首先注册和登陆百度语音
免费领取资源
创建应用
记下自己的 APIkey和 Secret Key写入代码对应的位置
代码如下:
# 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.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,

if __name__ == '__main__':

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
try:
f = urlopen(req)
result_str = f.read()
headers = dict((name.lower(), value) for name, value in f.headers.items())
has_error = ('content-type' not in headers.keys() or headers['content-type'].find('audio/') < 0)
except URLError as err:
print('http response http code : ' + str(err.code))
result_str = err.read()
has_error = True
import time
localtime = time.localtime(time.time())
time = str(time.strftime('%Y%m%d%H%M%S',time.localtime(time.time())))
save_file = "errorinfo.txt" if has_error else time+'.mp3'
with open(save_file, 'wb') as of:
of.write(result_str)
if has_error:
if (IS_PY3):
result_str = str(result_str, 'utf-8')
print("api error:" + result_str)
print("file saved as : " + save_file)
运行后会生成一个时间名称的 MP3,相关的参数我已经在代码里写了注释,需要的话加入到代码91行 的 params里就可以了
如果报以下错误信息是因为百度申请的资源还没下来,或者你还没有申请免费资源。
{"err_detail":"16: Open api characters limit reached","err_msg":"16: Open api characters limit reached","err_no":502,"err_subcode":16,"tts_logid":3405513447}
有问题留言或私信的可以一起研究。
