Python 通过 百度 rest 进行 语音翻译成中文文字。

挺简单直接代码：

import base64
from urllib import request, parse
import json
import requests
import os
import urllib#获取通行证token。
def get_token():client_id = 'cy57gvVAsEpxHpwtBB9zI9np'client_secret = 'T0QiUe8DGXUIS0mIABodTXGhVViTtGYr'login_data = parse.urlencode([('grant_type','client_credentials'),('client_id', client_id),('client_secret', client_secret)])req = request.Request('https://openapi.baidu.com/oauth/2.0/token')with request.urlopen(req, data=login_data.encode('utf-8')) as f:data  =  f.read().decode('utf-8')token = json.loads(data)['access_token']return token#获取语音数据speech
def get_base64_wav():path = 'D:\Python3Projects\TorndoServer3\scr\RESTTEST\\Microphone.wav'print(path)with open(path, 'rb') as f:wav = f.read()print('wav : ',type(wav))wav_base64 = base64.b64encode(wav).decode('utf-8')size = len(wav)f2 = open('D:\Python3Projects\TorndoServer3\scr\RESTTEST\\test.txt','w')f2.write(wav_base64)f2.close()return wav_base64, size#直接获得识别后的文字数据
def post_wav():token = get_token()speech,size = get_base64_wav()print('likai : ',size)dict_name_value_pairs = {'format':'wav','rate': 8000,'channel': 1,'cuid': 'yxh5274','token': token,'speech': speech,'len': size,'lan': 'zh'}headers = {'Content-Type' : 'application/json'}post_data = json.dumps(dict_name_value_pairs)url = 'http://vop.baidu.com/server_api'data = requests.post(url, data = post_data, headers = headers)print (data.text)post_wav()
