(毕设踩坑记录)SpringBoot项目中采用Java、Python调用百度智能云接口实现文字转为语音。

登录百度智能云：百度智能云-智能时代基础设施

创建应用

根据个人需要填写相关内容即可

之后便可在管理应用界面看见自己创建的应用

 请记录下API Key和Secret Key

编写如下py代码

# coding=utf-8

import sys
import json
import os
import pygame
import time

# 保证兼容python2以及python3
IS_PY3 = sys.version_info.major == 3
if IS_PY3:
    from urllib.request import urlopen
    from urllib.request import Request
    from urllib.error import URLError
    from urllib.parse import urlencode
    from urllib.parse import quote_plus

# 替换你的 API_KEY
API_KEY = '*************'

# 替换你的 SECRET_KEY
SECRET_KEY = '*************'

TEXT = ""

              'client_id': API_KEY,
              'client_secret': SECRET_KEY}
    post_data = urlencode(params)
    if (IS_PY3):
        post_data = post_data.encode('utf-8')

    # 采用pygame后台播放mp3文件
    pygame.mixer.init()
    track = pygame.mixer.music.load('传入语音的位置\语音.mp3')
    pygame.mixer.music.play()
    time.sleep(10)
    pygame.mixer.music.stop()

vue将需要朗读内容ID传到后台我在SpringBoot中继承Mybatis所以通过ID查询对应的内容并将内容输出到txt文本中再调用python程序生成语音播放

//        写入文件
        File file = new File("路径*********");
        try {
            FileOutputStream outputStream = new FileOutputStream(file);
            byte content[] = trends_content.getBytes();
            try {
                outputStream.write(content);
                outputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

//        调用py
        Process proc;
        try {
            proc = Runtime.getRuntime().exec("python py文件路径");// 执行py文件
        } catch (IOException e) {
            e.printStackTrace();
        }

至此完成文本生成语音并播报

小白入门、能力有限、以此记录。
