Python实现百度API文字转语音，让你的代码更智能化

准备工作

1、首先需要去百度智能云注册账号，官网：httPs://cloud.bAIdu.com/

2、登陆进入百度语音，领取免费资源

3、创建应用，记下自己的 APIkey和 Secret Key写入代码对应的位置

python示例代码

# coding=utf-8

import sys

import json

# 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

else:

import urllib2

from urllib import quote_plus

from urllib2 import urlopen

from urllib2 import Request

from urllib2 import URLError

from urllib import urlencode

# 替换你的 API_KEY

API_KEY = '你的APIKEY'

# 替换你的 SECRET_KEY

SECRET_KEY = '你的Secret Key'

# 信息内容文本

TEXT = "这里填写你要转成语音的文字"

TTS_URL = 'http://tsn.baidu.com/text2audio'

""" TOKEN start """

TOKEN_URL = 'http://openapi.baidu.com/oauth/2.0/token'

# 发音人选择, 基础音库：0为度小美，1为度小宇，3为度逍遥，4为度丫丫，

# 精品音库：5为度小娇，103为度米朵，106为度博文，110为度小童，111为度小萌，默认为度小美

PER = 0

# 语速，取值0-15，默认为5中语速

SPD = 5

# 音调，取值0-15，默认为5中语调

PIT = 5

# 音量，取值0-9，默认为5中音量

VOL = 5

# 下载的文件格式, 3：mp3(default) 4： PCm-16k 5： pcm-8k 6. wav

AUE = 3
