📋 修改摘要
Bug 1：
torch.cat()空列表崩溃错误信息：
RuntimeError: torch.cat(): expected a non-empty list of Tensors
根因：当
LangSegmenter.getTexts()对某些文本返回空结果时，bert_list变为空列表，导致torch.cat([])崩溃。修复：在调用
torch.cat()前检查bert_list是否为空，若为空则创建零张量作为降级处理。Bug 2：BERT 特征与 Phones 长度不匹配
错误信息：
RuntimeError: The size of tensor a (44) must match the size of tensor b (45)
at non-singleton dimension 1
根因：BERT 特征序列长度与音素（phones）序列长度不一致（如 BERT 返回 45 个特征，但 phones 只有 44 个）。
修复：在返回前检测长度差异，使用线性插值放大或裁剪对齐。
