The upstream Chatterbox README documents paralinguistic tags ([laugh],
[chuckle], [sigh], ...) as native to the Turbo family, and the vendored
Turbo pack passes them straight to the tokenizer -- it never parses them.
Our engine deleted them before the model saw them, so the feature looked
implemented and was inaudible.
* the text engine keeps a Turbo tag verbatim and records its name; on any
other pack the nine Turbo names stay literal text instead of being
swallowed as a voice name, and the run says so
* the v2 angle tokens are re-spelled for Turbo (<giggle> -> [giggle]) and
left untouched everywhere else
* generate_audio now builds one plan for every family, synthesises one
chunk per model call and joins the chunks; the classic path goes through
the engine too, which is what makes "[Alice]" open a character segment
* per-chunk seeds (seed + index) keep a chunked run reproducible without
giving every chunk the same prosody
* four appended widgets on ChatterboxTTS: enable_chunking,
max_chars_per_chunk, chunk_combination_method, silence_between_chunks_ms
* chunk boundaries prefer a sentence end and never land inside a tag
* Turbo's exaggeration is passed as 0.0: the family ignores it for
sampling and upstream warns about every non-zero value, once per chunk
