【问题描述】：

我正在 python 上制作语音助手。
代码如下：

import os
import time
import playsound
import speech_recognition as sr
from gtts import gTTS


def speak(text):
    tts = gTTS(text=text, lang="en")
    filename = "voice.mp3"
    tts.save(filename)
    playsound.playsound(filename)


def get_audio():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        audio = r.listen(source)
        said = ""

        try:
            said = r.recognize_google(audio)
            print(said)
        except Exception as e:
            print("Exception: " + str(e))

    return said

text = get_audio()

if "hello" in text:
    speak("Hi, how are you?")

当我说“你好”时，它会思考 2 秒钟，然后说“嗨，你好吗？”
也许是因为我正在保存 mp3 文件？如何让程序无延迟应答？

【问题讨论】：

您是否尝试识别以前录制的文件以查看需要多长时间？您是否尝试过计算捕获所需的时间并与识别的总体时间进行比较？使用 time.perf_counter docs.python.org/3/library/time.html
只是'time.perf_counter()'？没有'time.perf_counter(2)'？
不确定 2 的用途。像在第一个 starttime = time.perf_counter() 中一样使用它，然后是你想要计时的代码，然后是 elapsed=starttime-time.perf_counter() 并使用 elapsed...
糟糕，我的意思是elapsed=time.perf_counter()-starttime
哇！有用！快一点）谢谢！
