使用Python的语音助手

众所周知， Python是适合编剧和开发人员的语言。让我们使用Python为语音助手编写一个脚本。可以根据用户的需要对助手的查询进行操作。
语音识别是将音频转换为文本的过程。这通常用于 Alexa、Siri 等语音助手Python提供了一个名为SpeechRecognition的 API，允许我们将音频转换为文本以进行进一步处理。在本文中，我们将研究使用Python中的 SpeechRecognition API 将大或长的音频文件转换为文本。

需要的模块

• 子进程：-该模块用于获取系统子进程的详细信息，这些详细信息用于各种命令，例如 Shutdown、Sleep 等。该模块内置于Python中。
  
• WolframAlpha :-它用于使用 Wolfram 的算法、知识库和 AI 技术计算专家级答案。要安装此模块，请在终端中键入以下命令。

pip install wolframalpha

• Pyttsx3：-该模块用于在离线工作的程序中将文本转换为语音。要安装此模块，请在终端中键入以下命令。
  点安装 pyttsx3
  
• Tkinter：-该模块用于构建 GUI，并内置于Python中。该模块内置于Python中。
  
• Wikipedia：-众所周知，Wikipedia 是一个很好的知识来源，就像 GeeksforGeeks 一样，我们使用 Wikipedia 模块从 Wikipedia 获取信息或执行 Wikipedia 搜索。要安装此模块，请在终端中键入以下命令。

pip install wikipedia

• 语音识别：-由于我们正在构建语音助手的应用程序，其中最重要的事情之一是您的助手可以识别您的声音（意味着您想说/问什么）。要安装此模块，请在终端中键入以下命令。

pip install SpeechRecognition

• Web 浏览器：-执行 Web 搜索。该模块内置于Python中。
  
• Ecapture：-从您的相机中捕捉图像。要安装此模块，请在终端中键入以下命令。

pip install ecapture

• Pyjokes：- Pyjokes 用于在 Internet 上收集Python笑话。要安装此模块，请在终端中键入以下命令。
  点安装 pyjokes
  
• 日期时间：-日期和时间用于显示日期和时间。这个模块是Python内置的。
  
• Twilio：- Twilio 用于拨打电话和发消息。要安装此模块，请在终端中键入以下命令。

pip install twilio

• 请求：请求用于发出 GET 和 POST 请求。要安装此模块，请在终端中键入以下命令。
  pip 安装请求
  
• BeautifulSoup： Beautiful Soup 是一个库，可以轻松地从网页中抓取信息。要安装此模块，请在终端中键入以下命令。

pip install beautifulsoup4

注意：如果您不想获得该功能，您可以删除一些导入文件，因为这里 twilio 用于拨打电话和消息，如果您不想使用，您可以简单地删除该函数。

执行
导入以下库。

Python3

import subprocess
import wolframalpha
import pyttsx3
import tkinter
import json
import random
import operator
import speech_recognition as sr
import datetime
import wikipedia
import webbrowser
import os
import winshell
import pyjokes
import feedparser
import smtplib
import ctypes
import time
import requests
import shutil
from twilio.rest import Client
from client.textui import progress
from ecapture import ecapture as ec
from bs4 import BeautifulSoup
import win32com.client as wincl
from urllib.request import urlopen

现在我们将引擎设置为 Pyttsx3，它用于Python中的文本到语音，而 sapi5 是 Microsoft 语音应用程序平台接口，我们将使用它来实现文本到语音函数。

Python3

engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[1].id)

您可以在使用助手时将男性语音的语音 ID 更改为“0”，我们将女性语音用于所有文本到语音

Python3

def speak(audio):
    engine.say(audio)
    engine.runAndWait()
 
def wishMe():
    hour = int(datetime.datetime.now().hour)
    if hour>= 0 and hour<12:
        speak("Good Morning Sir !")
  
    elif hour>= 12 and hour<18:
        speak("Good Afternoon Sir !")  
  
    else:
        speak("Good Evening Sir !") 
  
    assname =("Jarvis 1 point o")
    speak("I am your Assistant")
    speak(assname)
     
 
def username():
    speak("What should i call you sir")
    uname = takeCommand()
    speak("Welcome Mister")
    speak(uname)
    columns = shutil.get_terminal_size().columns
     
    print("#####################".center(columns))
    print("Welcome Mr.", uname.center(columns))
    print("#####################".center(columns))
     
    speak("How can i Help you, Sir")
 
def takeCommand():
     
    r = sr.Recognizer()
     
    with sr.Microphone() as source:
         
        print("Listening...")
        r.pause_threshold = 1
        audio = r.listen(source)
  
    try:
        print("Recognizing...")   
        query = r.recognize_google(audio, language ='en-in')
        print(f"User said: {query}\n")
  
    except Exception as e:
        print(e)   
        print("Unable to Recognize your voice.") 
        return "None"
     
    return query
  
def sendEmail(to, content):
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.ehlo()
    server.starttls()
     
    # Enable low security in gmail
    server.login('your email id', 'your email password')
    server.sendmail('your email id', to, content)
    server.close()
