speech_recognition --- 语音识别模块

speech_recognition 模块的主要功能与函数

功能相关函数

speech_recognition.start(server, language)

启动语音识别服务，参数：

• server 服务器名称
• language 识别的语言

speech_recognition.get_error_code()

获取结果数据的错误码。返回值对应结果如下：

• 0 : 正确返回
• 3300： 语音输入参数不正确
• 3301：语音数据不清晰
• 3302：鉴权失败
• 3303：原始音频或者服务端问题
• 3304：用户请求超限(QPS)
• 3305：用户请求超限(pv-日请求量)
• 3307: 服务端问题
• 3308：音频数据过长
• 3309：音频数据异常
• 3310：音频文件过大
• 3311：采样率错误
• 3312：音频格式错误
• 3333：未知错误
• 3334：响应超时

speech_recognition.get_error_message()

获取错误的具体信息，字符串类型。

speech_recognition.get_result_code()

获取识别的结果,如果发生错误或者超时，返回空字符串。

speech_recognition.get_sn_code()

获取语音数据唯一标识，由服务器系统内部产生。

speech_recognition.get_all_respond()

获取语音识别结果，包含整个回复信息，如错误信息等
