Voice cracked when stream_batch is low. 声音在stream_batch低的时候有很多噪音

[faw21]

When setting stream=True with a low stream_batch (assume 1 or 2), even though it decreases latency to first audio chunk by a lot (~150ms on 4090), the audio is very noisy. I tried concatenate all generated audio chunks and play them together after stream finished, the noise still persisted. This is also true even when stream_batch is default (24), I can hear that the point between two concatenated audio chunks have a tiny distortion. Is this a fixable issue? thanks.

在流式输出时把stream_batch降到1或者2时可以减少很多latency，但是音质受到很大音响，播放音频时有很大的、持续的电流声，音调也比非流式输出时要低。另外，即使用default batch size 24，我仍然可以在音频与音频连接处听到一些杂音，请问这个问题是否可以解决？是什么原因引起的？谢谢。

这是流式输出的原理导致的，无法有效解决，目前已经将杂音影响降至最低，可参考#521
