常见问题

1. ChatTTS 需要多少 VRAM？推理速度如何？

   • 对于 30 秒的音频剪辑，至少需要 4GB 的 GPU 内存。该模型在 4090 GPU 上可以生成大约每秒约 7 个语义标记对应的音频。实时因子（RTF）约为 0.3。

2. 我遇到了模型稳定性问题，比如多说话者问题或音频质量差的情况。有什么建议吗？

   • 这些问题在像 ChatTTS 这样的自回归模型中很常见。完全避免它们可能有挑战性。您可以尝试生成多个样本以找到合适的结果。

3. 除了控制笑声，还有其他可以控制的元素吗？我们可以管理其他情绪吗？

   • 在当前发布的模型中，唯一的令牌级控制单元是 [laugh]、[uv_break] 和 [lbreak]。未来版本可能会包括具有额外情绪控制功能的模型。
