/ (Python).
