Python 如何在文本转换为语音时打印

我希望我的python程序在将文本转换为语音的过程中打印，但在说话后获取输入需要一段时间。。。请提出任何想法（：

你可以把演讲变成一条线索。

import pyttsx3
import math


speaker = pyttsx3.init()

speaker.say("Enter operator")
speaker.runAndWait()

print("Valid Operators:\n"
      "type \"add\" for adding\n"
      "type \"subtract\" for subtracting\n"
      "type \"divide\" for dividing\n"
      "type \"multiply\" for multiplying\n"
      "type \"Square root\" for square-root\n"
      "type \"Square\" for square of a number\n")
op = input("Enter your operator:\n")

import pyttsx3
import math
import threading

speaker = pyttsx3.init()

def say_thread(s):
    speaker.say(s)
    speaker.runAndWait()

def say(s)
    x = threading.Thread(target=say_thread, args=("Enter operation",))
    x.start()

say( "Enter operation" )
print("Valid Operators:\n"
      "type \"add\" for adding\n"
      "type \"subtract\" for subtracting\n"
      "type \"divide\" for dividing\n"
      "type \"multiply\" for multiplying\n"
      "type \"Square root\" for square-root\n"
      "type \"Square\" for square of a number\n")
op = input("Enter your operator:\n")```
