语音识别结果完全不对，录制音频稍大点就无法识别

使用贵司语音识别功能的录音识别功能，识别结果完全无法满足我们这边的要求，且稍大点音频无法进行识别，麻烦帮忙查看下，我这边可以提供taskid
识别失败：{"enable_callback":false,"error_message":"RECOGNIZE_FAILED","id":"26f3d6720cd7447e8a066d09c268b3a2","status":"FAILED","status_code":408}
失败结果差的:{"biz_duration":36246,"enable_callback":false,"id":"283709a0378e4325be981e52b1466768","result":[{"begin_time":0,"channel_id":0,"emotion_value":7.0,"end_time":36246,"silence_duration":0,"speech_rate":43,"text":"哎嗯啊嗯啊嗯嗯嗯嗯嗯嗯，an嗯，哎呀呃呃，哎呀嗯嗯嗯"},{"begin_time":0,"channel_id":1,"emotion_value":7.0,"end_time":36246,"silence_duration":0,"speech_rate":34,"text":"哎嗯啊嗯啊嗯嗯嗯嗯嗯嗯哎呀呃呃，哎呀嗯嗯嗯"}],"status":"SUCCEED"}
