Verify the sound behind the character
Seed-TTS-eval documents character-level scoring on Chinese text. A recognizer may infer the correct character from context even if a listener hears an unintended pronunciation. The v1.5 model card documents Pinyin controls. Use them to specify readings that a fluent reviewer has already approved. Seed-TTS-eval · v1.5 controls
A proposed Mandarin museum audio guide can include surnames, place names, and polyphones. Mark the expected reading, generate a baseline, and regenerate the flagged words with approved pronunciation input. Have the reviewer listen to the phrase in its full sentence, since natural stress may change when a word is isolated.
