在aspeak中调用ssml_to_speech_async时发生不规则运行时错误

Question

在python中的aspeak中调用SpeechToFileService实例的ssml_to_speech_async时发生RuntimeError。

这个错误似乎是随机发生的。即使args和环境完全相同，也不会每次都发生。有时，当我第二天重新启动计算机或进行测试时，错误会持续数小时。

这个错误似乎无法通过try捕捉到。

我已经搜索了错误代码、内存地址，但没有类似的帮助。

这是回溯文本(内存地址00007FFE37F772C4、00007FFE37FC76A8、00007FFE37FC87A8每次都是固定的。(

我称之为ssml_to_speech_async的代码

from aspeak import SpeechToFileService,AudioFormat,FileFormat
provider=None
fmt=AudioFormat(FileFormat.MP3,-1)
def init():

provider=SpeechToFileService(locale="zh-CN",audio_format=fmt)

在github上Issue的帮助下，我发现问题是文件名中有特殊字符。例如，char/。

如果有人遇到此错误，请尝试使用此正则表达式来替换以下字符：[*/\|<>? :.'"!]

然而，它可以解决这个问题，但其他一些字符可能会被替换，比如(空间(
