常见问题 (3)
故障排除为什么Supertonic TTS生成的音频不完整，会出现单词缺失或重复的情况？
故障排除
为什么Supertonic TTS生成的音频不完整，会出现单词缺失或重复的情况？升级到Supertonic 3，可显著减少音频不完整、单词跳过和片段重复的问题。对于早期版本，重新生成音频可暂时解决该问题。在树莓派等资源受限设备上，建议使用较低质量设置以减少生成时间，并检查音频是否存在异常。
故障排除为什么Supertonic TTS会读错像'SDKs'这样的缩写词或者跳过单词？
故障排除
为什么Supertonic TTS会读错像'SDKs'这样的缩写词或者跳过单词？早期的Supertonic版本有时会误读缩写、跳过单词或产生不稳定的输出。请升级至专注于提升阅读稳定性并减少跳过单词的Supertonic 3。试用地址：https://huggingface.co/spaces/Supertone/supertonic-3
故障排除为什么Supertonic TTS在从长句子生成音频时会跳过或遗漏单词？
故障排除
为什么Supertonic TTS在从长句子生成音频时会跳过或遗漏单词？升级到Supertonic 3，它能提高阅读准确率并减少跳读。如果无法升级，则在将输入文本送入模型之前，先按标点符号（如破折号和分号）进行分割——这可以避免输入过长导致模型低估语音时长并漏掉单词。对于多个输出候选，只生成一个（零样本）并使用第一个文件，因为后续迭代更容易出现故障。
