Fixes #3731 espeak-ng and piper-phonemize are no longer built into sherpa-onnx. Text frontends are now: - **lexicon** — built in, no extra dependency - **phonemize** — phonemize outside sherpa-onnx (e.g. [piper-phonemize](https://github.com/csukuangfj/piper-phonemize)) and pass the result in. That library is GPL, so it stays optional: sherpa-onnx is GPL-free after this PR. ## API - `SherpaOnnxGenerationConfig` gains `phoneme_codepoints` and `tokens` (mutually exclusive alternatives to `text`) - `data_dir` on the TTS model configs is deprecated and ignored; the ABI slot is kept - all bindings updated: C/C++, Python, Java, Kotlin, Go, Rust, C#, Swift, Pascal, Dart/Flutter, node-addon, WASM, HarmonyOS

Test a Matcha English TTS model using lexicon-based phonemization
|
|
(no espeak-ng data, no external phonemizer needed).
|
|
|
|
If you don't want to use a lexicon, please see
|
|
test-offline-tts-matcha-en-phonemize.py which uses piper_phonemize instead.
|
|
|
|
Supported extra parameters in gen_config.extra (all optional):
|
|
- min_words_in_sentence, int, default 5.
|
|
Merge adjacent sentences if the number of words is less than this.
|
|
Each CJK character counts as one word; English words are space-separated.
|
|
- max_words_in_sentence, int, default 20.
|
|
Split a sentence into chunks if the number of words exceeds this.
|
|
Splits at punctuation or space boundaries.
|
|
- max_codepoints_in_sentence, int, default 200.
|
|
For the phoneme_codepoints path: split a phoneme sequence if it exceeds
|
|
this many codepoints. Splits at space boundaries.
|
|
- debug, int, default from model config.
