    春色将阑，莺声渐老，红英落尽青梅小。画堂人静雨蒙蒙，屏山半掩余香袅。
    密约沉沉，离情杳杳，菱花尘满慵将照。倚楼无语欲销魂，长空黯淡连芳草。

    首先安装python包

    pip3 install baidu-aip

    再注册百度AI得到相关参数

    https://ai.baidu.com/

    一、语音合成

    from aip import AipSpeech

APP_ID = '14446020'
API_KEY = 'GnaoLWrIiTKP10disiDHMiNZ'
SECRET_KEY = 'FYaMNBsH5NFsgWcRsyBfaHDV70MvvE6u'

#实例化AipSpeech对象
client = AipSpeech(APP_ID, API_KEY, SECRET_KEY)

#调用方法语音合成
result = client.synthesis("欢迎来到王者荣耀",
                          options={
                              "per": 1,
                              "spd": 9,
                              "pit": 9,
                              "vol": 15,
                          })
if not isinstance(result, dict):
    with open('auido.mp3', 'wb') as f:
        f.write(result)

    二、语音识别

    from aip import AipSpeech
import os

APP_ID = '14446020'
API_KEY = 'GnaoLWrIiTKP10disiDHMiNZ'
SECRET_KEY = 'FYaMNBsH5NFsgWcRsyBfaHDV70MvvE6u'

client = AipSpeech(APP_ID, API_KEY, SECRET_KEY)

def get_file_content(filePath):
    cmd_str = f"ffmpeg -y -i {filePath} -acodec pcm_s16le -f s16le -ac 1 -ar 16000 {filePath}.pcm"
    os.system(cmd_str)
    with open(f"{filePath}.pcm", 'rb') as fp:
        return fp.read()

res = client.asr(speech=get_file_content("auido.mp3"),options={
    "dev_pid":1536,
})

print(res["result"][0])

    这里用到一个格式转换的软件，百度地址：
    https://pan.baidu.com/s/1MadxSh-A0Pzo1Su_wKdktQ 提取码：x5xi
    固定的格式转换命令：（需要将bin文件添加环境变量，在cmd中执行）
    ffmpeg -y -i filePath -acodec pcm_s16le -f s16le -ac 1 -ar 16000 filePath.pcm

    三、短文本相似度

    from aip import AipNlp

APP_ID = '14446020'
API_KEY = 'GnaoLWrIiTKP10disiDHMiNZ'
SECRET_KEY = 'FYaMNBsH5NFsgWcRsyBfaHDV70MvvE6u'
client = AipNlp(APP_ID,API_KEY,SECRET_KEY)

ret = client.simnet("你今年几岁了？","多大年龄了？")
print(ret)

    {'log_id': 4545309161914786697, 'texts': {'text_2': '多大年龄了？', 'text_1': '你今年几岁了？'}, 'score': 0.742316} score 是两个测试的短文本相似度，一般大于0.72的两个短文本的意思是相似的句子！

    四、代码实现对接图灵

    import requests

def tuling_test(question):
    url = "http://openapi.tuling123.com/openapi/api/v2"
    data = {
        "reqType":0,
        "perception": {
            "inputText": {
                "text": question
            },
            "inputImage": {
            },
        },
        "userInfo": {
            "apiKey": "2f4e809b8b3049ce82a6b4787bad65bb",
            "userId": "wangjifei"
        }
    }

    return requests.post(url=url,json=data).json()

ret = tuling_test("心情不好")
print(ret.get("results")[0]["values"]["text"])

    五、简单实现人机交流

    • 基本步骤：
      用户录制音频---传入函数---格式转化---语音识别---匹配答案---语音合成---语音文件流写入文件---os执行文件---删除文件
    from aip import AipSpeech
from aip import AipNlp
from uuid import uuid4
import os
import requests
import time

APP_ID = '14446007'
API_KEY = 'QrQWLLg5a8qld7Qty7avqCGC'
SECRET_KEY = 'O5mE31LSl17hm8NRYyf9PwlE5Byqm0nr'

client = AipSpeech(APP_ID, API_KEY, SECRET_KEY)
nlp_client = AipNlp(APP_ID, API_KEY, SECRET_KEY)


def tuling_test(question):
    """接入图灵，为问题匹配答案"""
    url = "http://openapi.tuling123.com/openapi/api/v2"
    data = {
        "reqType": 0,
        "perception": {
            "inputText": {
                "text": question
            },
            "inputImage": {
            },
        },
        "userInfo": {
            "apiKey": "2f4e809b8b3049ce82a6b4787bad65bb",
            "userId": "wangjifei"
        }
    }
    ret = requests.post(url=url, json=data).json()
    return ret.get("results")[0]["values"]["text"]


def get_file_content(filePath):
    """音频的格式转换"""
    cmd_str = f"ffmpeg -y -i {filePath} -acodec pcm_s16le -f s16le -ac 1 -ar 16000 {filePath}.pcm"
    os.system(cmd_str)
    with open(f"{filePath}.pcm", 'rb') as fp:
        return fp.read()


def custom_reply(text):
    """根据问题得到相应的答案，可以通过短文本相似来自定义，也可以调用图灵问题库"""
    if nlp_client.simnet("你叫什么名字", text).get("score") >= 0.72:
        return "我不能告诉你"

    return tuling_test(text)


def learn_say(file_name):
    """机器人学说话"""

    # 语音识别成文字
    res = client.asr(speech=get_file_content(file_name), options={
        "dev_pid": 1536,
    })
    os.remove(f"{file_name}.pcm")
    text = res.get("result")[0]
    # 根据问题得到相关答案
    text1 = custom_reply(text)
    # 答案语音合成
    res_audio = client.synthesis(text1, options={
        "vol": 8,
        "pit": 8,
        "spd": 5,
        "per": 4
    })
    # 通过uuid 生成文件名
    ret_file_name = f"{uuid4()}.mp3"
    # 将生成的语音流写入文件中
    with open(ret_file_name, "wb") as f:
        f.write(res_audio)
    # 执行音频文件
    ret = os.system(ret_file_name)
    time.sleep(2)
    os.remove(ret_file_name)

if __name__ == '__main__':
    learn_say("auido.m4a")

        ret_file_name = learn_say(q_file_name)

        user_socket.send(ret_file_name)
