Describe the bug PaddleSpeech-Server描述说语音识别服务支持pcm和wav两种格式，但输入pcm格式文件时，报以下错误：

raise LibsndfileError(err, prefix="Error opening {0!r}: ".format(self.name)) soundfile.LibsndfileError: Error opening <_io.BytesIO object at 0x7f9bc43d1b30>: Format not recognised. [2023-12-01 15:54:05,375] [ ERROR] - can not open the audio file, please check the audio file(<_io.BytesIO object at 0x7f9bc43d1b30>) format is 'wav'. you can try to use sox to change the file format. For example: sample rate: 16k sox input_audio.xx --rate 16k --bits 16 --channels 1 output_audio.wav sample rate: 8k sox input_audio.xx --rate 8k --bits 16 --channels 1 output_audio.wav

传递字段audio_format { "audio": "exSI6ICJlbiIsCgkgICAgInBvc2l0aW9uIjogImZhbHNlIgoJf...", "audio_format": "pcm", "sample_rate": 16000, "lang": "zh_cn", "punc": 0 }

wav和pcm格式传入punc参数都没用，没有补充标点符号

传递字段audio_format { "audio": "exSI6ICJlbiIsCgkgICAgInBvc2l0aW9uIjogImZhbHNlIgoJf...", "audio_format": "pcm", "sample_rate": 16000, "lang": "zh_cn", "punc": 0 }

我确认下："audio_format": "pcm"时，audio对应的是纯pcm载荷吧？因为如果携带的是wav载荷是没有问题的。而且我查看代码也只是对wav载荷处理，没有对纯pcm载荷的处理。

我试了下，punc的参数在wav的情况下一样是无效的... data = { "audio": base64_string, "audio_format": "wav", "sample_rate": 32000, "lang": "zh_cn", "punc": True }
