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
“””
获取token
“””
def fetch_token():
params = {‘grant_type’: ‘client_credentials’,
‘client_id’: API_KEY,
‘client_secret’: SECRET_KEY}
post_data = urlencode(params)
if (IS_PY3):
post_data = post_data.encode(‘utf-8’)
req = Request(TOKEN_URL, post_data)
try:
f = urlopen(req, timeout=5)
result_str = f.read()
except URLError as err:
print(‘token http response http code : ‘ + str(err.code))
result_str = err.read()

tex = quote_plus(TEXT) # 此处TEXT需要两次urlencode
params = {‘tok’: token, ‘tex’: tex, ‘per’:PER,’cuid’: “quickstart”,
‘lan’: ‘zh’, ‘ctp’: 1} # lan ctp 固定参数
data = urlencode(params)
req = Request(TTS_URL, data.encode(‘utf-8’))
has_error = False

has_error = (‘content-type’ not in headers.keys() or headers[‘content-type’].find(‘audio/’) < 0)
